ABSTRACT:
A high pressure transducer, particularly for ballistic pressure measurements, with a sensor part, with a sealing part formed thereon and with a hollow mounting screw surrounding the sensor part with a clearance. The sensor part can be inserted together with the sealing part into a threaded mounting aperture in the component to be examined, whereby the sealing surface of the sealing part comes into sealing contact with a seating surface of the mounting aperture. The hollow mounting screw presses on the sealing part and produces the force necessary for sealing. The sealing surface of the sealing part is located somewhat ahead of a membrane portion while the sealing part is connected relatively elastically with the sensor part by means of a narrow web. The force flux lines produced by the sealing force are restricted in their effect substantially to the sealing part and do not reach the sensor element received in the sensor part; as a result thereof, a substantial independence of the measures values from the mounting conditions is attained.
