Mineral Insulated Resistance thermometers (RTD) are constructed from continuous lengths of mineral insulated copper wires cased in soft annealed stainless steel or other heat resistant metal. This gives a flexible sensor with good heat resistance, in a range of diameters and almost any length.
The PT100 sensors can be in single, duplex or triplex format, with 2, 3 or 4 wire connection format.
It can be supplied as a plain stem with flying leads or with terminal head or connectors.
