ABSTRACT:
To provide a piezoelectric pressure pickup for a fuel injection line, a piezoelectric ceramic plate is mounted between two pressure plates within a pipe clamp which is clamped around the fuel line and has a low coefficient of expansion compared to that of the injection line. One side of the piezoceramic plate is acted upon through one of its pressure plates by a force transmission element and is braced on the other side with a leaf spring which is compressed by means of a pressure screw.
