Revealing The Secret Of Rf Admittance Type Level Switch: Technical Principles And Characteristics

rf admittance type level switch measurement principle:

As a new level control technology, radio frequency admittance is derived from capacitive technology and has higher reliability, more accurate measurement results and wider applicability. The radio frequency admittance level meter uses high-frequency radio waves for admittance measurement, which combines resistive, capacitive and inductive components, and achieves level measurement by measuring the admittance value formed by the medium and the sensor. As the material level changes, the admittance value also changes accordingly, and the circuit unit converts the measured admittance value into a material level signal and outputs it. Compared with traditional capacitive technology, radio frequency admittance material level switch technology is different in continuous measurement, and adds two important circuits, oscillator buffer and AC conversion chopper driver, to solve the problem of connecting cables and vertical There is a problem with material hanging at the root of the sensor when installing it.

Features:

Strong versatility: it can measure liquid level and material level, is suitable for different temperatures, pressures, and media, and can be used in harsh environments such as corrosion and impact.

Anti-sticking: The unique circuit design and sensor structure prevents the sensor from being affected by stuck materials. The radio frequency admittance level switch does not require regular cleaning to avoid mis-measurements.

Maintenance-free: There are no moving parts in the measurement process to avoid damage to mechanical parts and no maintenance is required.

Anti-interference: The contact measurement of rf admittance type level switch has strong anti-interference ability and can overcome the influence of steam, foam and stirring on measurement.

Accurate and reliable: Diversified measurement quantities make the measurement more accurate, not affected by environmental changes, high stability, and long service life.
