1.  General comment

A measuring point consists of the following components:

 

Transmitter unit

 

Receiver unit

 

2 x lock nut for locking transmitter and receiver unit

 

G-1½“-socket for mounting the unit

2.   Function

The ProGap 2.0 is a non-contact microwave barrier. The sensor can be used on metallic and non-metallic 
pipes, tanks, manholes, bellows, etc. The microwave measure through non-conductive materials, such as 
plastics, glass, etc. This makes it possible to detect with the sensor from the outside or through a window. 
In this way, the measurement can be completely decoupled from the process. For example to measure 
aggressive, abrasive or lumpy materials. 
Various process adapters can be used to solve applications with temperatures up to 1000 °C, pressure up to 
20 bar and all Dust-Ex-Zones. The maximum distance to be monitored between sender and receiver is 25 m.
