Tempatron - PT100 Temperature sensors

                        PT100 (RTD) TEMPERATURE SENSORS

   
 

Resistance thermometer devices (RTDs) are based on the principle that electrical resistance changes with a change in temperature. Most RTDs use a platinum detector which results in a relatively linear relationship between temperature and resistance. Our range of RTD sensors use Platinum PT100 detectors, so called because the resistance of the detector is 100Ω at 0șC, and meet the requirements of class A or class B of BS EN 60751:1996.

If the type of RTD you are looking for is not shown here, please contact us as we have a very wide range of non-standard sensors available and can make pretty much any type you could want..
   
 

PT100 SENSOR - 200șC - STAINLESS STEEL HOUSING


PT100 6x100 Stainless Steel probe with 3m PTFE cable
The PT100A1 probe has an operating range of -50șC to 200șC and is packaged in a 6mm diameter x 100mm long stainless steel housing with a 3 metre length of cable. The probe meets the requirements of BS EN60751 class B. These probes are compatible with our range of analogue on/off, digital on/off and PID temperature controllers.

       


PT100 SENSOR - 400șC - STAINLESS STEEL HOUSING


PT100 6x100 Stainless Steel probe with 3m glass fibre cable
The PT100A2 probe has an operating range of -50șC to 400șC and is packaged in a 6mm diameter x 100mm long stainless steel housing with a 3 metre length of cable. The probe meets the requirements of BS EN60751 class B. These probes are compatible with our range of analogue on/off, digital on/off and PID temperature controllers.

Note : PT100 probes have an effective maximum operating temperature of 600șC. Actual operating temperature is usually limited by the cable insulation material:-

        PVC : 100șC max                                   
Si Rubber : 180șC max                                   
      PTFE : 250șC max                                   
  Glass braided : 400șC max
