ELHART TRE.V60 series temperature sensors are designed for measuring air temperature in ventilation system ducts.
TRE.V60 sensors are manufactured with Pt100 and Pt1000 platinum sensing elements and accuracy class B according to GOST 6651. The operating temperature range is from -40 to +80 °C. The immersion length of the measuring probe is specified upon ordering and can be manufactured with a length from 100 to 250 mm.
Cable is inserted into the sensor housing through the PG7 cable gland. The sensor has a screw terminal block for connecting wires.
