Abstract
A cooled pressure sensor includes a first housing part with inlet and out pipes for a cooling medium and a second housing part sealed gas-tight by means of a membrane and containing a signal generating element for force or displacement sensing. Several cooling channels are located in the wall of the second housing part, the coding channel being at least indirectly connected to the inlet and outlet pipes and positioned around the signal generating element to be cooled and/or are directed towards the membrane subject to high thermal loads to achieve better cooling performance.
Claims8
A cooled pressure sensor with a first housing part containing separate inlet and outlet pipes for a cooling medium, and a second housing part sealed gas-tight by means of a membrane and containing a signal-generating sensor element, wherein a plurality of cooling channel means are provided in a wall of said second housing part surrounding said signal-generating sensor element, said cooling channel means extending in a cage-like manner around said signal-generating element and being in communication with said inlet and outlet pipes for conveying cooling medium supplied by said inlet pipe around said signal-generating sensor element to cool said signal-generating sensor element and to said outlet pipe for discharge.
