RF admittance level switch for measuring silo dust
The structure of the Admittance type level sensor is divided into two parts: the main electrode and the compensation electrode. Applying a set of RF RF signals between the main electrode and the compensation electrode respectively, it has excellent anti sticking and hanging characteristics, and is a new type of material/liquid level measurement product that replaces capacitive level switches.
Description
Technical Parameter
Product Introduction:
Admittance type level sensor (RF admittance level gauge) is an instrument used to measure the height of materials such as liquids, granules or powders. It uses radio frequency admittance (Admittance) technology to determine the liquid level or interface of the material by measuring the admittance (including conductivity and capacitance) between the material and the sensor.
It works by emitting radio frequency signals to sensors installed in the container. When material comes into contact with the sensor, the signal is affected, causing the signal received by the sensor to change. By measuring these changes, the radio frequency admittance level meter can accurately measure the height of the material.
It is a liquid level measuring instrument with high precision, strong anti-interference ability and wide application range. It is widely used in petroleum, chemical industry, metallurgy, food and other industrial fields.
Product Features
Working principle
The Admittance type level sensor is based on radio frequency (RF) capacitor technology. Apply a radio frequency to the probe and determine the impact caused by the surrounding environment through continuous analysis. The energized probe and the container wall form the two electrode plates of the capacitor. The insulation of the probe and the surrounding air become dielectric materials, and all materials have a dielectric constant. The Admittance type level sensor dielectric constant is greater than that of air. When air is replaced by any other material, the capacitance effect is strengthened, thereby changing the impedance of the application, that is, the change in capacitance value causes the impedance to change. After this effect is measured by the circuit, it is compared with the reference benchmark established by the sensitivity setting (circuit).
