NYDR radio frequency capacitance level meter adopts Radio Frequency (RF) Capacitor Technology , when the detection probe contacts the medium Capacitance shift due to dielectric constant change , to achieve accurate liquid level measurement. Modular integrated design, no moving parts, strong anti-interference It is suitable for continuous liquid level monitoring in complex working conditions such as corrosive liquids, high temperature and high pressure.
How it works The working principle of the RF capacitance level meter is based on radio frequency (RF) capacitance technology. A radio frequency is applied to the probe, and the influence of the surrounding environment is determined through continuous analysis. Because all materials have a dielectric constant and their conductivity is different from that of air, when the probe contacts the material, the total impedance reflected by the small capacitance offset changes. Because the energized probe and the container wall form the two plates of the capacitor, the insulator of the probe and the surrounding air become the dielectric material. When the air (dielectric constant is 1.0) is replaced by any other material (dielectric constant>1.0), the change in capacitance value causes a change in impedance. This effect is measured by the circuit and compared with the reference benchmark established by the sensitivity setting (circuit). Design Principle The modular converter is integrated with the sensor, has no moving parts, has high reliability and strong anti-interference ability; Wider applicability, with multiple probe forms, multiple process connection forms, multiple manufacturing materials, and customizable designs; Installation, debugging and maintenance are extremely convenient. Product Model Product Selection Usage scenarios Capacitive level gauges can be used for continuous level measurement of almost all strong and weakly corrosive media and non-corrosive media in open or pressure vessels. They are widely used for level detection and control in industries such as petroleum, chemical industry, fertilizer, metallurgy, natural gas, power plants, machinery manufacturing, ships, pharmaceutical factories, sewage treatment, food, and wine.
