美国研制出了一种叫做SC—30的车辆空气制动系统泄漏探测仪,仪器上装有超声波传感器,它可以将空气泄漏时产生的超声波转换成电信号,然后自动完成记录、在泄漏处打印痕迹和编排检修顺序等一系列过程,它可以和热轴检测器联接起来一起使用,也可以和计算机及报警装置联接起来。由于它只能感受超声波,所以在外界杂音很大的环境中仍然可以准确地进行探测。 The United States has developed a vehicle air brake system leak detector called the SC-30, which is equipped with an ultrasonic sensor that converts ultrasonic waves generated when air leaks into electrical signals and then automatically records and prints traces of leaks And scheduling a series of maintenance procedures, which can be used together with the hot shaft detector together, but also can be connected with the computer and alarm devices. Because it can only sense the ultrasound, it can still be accurately detected in a very loud environment.
