RF admittance level switch

RF admittance level switch is widely used in petroleum, chemical, metallurgy, electric power, medicine, food, paper, building materials and other industrial fields. The product uses high-frequency technology to generate a low-power RF signal from the electronic circuit to the probe, which acts as a sensitive element to feed back the signal change caused by the dielectric constant of the material level to the electronic circuit; these Change the output state of the relay after processing. It is an improvement of RF admittance measurement technology on the basis of the original capacitance measurement, which represents the new level of level measurement.

Typical applications of RF admittance level switch:

Liquid: conductive liquid and insulating liquid (including liquefied gas)

Paste: conductive paste and insulating paste

Particles: grain, plastic sheet, coal, etc

Interface: two kinds of liquid interface with different dielectric constant

Powder: plastic powder, cement, fly ash, etc

Characteristics of RF admittance level switch:

It can measure liquid level and material level to meet the measurement requirements of different temperature, pressure and medium.

It is not affected by the sensor hanging, and does not need to be cleaned regularly to avoid wrong measurement.

There are no movable parts and mechanical parts damaged during the measurement.

No maintenance and no adjustment.

Contact measurement has strong anti-interference ability, and can overcome the influence of steam, foam and stirring on measurement.

The measurement quantity is diversified, which makes the measurement more accurate, the measurement is not affected by environmental changes, and the stability is high.

The product has reliable performance and long service life.

Simple calibration, easy installation and beautiful appearance;

Product performance is stable;

Anti adhesion (hanging material);

All kinds of models have strong versatility and wide applicability;

It can be used with PLC or DCS to realize automatic detection and control of process flow.
