Installation guide of immersion temperature sensors · Water

Ensure that the full active length of the sensor is immersed in the medium.

Incorrect installation

Chilled water and refrigeration pipes

To prevent condensation, extend the immersion pocket inside the lagging by use of a plastic sleeve.

Chilled water and refrigeration pipes

The hole in the lagging must be sealed, to prevent the ingress of moisture (water-resistant seal).

Install sensors against the direction of flow.

Incorrect installation

• If the active length (a) of the sensor probe is longer than the diameter of the pipe, the sensor should be installed diagonally, or in a bypass pipe or bend.
  
• The inlet side of the bypass pipe should project into the main pipe.
  

• Maintain a clearance (distance A) between the sensor and any obstruction, so that there is room to remove the sensor from the immersion pocket.
  
• For each sensing point, an additional immersion pocket, adjacent to the sensor, must be provided for test purposes.
  
• Install outlet-temperature sensors directly at the heat exchanger outlet.
  

Sensors mounted without immersion pockets or with slotted or perforated immersion pockets must be identified accordingly.
Attach a label marked: Installed without immersion pocket.

 

When mixing water at different temperatures, always maintain an adequate distance between the mixing point and the sensor (to take account of stratification).
