As well as its use for level detection, microwave technology is now being applied across many industries for applications such as the detection of blocked chutes, flow/no-flow detection, the detection of product on conveyors, the detection of blocked pneumatic conveying pipes and the detection of blocked air slides.
The Wadeco MWS-ST/SR-type microwave sensor is a switch consisting of a transmitter (MWS-ST) and a receiver (MWS-SR) installed face to face. The transmitter emits a continuous, low-power microwave beam towards the receiver and an output relay is released when the beam is obstructed.
With the microwave sensor’s non-invasive installation methods, there is no disruption to material flow and the process can be kept closed. Microwave sensors are also unaffected by build-up on the antenna head, due to the high penetrability of microwaves. With the series 3, the range can now extend up to 200 m.
Microwave sensors are also unaffected by environmental conditions including heavy dust and airborne particles, smoke, vapour, flames, rain, snow etc.
Microwave sensors have a wide application across all areas of industry where highly reliable, non-contact detection is required. They are generally used for process control by monitoring presence/absence of product, flow/no flow conditions and point-level detection in bins and silos.
With no moving parts and non-contact detection, the result is reduced wear and tear, zero maintenance and added safety for personnel and operators.
