H-type speed sensor
Mainly used for coal mine monitoring When the underground belt conveyor is transported up or down due to belt slippage (stall) or overspeed, the belt conveyor should be monitored and protected. Fix the magnet to the end face of the driven wheel, fix the speed sensor to the frame, and keep the sensing end close to the magnet. After the belt conveyor is running normally, just press the calibration button. % />
Install the magnet on the end face of the driven wheel of the belt conveyor and rotate with the driven wheel. When the speed sensor is close to the magnet, the magnetic sensitive element of the speed sensor generates a positive pulse signal that is proportional to the speed of the driven wheel. , each positive pulse triggers the monostable circuit, and after reversal, a positive pulse with a certain pulse width is generated. At this time, the positive pulse and the positive pulse emitted by the magnetic sensor are input into another monostable circuit at the same time. When the speed is normal, these two pulses are input into the monostable circuit at the same time. After conversion, the speed end outputs a high level. If the belt slips and the speed of the driven wheel decreases, the positive pulse emitted by the magnetic sensor element will not be synchronized with the positive pulse triggered by the previous pulse. , after a period of delay, the speed end of the speed sensor outputs a low level, the stall indicator light turns on, the host executes the relay release, cuts off the belt conveyor control power supply, realizes low-speed protection, and issues a verbal alarm at the same time. The pulse width of the monostable circuit can be changed by flipping the switch, so that the speed can be adjusted in ~ rpm.
