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.
