Platinum Resistance Temperature Detector

HM 220

HM 220 type platinum sensors are characterised by long-term stability, precision over a broad temperature range and

compatibility. The main feature is the small design. They are used in particular for applications with high consumption

volumes, e.g. white goods and heating power.
