Resistance thermometers - Import export

The resistance probe offers a measurement of great accuracy and very good long-term stability. A Pt 100 Ohm probe corresponds to a platinum resistance whose initial value is 100 Ohms for a temperature of 0°C. The measuring element consists of wound platinum wires whose resistance varies according to the temperature. The resistance / temperature correspondence is documented in the IEC 60751 standard. The temperature probe is often delivered with a connection head (see photo opposite).
