Platinum Resistance Temperature Detector
M 620
M series PRTDs are designed for large volume applications where long term stability, interchangeability and accuracy over
a large temperature range are vital. Due to the high resistance values of 1000 and 2000 the signal gain is excellent.
Typical applications are found in Automotive, White goods, HVAC, Medical and Industrial equipment.
