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.
