Purpose: To enable measurement of powdered and granular products when the flow is discontinuous or product density is minimal.
The product loss sensor detects the absence of product so that measurements are not updated until product reappears under the gauge. Only necessary when product is discontinuous, or there are frequent lulls in the production stream.
Description: A photocell is attached to the light tube. The output from this device is used to "gate" the sensor.
Connection: The product loss sensor is through the main board in the gauge, and provide a contact closure input to the input/output board.
