ETC 32208181

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 Ω and 2000 Ω the signal gain is excellent.
Typical applications are found in Automotive, White goods, HVAC, Medical and Industrial equipment.
