Use / Function

The ProGap 2.0 microwave barrier is a universal sensor with a flexible range of applications, consisting of a transmitter and receiver on the basis of the latest microwave technology. It is used to detect the limit level of dry bulk solids of all types or to position objects.
The microwave barrier is a contactless measuring procedure.
It can be installed in containers, pipelines, shafts or free-fall sections. The range is 0.1 ... 25 m . Larger ranges can also be realised. If container walls, housings or pipelines are not metal, it is possible to measure from the outside. This even makes it possible to completely uncouple the measurement from the process through suitable windows made of non-metallic materials. This is especially interesting in the use of aggressive, abrasive or coarse materials or in cases of extreme pressures and temperatures. The ProGap 2.0 can also be used under difficult conditions such as high operating temperatures and pressures with the help of a process-adapter. The use of microwaves also ensures a high level of insensitivity to any caking on the sensor window.

Mounting and Installation

The transmitter and receiver are installed by screwing into a  G 1 ½" threaded connection. 
The device can be installed at any installation height.
It is important that the transmitter and receiver have the same installation height. The adjustment takes place with the help of a counter-threaded connection. 
A display of the signal intensity facilitates the adjustment. The connection to the power supply takes place on the transmitter and the receiver.
The switch output is made available on the receiver. No additional analysis unit is necessary.
