Semrad has launched the WADECO MWS-ST/SR type microwave sensor for blocked chute and pipe detection.
The switch consists of a transmitter (MWS-ST) and a receiver (MWS-SR) installed face to face.
The transmitter emits a continual low power microwave beam towards the receiver and an output relay is released when the beam is obstructed.
It can be used for applications such as the detection of blocked chutes, flow/no flow detection, for products on conveyors, as well as the detection of blocked pneumatic conveying pipes and of blocked air slides.
The sensor has a completely non invasive installation, meaning there is no disruption to material flow and allows the process to remain closed.
It is unaffected by material build up on the antenna head, and now comes with a range of up to 200 metres.
With no moving parts and non contact detection, the sensor has reduced wear and tear, and zero maintenance.
