Pressure sensor for gas pressure measurement in e.g. motor cylinder, comprises two elastic element parts, one of which has membrane with outer tapered surface and other part has sleeve with holes, to which wire strain gauge is fastened

摘要

The sensor has a housing (6) and an elastic element onto which a wire strain gauge (12) is fixed. The elastic element consists of two parts (1,3) between which a heat insulation material is provided. The first element part has a membrane (1) with an outer tapered surface (4). The second part of the elastic element has a sleeve (3) with holes (11), which are provided at regular intervals on a circle and to which a wire strain gauge is fastened.
