What is the simple relationship between windingsthickness and re-sistanceinductance

The simplest inductor is a single turn of stiff wire with air in the centre (aircore) If a metal object is placed in the centre of the turn the inductance isincreased If additional turns are added the inductance is increased If thediameter of the turn is increased the inductance is DECREASED If the turnsare stretched apart the inductance of the coil DECREASES

15

RoughlyL (inductance) of an air core cylinder coil =(air permeabilitynumber of turnsarea of cross section)length of coilL for a multilayer coil with ferrite core =air perm ferrite perm N(number of windings) squared (arealength)Resistance is roughly lengthcross sectional area so thicker wires have less

resistanceSee also httpwwwepanoramanetdocumentscomponentscoilshtml

What is the relationship between windingsthickness inductance andmagnetic field densityflux

Faradayrsquos lawsFlux density= (inductancecurrent) (number of windings areacross sec-

tion)(So if we have thicker wire we have less windings in the given area and so

more flux but what of inductance)Current(I)=VR

Measuring the field

Using our gaussmeter Gauss is the unit of mag field (flux density) Relation ofgauss to tesla

1 tesla=10000 gauss 1 gauss=100 microTesla (uT)=00001 TeslaWe aim for around 1 uT=001 gauss = 10 milligauss (as in shakti)

Calculate the limiting resistor

290 Everyday Practical Electronics April 2003

electrically probing the soil in theirsearch for minerals and oil deposits(since 1946 says Robert Beck) it hasbeen found that there are better probingtechniques than just using two probesSome of these have been adopted byarchaeologists

Most of the favoured ones all use fourprobes ndash two for transmission (TX) andtwo for reception (RX) The righthand sec-tion of Fig2 shows one way in which thesecond pair of probes can be used AnthonyClark says that there are also some tech-niques that use five probes ndash with push-pullTX across two and the fifth becoming agrounded reference perhaps

There are several ways in which four

probes are used in relation to each otherand each with its own merits Their use isoutlined later but no quality judgement isoffered here on their appropriateness to

various survey situations ndash but it is worthnoting that Clark considers the Twin-Probetechnique to be the most favoured forarchaeological surveying although theWenner technique is said to provide moredetailed results Nick in his extensive useof the prototype adopted the Twin-Probetechnique

The Twin-Probe and Wenner techniqueswere outlined in Robert Beckrsquos article andwere used in the authorrsquos garden tests withthis Logger They will be discussed in Part2 in a bit more detail Suffice to say for themoment both involve placing in the soil areference probe that is connected to the cir-cuitrsquos 0V line (common ground) This isregarded as one half of the TX probes pair

To the other TX probe is fed the alter-nating voltage or current evenly swingingas a square wave above and below the 0Vreference value The function of the TXprobes is to set up a field of potential gra-dient in the soil which is then sampled bythe RX probes

The RX probes are positioned at dis-tances away from the TX probes as dictat-ed by the probing technique being usedThey are connected to the twin inputs of adifferential amplifier whose output signalamplitude is determined by the differencein the two input levels It is this signalwhich is then monitored by the controlcircuit

It is not even necessary to use specialprobes any metal object that does not cor-rode and can be inserted into the soil with

a wire attached willdo The probes donrsquoteven need to beinserted very far justenough to penetratethe soil to makeelectrical contactwith its moistness

It will be obviousof course that drysoil will be lesscapable of passing acurrent than moistsoil Keep in mindthat the surface ofthe soil can dry outfaster than thatbelow it and so areasonable amount

of penetration should be allowed RobertBeck allows 200mm with his probe struc-tures discussed in Part 2

With some sites it may be necessary toevenly damp the soil with water beforeadequate probing can begin

13The PIC-controlled processing circuit is

almost irrelevant to the main aspects of soilmonitoring So first letrsquos look at the powersupply requirements and the simple trans-mission circuit both illustrated in Fig3

As said in Table 1 the power can origi-nate from any dc source (eg battery)ranging between about 9V and 15V This isinput via diode D1 to the +5V voltage reg-ulator IC1 The diode prevents distress tothe circuit in the event of the battery beingconnected with the wrong polarity

The regulated +5V output from IC1powers the main PIC-controlled circuitwhich must not receive a supply signifi-cantly greater than +5V It also providesthe positive power to the TX and RX cir-cuits Both of these circuits additionallyneed an equivalent negative supply This isgenerated from the +5V line by the voltageinverting chip IC2 which outputs a voltageof close to ndash5V

Opamp IC3 is the device which feeds the

137Hz alternating signal to one TX probe(the ldquoactiverdquo TX probe) As previously said

the other TX probe is connected to the 0Vpower line IC3 is configured as a compara-tor whose inverting input (pin 2) is tied tothe potential divider chain formed by equal-value resistors R1 and R2 The resistors areconnected across the +5V and 0V lines andthe voltage at their junction is thus 2middot5V

The non-inverting input (pin 3) of IC3 isconnected to one of the PIC microcon-trollerrsquos output pins (RA2) and is fed witha 137Hz square wave generated by thesoftware and which alternates between+5V and 0V As this square wave repeated-ly crosses above and below the 2middot5V refer-ence voltage IC3rsquos comparator actiontakes place and its output (pin 6) alternatesbetween the devicersquos upper and lower volt-age limits ie swinging between about+4V and ndash4V

Note that the opamp to which the TXprobes are connected (IC3) is short-circuitprotected internally and is unlikely to suf-fer if the probes accidentally come intocontact with each other while the power isswitched on However do not sustain suchcontact since it could cause regulator IC1to get hot and it will shorten the batterycharge life

Depending on the probing technique

used experienced geophysicists can deter-mine not only the subterranean density butalso its possible composition This isapparently achieved by pre-setting the cur-rent which flows between the two TXprobes

Robert discussed this in the rsquo97 textreferring to the technique as providing aldquoconstant currentrdquo It would appearthough that his circuit did not provide aconstant current in the literal sense ndash samecurrent flowing irrespective of resistiveconditions ndash but rather it provided a currentlimit It is the same limiting approach thathas been taken in this Logger design

The output from IC3 can be switched byS2 to the active TX probe via one of fivepaths These comprise a direct unlimitedpath and four limiting paths via resistorsR3 to R6 in order of 10 100 1k and10k

the author and Nick Tile were carried outvia the direct TX path (Nick says he hasnot found the switchable resistance facil-ity to be useful) In this role the signalamplitude across the TX probes is pickedup by the RX probes simply as an alter-nating signal whose amplitude variesaccording to the soil density it has to passthrough

The receiving circuit is shown in Fig4

The twin RX probes and their received dccoupled signals are connected via bufferingresistors R7 and R8 to the respective inputsof the differential amplifier formed initial-ly around opamps IC4a and IC4b and hav-ing a gain of three The outputs from theseopamps are summed still as dc signalsby opamp IC4c which provides unity gain

The resulting signal represents thedifference between the two input signallevels It is now ac coupled via capacitor

C6 to the amplifying stage around IC4dHere the gain can be switched by S3between times1 times10 and times100 In the proto-typersquos garden tests the times1 gain wassatisfactory across the maximum probeseparation distance that the dense gardenflower beds would allow (11 metres) Nicksays he prefers the times10 setting

At this stage the signal is swingingabove and below 0V It has to be shifted sothat it only swings between 0V and +5V atthe maximum extremes to suit the PICmicrocontrollerrsquos limits This is achievedby ac coupling the signal via capacitor C7to the level-shifting potential dividerformed by resistors R22 and R23 DiodesD4 and D5 limit the maximum voltageswing then fed to the PIC preventing itfrom swinging above or below the PICrsquoslimits of acceptance

It will be seen that two additional signalpaths are provided from the output ofIC4ab and consist of resistors R16 and

R17 plus diodes D2 and D3 These are notpart of the required analogue processingcircuit but were included for use duringsoftware development Their function willbe described presently

The PIC-controlled processing circuit is

shown in Fig5 At its heart is a PIC16F876microcontroller IC5 manufactured byMicrochip It is run at 3middot6864MHz as setby crystal X1 The frequency may seemunusual but crystals tuned to it are stan-dard products Its choice provides greateraccuracy of the baud rate at which thelogged data is output to the computer

The software-generated 137Hz squarewave pulse train is output via pin RA2 andfed to the TX opamp IC3 in Fig3

Pin RA3 is the pin to which the level-shifted signal output from IC4d is inputThe pin is configured by the software as ananalogue-to-digital converter (ADC)

There are numerous archaeological websites with bulletin boards and ldquochat-zonesrdquoon-line if you search through the excellentwwwgooglecom or other quality internetsearch engines It is worth noting thoughthat Anthony Clark considers the Twin-Probe technique to be that most suitable toarchaeological work and is the one usedby Nick with his surveys

With all techniques the area to be sur-veyed is first marked out as a grid withtapes or similar to form squares havingsides of say one metre in length (this is acommonly quoted distance in this context)and probably forming a 20 times 20 matrixedarea see Fig8

Anthony Clark comments that plasticcovered clothes line is also useful for set-ting out a grid matrix He cautions thoughthat it can be difficult to untangle and onone site he knows of it had to be ldquoguardedin the presence of sheep by whom it wasregarded as a rare delicacyrdquo

The Twin-Probe technique is apparently

more suited to initial surveying of a siteestablishing whether or not it is worth car-rying out a more detailed survey

With this method the two probes C1 andP1 are inserted into the ground sufficientto make electrical contact with it (see earli-er) centrally to and somewhat outside thearea to be surveyed Anthony Clark dis-cusses the best distance in his book

Probe C1 is the transmitting probe con-nected to the comparator IC3 via switchS2 Probe P1 is one of the receiving probesconnected to the input of opamp IC4a

Probes C2 and P2 are inserted into theground to a similar depth at the far cor-ners of the first square to be monitored saytop left coordinate R0C0 (row 0 column0) Probe C2 is the 0V reference probe andP2 is connected to the input of opampIC4b The respective leads from the Logger

are then connected to the probes usingheavy duty crocodile clips seems theeasiest method

The Loggerrsquos storage coordinates are setto suit the square number ie to R0C0 inthis case and a reading saved to theLoggerrsquos serial EEPROM by pressingswitch S8

The C2P2 probes are then moved to thetop corners of the next square to the rightfor example to be monitored and its coor-dinates set into the Logger in this caseR0C1 Again a reading is stored to theEEPROM

The process continues fully across hori-zontally for the width of the marked surveyarea eg R0C19 (the final column of thisrow in a 20 times 20 grid) The probes are thenmoved down by one row and the processrepeated to the left this time back toR1C0 And then down by another row andso on for all 400 squares

1313Note that the relative order of all probe

connections must be maintained during thesurvey Differences in reading can result ifthe order is changed hence the earlier rec-ommendation that the plugs and crocodileclips should be colour-coded

In practice it does not matter in whichdirection you move the probes or whetheryou start the survey from the top of the gridor the bottom Note that the PC screenregards location 00 as being at top left ofthe screen

ldquoBe methodical and consistentrdquo seems tobe the key phrase though ndash this helps youto establish a routine that becomes secondnature which the author soon found whenstarting his own mini surveys

It was also soon found that it is not nec-essary to move both probes on each occa-sion Since one is already at the corner ofthe next square it is only necessary tomove the probe from the corner now

finished with putting it in the next squarersquosopposite top corner and swap the probeleads to retain the correct order

The author surveyed his garden severaltimes in different ways during designdevelopment and on each occasionbecame faster at doing so On the final sur-vey on an 11 times 7 grid (77 samples) it tookabout an hour and half

Of course during the process of doingthe test surveys several methods for speed-ing it were imagined For a solitary survey-or perhaps the most efficient in terms ofspeed would be to insert separate probes ateach corner of the matrix prior to takingreadings It would then only be required torepeatedly change the lead connections ndash aseemingly much faster ldquoconveyor beltrdquosystem No doubt though having an assis-tant would probably make the moving ofjust two probes a speedy alternative

A perhaps less practical method was(bizarrely) thought up too ndash using amotorised vehicle like a golf buggy withprobes attached to the wheels in Boadiceafashion This would then be driven backand forth across the grid the probes auto-matically inserting themselves and trigger-ing the storing of each reading at thecorrect coordinates (Well ndash a chap candream canrsquot he)

Another seemingly useful technique is

known as the Wenner configuration In thismethod the four probes are arranged in astraight line equally spaced apart say ametre between them Fig8b shows theorder of arrangement

This method is apparently better suitedto doing a more detailed survey of thematrixed grid site The principle is that theTX probes are the outer two The RXprobes are in line between them The cur-rent flows across the TX pair and is pickedup across the RX pair the received signalvalue varying with the resistance in serieswith the probes in a more direct fashionthan with the twin-probe technique

A variant of this technique theSchlumberger in which the probes are notequally spaced is discussed in AnthonyClarkrsquos book But he regards it as not ide-ally suited to archaeological surveying

Another method is known as the Square

Array in Anthony Clarkrsquos book With thismethod the TX and RX pairs are placed atthe corners of the one metre squares asshown in Fig8c The four probes aremoved as a set from square to square

The transmission signal flows betweenthe TX pair as before This time the RXpair pick up the radiated signal at the samedistance from the TX probes If the soilresistance between the TX and RX pairs isuniform so too will be the amplitude of thesignal received by both RX probes

Tests showed that because the probes areconnected to a differential amplifier if thetwo input amplitudes are the same theywill cancel each other out at the final com-bining stage (IC4c)

If on the other hand the amplitudes arenot the same the difference between themis that which will be finally output fromIC4c In this case what would be lookedfor is any difference values indicating theedge of a subterranean feature

It is evident however that balanced(zero) readings when the two input valuesare equal would only indicate the unifor-mity of the terrain in that grid It would notindicate whether that uniformity was dueto a highly resistive feature or a highlyconductive one Nonetheless the detectionof only outlines might in itself be a desir-able situation

A variant of this technique would be toplace the two TX probes at one end of acolumn and the RX pair at the other tak-ing a reading and moving both pairs to thenext column still at the top and bottompoints This could perhaps yield initialinformation about whether or not a site isworth examining more closely Not beingan archaeologist though the author can-not comment on the validity of this

Anthony Clark discusses the abovenamed probing techniques in more detailand describes others

During garden tests with the prototype

Logger individual metal rods measuringabout one metre long by 5mm diameterand with a right-angled bend at the topwere used as the probes These were pur-chased inexpensively from a garden cen-tre their intended use being to supportplants

A recently observed but not triedpossibility was in the form of long inex-pensive barbecue skewers ndash seen in a localsupermarket

If you wish to construct purpose-builtprobe structures of more durability andperhaps greater ease of use the probe

assemblies describedby Robert Beckshould be consideredSchematics of theoriginal figures illus-trating these probeshave been redrawnand are repeated hereOther than the fol-lowing details noadditional informa-tion can be offered

Robertrsquos rigidframe assembly fortwo probes is shownin Fig9 Details ofhis single probe aregiven in Fig10

His original textstates that the Twin-Probe assembly wasspecially developedand that its top mem-ber is a wooden bat-ten 30mm times 50mm times1050mm the ends ofwhich are bound withself-amalgamatingtape to form handgrips

An aluminiumplatform is attachedto the centre of thisbatten to carry thecase that holds theelectronics secured by rubber bands Thebottom member is a similar wooden bat-ten but this piece must have good insulat-ing properties (to prevent current leakagebetween the probes) He suggests that you

either dry and coat the batten with varnishor devise insulating collars of Tuffnol orsimilar material and fit them where theprobes go through the batten

The top and bottom battens are heldtogether by metal conduit pipes threadedat each end and secured by lock-nuts

In describing the construction of theother probes he says that none of theirdimensions are critical and may be dictat-ed by what is to hand In Fig10a is showna substantial probe made out of stainlesssteel tubing with a brazed on T-handle andtip which assist soil penetration Thisprobe is designed to be used by the opera-tor in the standing position

A smaller version of Fig10a is shown inFig10b This has a 4mm screw terminaladded an alternative method of wireconnection

Probes may be constructed of materialother than stainless steel which is expen-sive and a little difficult to obtain he says(provided it is corrosion resistant ofcourse)

An extremely simple probe is shown inFig10c and which may be constructedfrom 6mm diameter metal rod ie brazingor uncoated welding rod mild steel silversteel etc A depth guide consisting of aband of paint or insulating tape is addedand connections are made to the top usinga crocodile clip

The depth stop in Fig10d is adjustableby means of an Allen key The materialneed not be insulating and could be ofmetal if desired
