ENVEA - Model ProGap 2.0-BS - Point Level Monitoring Microwave Barrier
From Process Optimization - Level Monitoring
Microwave barrier for contactless detection of dry bulk solids with filling-signal-suppression.
Features & Benefits
- Absolutely insensitive to material caking
- Can be used up to a profile of 25 m (larger profiles on request)
- Can be used with adapter up to 220 °C and 20 bar
- With ceramic mounting, usable up to 1,000 °C
- Usable in dust EX-zones by using a process adapter
- Signalling through relay switching
- Detection through non-conductive walls
- Extra short sensor with separate analysis unit
- No measurement failure because of strong material flow for filling
Main Applications
- Limestone
- Tiling
- Waste incineration
- Cement
- Building materials
Technical Specifications
- Material to measure: Dust, powders or granulates
- Working principle: Microwave
- Silo diamter/ detection range: 25m
- Process pressure: Max. 20 bar
- Process temperature: Up to 1000°C
- Mounting: 1 1/2 ” threat connection
- Place to measure: Silos, containers, chutes, pipelines, transition points

Technical Data
- 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

Mounting & Installation
The ProGap S can be easily installed in the following ways:
- screwing into a G 1½-inch-screw neck
- with an DN-40-flange or
- with a clamp or other mounting
The fitting position of the devices is arbitrary. Important is that transmitter and receiver are positioned precisely to each other. The adjustment is made by means of a counter-screw fitting. Commissioning will be done by evaluation unit.
