Material flow sensor

Binmaster A non-intrusive instrument for various material handling applications, Flow Detect 2000 prevents downtime caused by blockage, conveyors running empty, no material flow to-and-from a process, or loose slide gates that can cause production loss and equipment failure. The microwave-based instrument tracks flow conditions of powders and granules in gravity chutes, feeders, pipelines, conveyor belts, or bucket elevators.

The Flow Detect 2000 contains the sensing element, power and output connections, and user adjustment controls in a single NEMA 4X enclosure. The sensor does not come into contact with the flow stream, eliminating the risk of wear. It uses microwave Doppler technology for highly sensitive motion detection. The high frequency, low power microwaves are able to pass through non-metallic materials. A switchable filter incorporated into the signal path of the Doppler output reduces the effect of vibration. This filter also ensures the detection of moderate and fast-flowing materials.
The Flow Detect 2000 provides a single analog relay output to communicate flow or no flow status to a PLC. Both normally open (NO) and normally closed (NC) contacts are available. LED indicator lights for power, flow/no flow and fault conditions show the status of the device. Controls for adjusting sensitivity and the output delays are used during the initial setup.
