Hardware

Temperature Sensor

The Temperature Sensor Unit is housed in a choice of either Polycarbonate or GRP enclosure. The enclosure is rated IP67 so there is no chance of water ingress. There are no external wires/ connections on the enclosure so risk of damage is minimal. The actual temperature sensor is connected to a brass plug which is in direct contact with the underside of the rail ensuring accurate temperature measurement. The board is isolated from the enclosure to ensure that there is no danger of the components being damaged due to vibration.

The enclosure is mounted on a PVC clip that will fit all UIC profile rails. Although robust , the Unit should be removed during invasive maintenance procedures such as tamping etc.

  • Solar Panel used to recharge the battery
  • ABS IP65 Enclosure that contains:
