RF Admittance Level Switch
RF Admittance level sensor uses a rod probe and RF source to measures the change in admittance. The probe is driven through a shielded coaxial cable to eliminate the effects of changing cable capacitance to ground. When the level changes around the probe, a corresponding change in the di-electric is observed. This changes the admittance of this imperfect capacitor and this change is measured to detect change of level.
