Separate underspeed slip switch MYDH-SF2
Overview;
The underspeed slip switch is a reliable, simple and universal monitoring device for shaft speed and other rotating devices. When it is detected that the current speed signal is lower than the normal speed range, the switch outputs a switch signal for alarm or shutdown. No moving parts, no wear, long safety life, integrated structure, centralized control device, easy to set or troubleshoot。
instalación:
The underspeed slip switch is installed on the side of the conveyor driven wheel or other shaft that can be equal to the actual speed of the belt. The side of the driven wheel or the rotating shaft needs to be welded with a sensing surface for the under-speed slip switch (the sensing surface must be made of iron material), the section size of the sensing surface is not less than 50mm×50mm, and the maximum distance between the under-speed slip switch and the sensing surface is 25mm. The sensing surface provides a pulse signal for the under-speed slip switch, and the driven wheel rotates a circle and the sensing surface passes through the under-speed slip switch area once to generate a pulse signal. When a pulse signal is generated, the pulse indicator on the under-speed slip switch panel will flash once. It is necessary to ensure that except for the sensing surface, there is no metal object on the side of the driven wheel that can cause the underspeed slip switch to generate pulse signals.

working principle:
The underspeed slip switch is used to detect the rotation speed of the belt conveyor tail wheel, and the switch has no contact with the tail shaft. When the tail shaft rotates with the operation of the belt conveyor, it drives the sensor sheet, and the sensor signal generated by the sensor sheet and the detector is input to the control circuit. After amplifying, shaping and counting, the count value is compared with the preset number to judge the speed of the tape. That is, when the speed is lower than the slip speed, the circuit will output the corresponding switch signal to stop the host. This switch can adjust the speed value.

Preguntas más frecuentes
Q1：Difference between normally closed and normally open tilt switch？
A1：Normally closed is to switch on and off after tilting in vertical state, while normally open is to switch on after switching off tilt in vertical state.
Q2：The difference between manual reset and automatic reset?
A2：Manual reset is to pull the rope switch action to continue to hold after release, need to reset device to restore, automatic reset is pull rope switch action release switch recovery.
Q3：Difference between unidirectional pulling rope and bidirectional pulling rope?
A3：One way is to install the pull rope from one side of the switch, and the other way is to install the pull rope from both sides of the switch.
Q4：Is the action force of pull rope switch adjustable?
A4：The required action force can be informed in advance and can be customized according to the requirements.
