Platinum Resistance Temperature Detector
M 422
M series PRTDs are especially robust and are designed for large volume applications where long term stability,
interchangeability and accuracy over a large temperature range are vital. Typical applications are Automotive, White
Goods, HVAC, Energy Management, Medical and Industrial Equipment.
