ELHART TRE.V50 series temperature sensors are resistance temperature detectors (RTDs) designed for measuring ambient air temperature in heating, ventilation, and air conditioning (HVAC) systems.
TRE.V50 sensors are manufactured with Pt100 or Pt1000 platinum sensing elements and accuracy class B according to GOST 6651. The operating temperature ranges from -40 to +80 °C.
The measuring wires are connected to the sensor using a screw terminal connector according to a three-wire connection scheme.
