Microwave sensors from WADECO are being employed for multiple industrial applications such as blocked chute detection, flow/ no flow detection and product detection in conveyors among others.  

WADECO is exclusively represented in Australia by Semrad .  

In addition to level detection, microwave technology is increasingly being used for various detection applications in industry.  

Microwave technology can also be used in the detection of blocked pneumatic conveying pipes and blocked air slides.  

WADECO MWS-ST/SR type microwave sensors are switches that consist 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.  

MWS-ST/SR microwave sensors have non-invasive installation methods and there is no disruption to material flow, allowing the process to be kept closed. The microwave sensors are also unaffected by build-up on the antenna head, thanks to the high penetrability of microwaves.  

With the new Series 3 microwave sensors, the range can now extend up to 200 metres, making them ideal for situations where high power is required for blocked chutes or long range anti-collision applications.  

Key features include:

  • Withstands rough environmental conditions including heavy dust, airborne particles, smoke, vapour, flames, rain and snow
  • Wide application across all areas of industry where highly reliable, non-contact detection is required
  • Generally used for process control by monitoring presence or absence of product, flow/ no flow conditions as well as point level detection in bins and silos
  • No moving parts and non-contact detection result in reduced wear and tear, zero maintenance and added safety for personnel and operators

Semrad is a leading Australian distributor of level switches and transmitters, designed specifically for harsh industrial applications. Their broad range of sensing technologies provides complete application coverage with superior user flexibility.
