The level detection equipment designed using radio frequency admittance technology is an upgraded product of capacitive level technology. It detects changes in the medium through a capacitor consisting of a probe and a container wall, measures changes in admittance values using high-frequency radio waves, and adds an oscillator buffer and an AC converter chopper driver to solve the problem of sensor hanging. This device adopts a modular design, including a main electrode and a compensation electrode, which can measure the comprehensive changes of capacitance, resistance, and inductance, and has anti hanging and anti-interference characteristics. The probe has a temperature resistance range of -20 ℃ to 200 ℃, a protection level of IP66, and supports vertical installation and split structure. Suitable for level detection of liquids, slurries, powders, and granular materials, widely used in industries such as chemical, power, metallurgy, and food, covering monitoring of materials such as petroleum, cement, and grains
