A device and a method for assessing a gasket pressure of a gasket arrangement between two adjacent heat transfer plates of a plate heat exchanger is provided. The gasket arrangement seals between adjacent heat transfer plates to define a flow channel between adjacent heat transfer plates, and the gasket arrangement is arranged to be exposed to a fluid passing through the flow channel. The device comprises a test object and a holder which are adapted to be arranged in a flow path of the fluid. The holder is arranged to hold the test object and the test object is arranged to be exposed to the fluid. The device is adapted to be arranged outside a space delimited by the adjacent heat transfer plates. The test object is arranged to be evaluated for an indirect assessment of the gasket pressure of the gasket arrangement.
A device for assessing a gasket pressure of a gasket arrangement between two adjacent heat transfer plates of a plate heat exchanger, said gasket arrangement sealing between said adjacent heat transfer plates to define a flow channel between said adjacent heat transfer plates, and said gasket arrangement being arranged to be exposed to a fluid passing through the flow channel, the device comprising
A method for assessing a gasket pressure of a gasket arrangement between two adjacent heat transfer plates of a plate heat exchanger, said gasket arrangement sealing between said adjacent heat transfer plates to define a flow channel between said adjacent heat transfer plates through which a fluid flows, and said gasket arrangement being subjected to a number of specific outer conditions during operation of the plate heat exchanger, the method comprising:
A plate heat exchanger in combination with a device for assessing a gasket pressure of a gasket between two adjacent heat transfer plates of the plate heat exchanger, the gasket providing a seal between the two adjacent heat transfer plates to define a flow channel between the two adjacent heat transfer plates, the gasket being positioned to be exposed to a fluid passing through the flow channel, the device for assessing the gasket pressure of the gasket comprising a test object different from and spaced away from the gasket at a position exposing the test object to the fluid, the test object and the gasket being made of the same material, and the test object being evaluatable to indirectly assess the gasket pressure of the gasket.
