Cooling Condensation

Cause

If a pipe sensor pocket is mounted incorrectly on a cooling system condensation can build up in the pocket and corrode the sensor.

Resolution

  1. Cooling system sensor pockets should be mounted at an angle to prevent condensation building up in the pocket.  See datasheet for the DWT0001, click here.  For the STP660 click here.
