RF Type Level Switch


Brand Sunflow
Model SF/RFL/401
Application Cements Industries

A Reliable Level Switch Based on Radio Frequency principle for Solids, Liquids, Slurries. S RF Level Switch comprises of an electronic controller, a sensing probe and coaxial cable for the connection of the electronic controller to the probe. The Electronic Controller provides RF signals to the probe and measures the changes in parameters provided by the sensing probe mounted in the material (to be measured) container. The sensing probe does not contain any electronics.

Electronic Controller (SF/RFL/401)

Electronic Controller contains electronics housed in a Dust/Weather proof enclosure and it is mounted separately at a convenient location remote from sensing probe.
