Differential pressure measurement is necessary to monitor leaks in plate heat exchangers. Here, the differential pressure between the plates should be 2 to 4 bar. This can be implemented with 2 pressure transmitters and a controller as well as with 1 differential pressure transmitter.
|Temperature of the ice water||1 to 2 °C|
|Operating pressure||10 bar|
|Pressure differential||2 to 4 bar|
