ABSTRACT:
A transducer for measuring the internal pressure in pipes, preferably injection pipes of diesel engines by determination of pipe deformations, comprises a rigid housing enclosing the pipe in which the pressure is to be measured, and at least one elastic sensor element arranged inside the housing and adjacent to at least a part of the circumference of the pipe. The sensor element and the housing are detachably mounted on the pipe and between the housing and the sensor element there is arranged an endorsing element elastically forcing the sensor element against the pipe whereby deformations of the pipe are transmitted frictionally to the sensor element.
