一、利用原有气动控制器的传感器1.1 限位开关是通常所谓的微型开关或测微开关。是以电器设备中的限位开关形式制成的。这种方法多数用于以触点方式检测工件是否存在等场合。1.2 气动测微器过去的气动技术要直接利用气动测微器的测量信号是有困难的。多数是用于膜片式的控制线路。而射流元件在有微压信号(50毫米水柱)输入时就可能切换,因而气动测微器容易 First, the use of the original pneumatic sensor sensor 1.1 limit switch is usually the so-called micro switch or micrometer switch. Is based on electrical equipment in the form of limit switch made. Most of this method is used to detect the existence of the workpiece and other occasions. 1.2 Pneumatic micrometer past pneumatic technology to directly use the aerodynamic micrometer measurement signal is difficult. Most are used for diaphragm control circuit. The jet components in the micro-pressure signal (50 mm water column) can switch when input, and therefore easy to aerodynamic micrometer
