Abstract
The invention refers to a plate heat exchanger, which includes a sensor device and a plate package of heat transfer plates (). The heat transfer plates form between the plates () first passages () for a first fluid and second passages () for a second fluid. The sensor device includes a space (), which is closed to the first passages () and the second passages (). The closed space () is arranged to contain a medium, which can be influenced by the temperature of at least one of the fluids, and to be connectable to a device () for sensing a pressure change of the medium in the closed space (). The closed space () is at least partly defined by at least one of the plates ().
