TRE.C40 series temperature sensors are resistance temperature detectors (RTDs) designed for measuring the surface temperature of pipes with diameters from 12 to 200 mm. The housing is made of brass and features a contact surface with a bending radius of 25 mm.
TRE.C40 temperature sensors are manufactured with Pt100 and Pt1000 platinum sensing elements (Class B) and have nominal static characteristics according to GOST 6651.
Standard modifications of TRE.C40 sensors are manufactured with a 1.5-meter cable.
