The microwave barrier is a contactless measuring procedure
Can be installed in containers, pipelines, shafts or free-fall sections
Range is 0.1 … 25 m

If container walls, housings or pipelines are not metal, it is possible to measure from the outside
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

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.
