Speed monitor

Function and appearance

The sensor has an integrated integrated speed monitoring function: there are pulse recognition, detection, and processor in the same shell, and the ability to output, convert, drive and amplify the pulse signal at the same time; the shape can be seen in the following figure: its shell is mainly It is composed of a copper shell with a diameter of 30mm and a length of 72mm (thread part 65mm, 7mm at the label) and a plastic head of 1mm thickness and a plastic tail of 6mm thickness (with an action indicator and a potentiometer to adjust the speed); with speed monitoring sensitivity High, 

easy to use, waterproof, anti-fouling and other effects.

Working principle

The sensor uses the tail speed adjustment potentiometer to preset the frequency ft (speed). When the moving parts (mainly iron, copper, etc.) to be monitored rotate at a certain frequency fc (speed) 

within 10 mm from the sensor head, the sensor Corresponding pulse signals are generated internally through magnetic induction and input into the control circuit. After the circuit is amplified 

and shaped, the count is performed; then the count value obtained is the rotation frequency fc (speed) of the moving part to be monitored and the preset frequency ft (speed )Compare. If fc> ft, 

then the sensor generates a signal to cause the switch or relay to close; if fc<ft, then="" the="" sensor="" generates="" another="" signal="" to="" cause="" switch="" or="" relay="" open;<="" p=""></ft,>

Instructions for use

The sensor is activated for 9 seconds (switch or relay closed state) immediately after poweron to allow the monitored object to have a starting process. After the delay start, if the action 

indicator at the end of the sensor does not light, it means that the rotation frequency (speed) of the 

monitored object is lower than the preset frequency (speed) of the sensor, then the sensor or relay is in the disconnected state. The potentiometer that adjusts the speed of the tail slowly rotates the 

adjustment screw counterclockwise to make the action indicator light, and the sensor or relay is closed; on the contrary, after the delay start, the action indicator light at the end of the sensor is 

always on, indicating that the monitored object rotates If the frequency (rotation speed) is higher than the preset frequency (rotation speed) of the sensor, then the sensor or relay is in the closed state. At this time, the potentiometer at the rear of the sensor that adjusts the rotation speed can be slowly rotated clockwise to make the action indicator light off. , The sensor or relay is off again.

Usually in actual use, if the sensor or relay is in the off state, the preset frequency (speed) of the sensor is set to 80% of the rotation frequency (speed) of the monitored object during normal operation.
