DRFK-98 RF Admittance Level Switch
Introduction
DRFK-98 RF admittance level switch is universal point control meter. he meter consists of a electronic unit, a explosion-proof shell and hard or flexible probe elements. Auxiliary in-phase driven probe should be added through the sensor, which solves the problem of material adhesion.It is stable and reliable, good versatility , no need maintenance. It is not affected by the density of the materials, the size of the particles, the chemical elements, the electrical conductivity, high temperature and high pressure, which can be widely used in the process control of the liquid level or material level of the liquid, solid, slurry and interface.
