Abstract
A pressure sensor having a disk-shaped sensor body which includes a pressure space for the medium to be measured. A bolt element in the pressure space forms a tubular pressure gap of small volume. The bolt element also forms a heat accumulator before the pressure transducer surface of the sensor body and acts on a temperature compensating element to narrow the temperature swings in the sensor due to temperature shocks. The new pressure sensor may be used for hot combustion gases and for fuels and other liquid or gaseous substances. In the application for monitoring internal combustion engines, the pressure sensor is fitted between the combustion chamber and the indicator valve instead of after the indicator valve, making possible periodic blowing-through and hence the removal of all combustion residues and calibration measurement any time.
