Abstract
A transducer for detecting pressure changes in pipes by detecting deformation of the pipes and for converting the pressure changes in the pipes into electric signals uses a bimorph as a sensor element. This bimorph is pressed to the pipe surface by means of a holder. The transducer is free from complicated adjustment of the pressing force against the sensor element, very simple in structure, easy to adjust when mounting, light in weight so as to hardly influence an injection system, and less susceptible to effects of noise due to vibration.
