A HEAT EXCHANGER PLATE AND A PLATE HEAT EXCHANGER

摘要

The invention refers to a plate heat exchanger and a heat exchanger plate (1). The heat exchanger plate for a plate comprises a heat transfer area (10) and an edge area (11), extending around the heat transfer area. The heat exchanger plate is a double wall plate formed by two adjoining plates compressed to be in contact with each other. The heat exchanger plate comprises a sensor (20) which is configured to sense at least one parameter and to produce a signal depending on the parameter and that the sensor comprises a sensor probe (21) that is provided between the adjoining plates.
