Pt100 sensors with cable

Pt100 probes are intended for temperature measurement, from -70°C to +400°C, of a gas, a liquid or a solid. In a gas or a liquid, the probe is immersed directly in the fluid or inserted in a pocket. In a solid, the temperature can be taken inside the piece or on its surface. A Pt100 probe is a resistor whose ohmic value increases almost proportionally with temperature (100 Ohm at 0°C and 138,5 Ohm at 100°C). This resistance measurement is carried out by the current circulation generated by a measuring device or a regulator, through copper interconnecting wires. The probe consists of a sensitive element generally protected by a rigid or flexible stainless steel sheath and an output cable. Several materials available for the cable sheath (PVC, Teflon FEP or fiberglass with metallic overbraid) depending on the conditions of use. Several measurement accuracies are possible depending on the class of the Pt100 probe.
