Why are Hot Spot™Sensors superior

for AsphaltProduction?

H.E.A.T. INC.

Virtually any step of the productionprocess can now be monitored and with alonger lasting Non-Contact Red Eye Sensor.Temperature measurements can beincorporated into recording devices,control loops, and indicators through ananalog output. If a pre-existing chartrecorder is not available, don’t worry. TheRed Eye Sensor is also available with easy-to-use data logging software andhardware. This allows for fast and accurateinformation storage straight to a personalcomputer. The program allows thisinformation to be conveniently emailed tothe producers QC department or otherdepartments requiring this information.

Accurate temperature measurementis the most critical component for productquality in the Hot Mix asphalt industry. Evenmore so today with the many mixes andtight standards required of those mixes. Inthe past, the only option for temperaturemeasurement for mix has beenthermocouples. Over time, these canbecome unreliable due to a number offactors. The thermocouple has to be inconstant contact with the material toensure accurate measurement of the mix.Depending upon the production rate andthe insertion length of the thermocouple;the contact of the thermocouple andmaterial is not consistent. Further, the wearand tear on the thermocouple also has anegative effect on the ability of thethermocouple to provide accuratetemperature measurement of the mix. HotSpot™ Non-Contact Pyrometers useadvanced Infrared technology to providefast and accurate measurement of producttemperature, without ever having to comein contact with it. They are very versatile andcan function anywhere as long as there is aclear line of sight to the target. Allowingthem to measure objects in the harshestenvironments, without being subjected tothem. This negates the need to replaceworn and failing thermocouples therebyreducing operating costs associated with anew thermocouple, plant downtime andpotential defective material.

Hot Spot™ Non-contact Pyrometers are perfect formeasuring mix temperature as it moves out of the dryer and

up the conveyer.

Hot Spot™ Sensorsare built to withstandthe harsh conditionsof an asphalt plant.

H.E.A.T. INC.

Hot Spot™ Sensors are specificallydesigned to operate in the severe workingconditions of an asphalt plants. All electricalcomponents are sealed in an NEMA 4 ratedenclosure and the sensing head itself has astainless steel NEMA 4 rated body. To provideextra protection every sensor comes equippedwith an air purging sight tube to provide coolingand prevent debris from blocking the sensors lineof sight. An optional water-cooled housing unitand an air purge collar can be provided to addextra cooling, if needed.

Installation andMounting is Easy

Hot Spot™ Sensors come equipped with a 2 axismounting bracket, and dual laser targeting whichindicate line of sight and spot size. This allows for quickand easy installation and targeting of the sensor.

Optional hardware and software can be added that will transfer the information from theRed Eye Sensor to a computer. The data loggers can store temperature readings, scale factors,and offset values. The user can program specified recording times, length and recordingintervals. The software converts your PC into a real time paperless strip chart recorder. Data canbe printed in graphical or tabular format and can be exported to a text or Microsoft Excel file.
