ELHART TRE.H20 series temperature sensors are designed for measuring the temperature of liquid, granular, and gaseous media non-aggressive to the sensor materials.
TRE.H20 RTDs are manufactured with Pt100 and Pt1000 platinum sensing elements of accuracy classes A and B according to GOST 6651. Wire connection is carried out via a quick-release electrical connector according to DIN 43650, providing fast and easy connection to measuring devices.
Process connection is performed by a fixed fitting with M20×1.5 or G1/2" thread. The sensors can be connected to the process directly or via a thermowell.
