利用本传感器能够检测到从泄漏的流体以及产生机械摩损的部位发出的超声波信息,并将此种信息变为音响报警声或通过仪表指示出来。因此这是一种探测故障部位的超声探测器之一。它是由超声特种集音部分和放大器组成,可以探知35kHz～45kHz的超声波段,并使所测信号变为音频信号,广泛地应用于飞机维修工作的各种检查和管路检测上。其使用方法大致如下所述:1.采用广角和窄角集音器,可以测得冷气以及燃气等的泄漏声,从而测定其泄漏部位。2.把接触探测器贴在机件外壳上或系
This sensor detects ultrasonic signals from leaked fluid and parts that cause mechanical wear and changes this information into audible alarm sounds or through instrumentation. So this is one of the ultrasound probes to detect the fault location. It is composed of ultrasonic special sound collecting part and amplifier, which can detect the ultrasonic frequency range from 35kHz to 45kHz and make the measured signal into an audio signal. It is widely used in various inspection and pipeline testing of aircraft maintenance work. The use of the method is described as follows: 1. Using wide-angle and narrow-angle sound collector, you can measure the air-conditioning and gas leaks, etc., to determine the leak site. 2. The contact detector attached to the mechanical shell or Department
