Platinum Resistance Temperature Detector
M 620 10kOhm
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 value of 10 kΩ the signal gain is excellent. Typical
applications are found in White goods, HVAC, Medical and Industrial equipment.
