这种电子速度继电器用于工业的自动控制,它用无接触传感器组成检测头,控制器由集成电路和少量外围元件组成。型号有单限速、双限速、上下限速三种。单限速又可分欠速型和过速型两种。其鉴别转速精度高达0.1％;适应速度范围从每分钟半转到上万转。它既可装在任何有极限转速要求的机 The electronic speed relay for industrial automation, which uses a contactless sensor head, the controller consists of integrated circuits and a small amount of peripheral components. Model has a single speed limit, double speed limit, upper and lower speed limit three. Single speed and can be divided into two types of speed and over speed. The differential speed accuracy of up to 0.1%; Adaptation speed range from half a minute to tens of thousands of turn. It can be installed on any machine with the required speed limit
