Ultrasonic probe for sensor

The utility model provides an ultrasonic probe for a sensor. The ultrasonic probe comprises an assembling housing, a copper shielding and sealing housing, a twin-core shielding wire, a circuit board arranged inside the copper shielding and sealing housing, a foam soundproofing insulating ring, a piezoelectric ceramic body arranged inside the foam soundproofing insulating ring and a retaining screw. The foam soundproofing insulating ring and the piezoelectric ceramic body are arranged inside the copper shielding and sealing housing; the twin-core shielding wire is respectively connected with the circuit board and the copper shielding and sealing housing; the circuit board is connected with a silver electrode of the piezoelectric ceramic body by means of an inner electrode leading wire; and one end of the retaining screw is movably connected with the copper shielding and sealing housing while the other end is fixedly connected with the assembling housing. The ultrasonic probe for a sensor is capable of reducing
