Weighing machines and weighing coal feeder speed sensor (speed sensor) are used in low-speed optical encoder, high resolution of 600 pulses / rev and 360 pulses / rev to more accurately reflect the true belt speed, accurate measurement, easy to install. Speed ??device is connected to the driven roller soft, fixed and reliable, can truly reflect the belt speed using optical encoder (pulse count), count accurately, not duplicate start and frequency of high and low impact, even in mechanical vibration, self-excited vibration also can maintain stable and electrical noise, throw transfer does not occur.
