Design & SelectionWorking fluid1 Do not use this product for flammable fluids.

Work environment1 Explosion-proof environment

Do not use this product in an atmosphere containingflammable gas. It does not have an explosion-proofstructure, so flame or fires could occur.

2 Applicable fluidsThere is a risk of oxygen deficiency if nitrogen gas isused for the applicable fluid. Observe the followingpoints when handling:

(1) Use this product in a well-ventilated place.(2) Ventilate the area while using nitrogen gas.(3) Regularly check nitrogen gas piping for leaks.

1 Sensor and monitor combinationWith the conventional PF4000/8000, the sensor andmonitor were used as a non interchangeable pair.The PF500D, 1000D, 2000D, 4000D, 8000D, and 16000DSeries have independent sensors and monitors. Sec-tions within the same model series can be inter-changed.

(1) PF4000/8000<Example>

• Only sensor A can be connected to monitor A. Sensor Bcannot.

(2) PF500D/1000D/2000D/4000D/8000D/16000E<Example>

• Sensors A, B, and C can be freely inter-changed and connected with monitor A ifsensors are from the same model.

• Differing models cannot be interchanged.• Old and new models cannot be interchanged.

2 Use within an ambient temperature range 0 to 50°C.3 Avoid using in areas where vibration exceeds 49m/s2

and impact 294m/s2.

Working fluid1 This product is not to be used as a business meter.

This product does not conform to Measuring Laws,and thus cannot be used for commercial purposes.Use this sensor for industrial applications.

2 Compressed air or nitrogen can be used. Do not use otherfluids or the precision cannot be guaranteed.

3 Compressed air from the compressor containsdrainage – water, oil oxide, foreign substances, etc. –so install a filter, air dryer, and oil mist filter on theprimary side (upper stream side) of the sensor. Thesensor's meshing rectifies flow in the pipe. It doesnot filter out foreign substances, so provide a filter.

Working environment1 Corrosive environment

Do not use this product in an environment containingcorrosive gases such as sulphur dioxide.

2 Fluid temperatureKeep the fluid temperature within 0 to 40°C.Do not use this product where temperature suddenlychanges, even if ambient temperature is withinspecifications. Otherwise, dew could form.

1 Set the power voltage and output at the specifiedvoltage.Application of voltage exceeding the specifiedvoltage could result in malfunctions, sensor dam-age, electrical shock, or fire.

Do no use a load exceeding the output rating.Failure to observe this could result in output dam-age or fire.

Wiring1 Check the wire color and terminal numbers when

wiring. Incorrect wiring connections could result in

sensor damage, problems, and malfunctions, so

check wire color and terminal numbers against the

instruction manual before wiring.

Use a wire with the same or higher performance

than the 600 V vinyl wire for the power supply and

other wiring. Insert a noise filter if required.

2 Ground the FG terminal with Class 3 grounding(100ΩΩΩΩΩ or less). Do not use a common ground with

the power distribution system.

3 Check wiring insulation.Check that wires do not contact other circuits and

that there are no ground faults or insulation faults

across terminals. Overcurrent could flow in and

damage the sensor.

4 Separate the monitor from high-voltage wires, highvoltage devices, and powered devices such as

motors.

5 Check that there are no swarf or wire scraps on themonitor's gland and sensor connectors before wiring.

4 Do not install a regulator before the sensor (on theprimary side).

5 When using an elbow or bushing (up to 1 port sizerank difference) in piping for the PF16000E Series,

install a 10D or larger straight pipe on the up-

stream side and a 5D or larger straight piping

section on the downstream side. If there is no

straight piping section, drift (turbulent flow) could

occur and result in an error.* "D" here refers to the piping material bore.

Wiring1 Separate the cable from sources of noise such as

power distribution wires.

Failure to do so could result in malfunctions caused

by noise.2 Use the enclosed cable PF-FL-280774 (3 m) to wire

the sensor to the monitor. Use the CKD extension

cable PF-FL-280775 (length 3 m) to extend the cable.

The enclosed cable can be connected to the exten-

sion cable for a maximum of 6 m. Contact CKD if

longer distances are required. The extension cable is

compatible with all models.

3 Do not short-circuit the output contact.4 Do not use this product for loads generating surge

voltage. When directly driving a load that generates a

surge, such as a relay or solenoid valve, use a

sensor with integrated surge absorbing element.

Similarly, use surge countermeasures if there is a

source of surge in the power supply line. (Refer to

"Protection circuit for monitor contact" on the

following page.)5 Do not repeatedly bend or tension to leads or wires

could disconnect.

Variable resistor

** When using with an AC voltage, check

that load impedance is sufficiently smaller than CR impedance.

When the load is a relay or solenoid, recovery time is delayed. Connect the circuit between loads when using a 24 or 48 V power voltage and across contacts for a 100 to 200 V power voltage for maximum effect.

Energy accumulated in coils is passed as current by the parallel diode, and consumed as Joule heating by inductive load resistance. Recovery for this takes even longer than for CR.

This is effective when recovery of the diode is too slow.

This uses the constant voltage of the variable resistor to prevent very high voltage from being applied across contacts. Recovery is also slower with this method. Connect the circuit between loads when using a 24 to 48 V power voltage and across contacts for a 100 to 200 V power voltage for maximum effect.

The guide for C and R is:C: 1 to 0.5 (uF) of the contact current 1 AR: 0.5 to 1 (W) of the contact voltage 1 V.

These may not necessarily match due to dispersion in load characteristics, etc.Test the state while considering that C is affected by discharge suppression when the contact is opened, and R plays a role in suppressing current when power is turned ON next.Generally, C should have a withstand voltage between 200 and 300 V. When an AC circuit is involved, use an AC capacitor (no polarity).

Use a diode with a reverse withstand voltage that is 10-fold or more than circuit voltage and for which forward current is larger than load current. If circuit voltage is not that high for the electronic circuit, a diode with a reverse withstand voltage 2 to 3 times larger than the power voltage can be used.

The Zener voltage of the Zener diode is approximately the same as the power voltage.

Select cut voltage Vc to satisfy the following condition: When using alternating current, voltage must be multiplied by .

• Avoid using the following arc suppressors:

These are extremely effective for extinguishing arcs at cut off, but capacity is accumulated in C when the contact is opened. C's short-circuit current flows when the contact is tripped and causes the contact to melt easily.

This is extremely effective for extinguishing arcs at cutoff, but charged current flows to C when the contact is tripped, causing the contact to melt easily.

• It is usually more difficult to switch a DC induction load than to a resistance load, so performance can be increased to the same level as the resistanceload by using an appropriate arc suppressor.

• Keep wiring short to prevent effects from noise. Separate wire from sources of noise such as power distribution cables.

• If the ratings at left are exceeded, use anauxiliary relay to turn the load ON and OFF.

• When using an inductive load, such as anauxiliary relay, on the relay contact's out-put, use a CR filter as the arc suppressorcircuit (when using AC), or protect the cir-cuit with a diode, etc.(Refer to the Contact protection circuit formonitor section on page 1011.)

The sensor section consists of a rectifier that passesan even amount of compressed air, a heater tem-perature detection resistor with integrated heater,and fluid temperature detection resistance for de-tecting fluid temperature.When compressed air is not flowing, electricity flowsto the heater at the heater temperature detectionresistor to maintain it at a set temperature. Whencompressed air flows, heat is lost in proportion tothe air mass, so current flows to the heater tem-perature detection resistor to maintain the set tem-perature.The monitor receives a signal indicating the amountof electricity that has flowed, and displays the air'sinstantaneous and cumulative flows obtained byconverting to 0°C with practical atmospheric pres-sure.The fluid temperature detection resistor measuresand compensates for the temperature of com-pressed air.
