Shiva electronics provides a new photoelectric sensor. This hopper-level sensor is used for hopper-level control. Sensing range is 100 to 600 mm. Invisible infrared light beam is used by the sensor to determine the distance to the top level, and can reliably maintain sufficient material in the hopper by controlling the inlet valve, this sensor is available in m36 brass chrome-plated housing and works off 12v dc or 24v dc.
