Patent ID: 7568516

Claim:
A device for monitoring operating conditions in a heat exchanger system, the heat exchanger system comprising a plate heat exchanger having heat exchanger plates and gaskets, the plate heat exchanger, when in use, being constructed and arranged to receive at least one fluid and having a first sensor for monitoring a compression pressure of at least one of the gaskets wherein the first sensor is in or close to one or more of the gaskets, and is located in a recess arranged in one of the plates for a gasket and is adapted to monitor the pressure between the gasket and the plate. the device further comprising a second sensor for monitoring fluid pressure, and the sensor for monitoring fluid pressure is located at one point along a flow path of one fluid to the heat exchanger from a last component, seen in the direction of flow, from the heat exchanger system, said last component being the last component in the heat exchanger system to have a possibility of influencing a characteristic of the fluid to the plate heat exchanger.
