Hawk's microwave beam blockage detector is designed for blocked chute detection in bulk material conveying

Hawk introduces the next generation of microwave beam blockage detectors. The system uses microwave energy to detect blockage between a sender and a receiver. The system is designed for blocked chute detection in bulk material conveying and transfer systems, solving the costly problems of false tripping and failure to respond. Other areas of application are boom collision detection, nucleonic switch replacement and point level switching for most solid and liquid materials, including wet, dry and bulk material.

The complete system includes two functions: a sender and a receiver. The sender transmits rapid bursts of microwave energy. The matching receiver is positioned in line with the sender. If the beam path is blocked by any object or material, the receiver will not be able to detect the signal. The presence or the absence of the signal at the receiver is used to switch a relay for indication or for control purposes. The receiver may be mounted up to 100 meters (328 feet) from the sender. The sensitivity of the detector is adjustable, allowing the system to tolerate build-up or changes in material properties.

It is not necessary for the sender or the receiver to contact the material being sensed. Microwave energy can penetrate plastic tanks or pipes, or windows made of glass, UHMW, PTFE, firebrick and some ceramic materials.

Systems can be configured as remote — where a controller drives the sender and receiver —  or integral — stand-alone sender and receiver — depending on user requirements and access to sensing positions.
