Non-invasive microwave level switch for blockage detection
The Hycontrol range of microwave level switches provides a simple non-contact, non-intrusive option suitable for many applications on dry powder or granular product.
An installation comprises a transmitter and a receiver which are mounted facing one another at distances up to a maximum of 100m apart (for the AC version). During operation the transmitter emits a continuous, low power, microwave beam to the receiver and an output relay is energised or de-energised when this beam is obstructed by the material being monitored.
The switch trigger point is determined by the amount of microwave energy received and can, therefore, be adjusted to cater for different products and different sensitivity settings depending upon the application.
Typical applications for detecting presence and non-presence of materials include flow and no-flow conditions, point level detection, blocked chute detection and also proximity switch detection for reversing vehicles including trucks and rail cars.
The advantage of this technology is that it is able to monitor through product build up on tank or chute walls and can be non-intrusive by utilising protective windows as shown above right.
This technology is ideal for replacing costly nucleonic devices.
