Abstract
A method and device, for a heat exchanger which is provided with gaskets, for assessing and detecting the risk of fluid leakage in the heat exchanger due to worn-out gaskets. In the heat exchanger, a heat transfer plate (5) with gasket (6) is provided with a pressure sensor (15) which monitors the pressure between the plate (5) and the gasket (6). A further sensor is adapted to the heat exchanger for monitoring the pressure of the fluid entering the heat exchanger.

1-13. (canceled)
A method for assessing, in a heat exchanger having a number of heat exchanger plates and intermediate gaskets therebetween, the functionality of a gasket material comprising
- using a first sensor to monitor a compression pressure of a gasket material,
- registering and processing in a processor a value monitored by the first sensor to assess an associated risk of leakage of a fluid flowing through the heat exchanger,
- comparing the value monitored with a predetermined set-value and
- in the event of deviation between the monitored value and the predetermined set-value, activating an indicator before leakage through or past the gasket occurs.
