In the field of improving reliability and prolonging work time of marine power plant

vibration measuring has been an important subject of marine engineering testing.In order to diagnose mechanical fault and monitor vibration state of marine power plant

a marine vibration measuring instrument based on piezoelectric acceleration transducer is designed.Signal is converted stably by differential operational circuit and voltage shunt negative feedback circuit

Butterworth filtering circuit and other circuits are used to modulate signal.The voltage signal output of instrument is stable which meets precision requirement for mechanical vibration measuring and matches most vibration analyzer on market

and has been widely used in engineering.
