Transducer polarity detection device

The invention discloses a transducer polarity detection device, and belongs to the technical field of sonar transducers. The transducer polarity detection device comprises a sampling unit, an amplifying unit, an amplitude modulation unit and a display unit. Specifically, the sampling unit collects an input signal of a detector; the amplifying unit amplifies the input signal and then outputs the amplified input signal; the amplitude modulation unit performs amplitude modulation on the amplified input signal to meet the display requirement; and the display unit is used for displaying the input signal after amplitude modulation. In the debugging and repairing process, the device is extremely high in detection accuracy, and is very convenient, effective and safe in the using process. In practical application, the number of paths and circuit parameters of the transducer polarity detection device can be adjusted according to specific requirements of transducers, polarity detection can be carried out on the transduc
