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.
