The DRFK-98 series RF admittance level switch is a universal point level control instrument. It comprises an electronic module, an explosion-proof housing, and a rod or cable style sensor. Equipped with a synchronously driven auxiliary probe, the unit eliminates measurement errors caused by material build-up.
Featuring stable and reliable performance and great versatility, the device is maintenance-free. Its measurement is unaffected by material density, particle size, chemical composition, conductivity, high temperature or high pressure.
It is widely used for process control of liquids, solids, liquid interfaces, foam, slurries, powders and granular materials across diverse industrial applications.
