ELHART TRE.V52 series temperature sensors are designed for measuring ambient air temperature in individual heating substations, meteorological stations, general ventilation systems, etc.
TRE.V52 sensors are manufactured with Pt100 or Pt1000 platinum sensing elements and accuracy class B according to GOST 6651. The operating temperature range is from -40 to +80 °C.
The measuring wires are connected to the sensor using a screw terminal connector according to a 3-wire connection scheme.
