Claim:
1. A double wall heat exchanger plate, comprising a heat transfer area, and an edge area, which extends around and outside the heat transfer area, wherein the double wall heat exchanger plate is formed by two adjoining plates compressed to be in contact with each other, wherein the double wall heat exchanger plate comprises a sensor which is located in the heat transfer area and 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 that is provided between the adjoining plates of the double wall heat exchanger plate, said parameter comprising the capacitance, wherein the double wall heat exchanger plate is configured to be included in a plate heat exchanger having a plurality of the double wall heat exchanger plates being arranged beside each other to define a plurality of first plate interspaces for a first medium and a plurality of second plate interspaces for a second medium, wherein the sensor comprises an insulation which insulates the sensor probe from electric contact with the adjoining plates, and wherein the sensor is configured to be disposed in one of the first or second interspaces.
