Abstract

The invention discloses a differential output ultrasonic probe, which comprises a probe shell, an emitting wafer and a receiving wafer, the emitting wafer and the receiving wafer are both arranged on a wedge block which is arranged in the probe shell, a sound isolation layer and the wedge block are arranged between the emitting wafer and the receiving wafer, an external lead wire and an internal lead wire of the emitting wafer and an external lead wire and an internal lead wire of the receiving wafer are arranged in correspondence to the emitting wafer and the receiving wafer and are separated with each other and are arranged in insulation, and the differential output ultrasonic probe, a differential amplification integrated circuit, an emitting control circuit, an emitting circuit, an analog signal amplification processing circuit, an A / D conversion and digital processing circuit and digital control and result output constitute a signal processing device. The differential output ultrasonic probe and the signal processing device have simple structure, strong anti-jamming capability and wide application scope.

Description

technical field [0001] The invention relates to an ultrasonic probe, in particular to a differential output ultrasonic probe and a signal processing device composed of the ultrasonic probe, which is particularly suitable for roll detection, non-destructive flaw detection equipment and instruments for metal materials. Background technique [0002] At present, the ultrasonic probes used in ultrasonic equipment and instruments use the same signal output mode as the transmitting and receiving chips. The common problem is that the resistance to interference signals is poor in the process of signal output, transmission and amplification. [0003] The Chinese patent authorization announcement number is CN201110843Y, and the utility model patent with the authorization announcement date on September 3, 2008 discloses a detection device used in the detection of bolt fatigue cracks, especially a kind of ultrasonic detection of fatigue cracks in the thread root of non-disintegrating bolt...
