ABSTRACT:
A transducer device is provided which is arranged to be mounted on flow path-defining structure of a fuel injection system, preferably on the outside of a delivery valve housing including a chamber in which a surge of pressure is built up during operation of the injection pump to cause a transducer of the device to develop a high amplitude and high rate of change electrical signal. The device is readily clamped in place and is light in weight with a center of gravity close to the axis of the chamber, the effect of engine vibrations being minimized. The signal from the device and a signal developed at a predetermined rotational position of the engine crankshaft are applied to an instrument which indicates the relative timing of the signals and the RPM.
