The ST 50 is a temperature sensor with a measuring range from from -50 to +250 °C (Pt100). Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature.

The SF 50 cable temperature probe with resistive element can measure from -50 to +260 °C (Pt100). Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature.
