Problems solved by technology
[0002] The photoelectric inductive speed sensor is mainly used on belt scales and batching scales. Its function is to measure the running speed of the belt on the belt scales. Belt scales and batching scales are generally used in coal mines, steel plants, cement plants, coal washing plants, and chemical plants. And other places, these places are dusty, open air, leaking, corrosive, etc., which may easily cause damage to the sensitive element on the photoelectric induction speed sensor—the photoelectric sensor.
The traditional speed sensor has only one photoelectric sensor, once the photoelectric sensor is damaged, the speed sensor will not work normally
At the same time, the existing photoelectric induction speed sensor is exposed and installed outside. Due to the harsh working environment, it will affect the effective contact between the friction roller and the belt on it, thereby affecting the measurement accuracy.
