Working Principle

RF Admittance Level Switch is developed based on the introduced RF technology, which is anti-adhesive, more reliable and extensively used. With high frequency radio waves applied to the probe, the conductance value formed together by the probe, the admittance wall and the measured materials changes accordingly when the position of the material changes. Once the electric circuit detects this change, the analyzing and processing unit of the instruments makes constant analysis to recognize the change of the surrounding environment (material level), and then converts this change into related output signals for long-distance control or alarm. The unique electric circuit design based on the equipotential principle enables the measured circuit to eliminate any impact on detection by the material adhering on the probe, thus correctly reflecting the actual material level rather than the accumulated materials that adhere on the probe.


Product Advantages

Wide Application: Application for the detection on flying ash, particles,powders, liquids, and adhesive, conductive or non-conductive materials.

Anti-adhesion: Unique electric circuit design to enable the measuring circuit to neglect the accumulated materials on the probe and conduct automatic readjustment.

Separate Probe: Separable probe and controller without cable connection to facilitate disassembly, and installation without influence on the work site.

Powerful Function: Huge output contact capacity with a indicator to show the work status and 0 to 30 seconds time delay to eliminate the influences from the medium’s fluctuation.

Power-off Protection: Normally open or normally close (which can be switched on site)
