Non-contact point level detection in solids with free space radar sensors
In many cases where contact methods are limited, microwave barriers are the appropriate solution. Soliwave devices avoid jamming, indicate point levels, solve positioning and counting tasks, provide non-contact measurement and are thus, free of wear and tear. Typical products to be measured are wood chips, paper and carton chips, lime, pebbles, sand or even bags and complete boxes.
The microwave barrier uses a contact-free procedure for detection of point levels. It can be installed in containers, conduits, shafts or on free fall shafts. It is possible to take a measurement through non-metallic container materials from the outside. Soliwave is suitable as point level switch for controlling and counting all types of bulk solids. Emitter and receiver interact with each other.
Microwave barrier measurement: Measuring Principle
Microwave barriers are used to detect all kind of bulk solids based on microwaves (transmitter/receiver-principle). The detection of bulk solids movement (present / not present) is based on the Doppler effect of the microwaves.
Non-invasive - tanks penetrated by microwaves from outside
Measuring principle almost unaffected by process conditions
Mechanical robust solution - maintenance free
