Overview

The DL-LRSP RF admittance switch emits a certain amount of high-frequency radio waves that act on the probe. Analyze and determine the changes in the level of the container based on this. The radio frequency admittance switch changes the frequency of radio waves depending on the material being tested. The probe of the RF admittance switch and the container wall form a fixed distance two-stage capacitor, and the insulation material of the probe and the surrounding air provide insulation medium; When air is replaced by other media, the capacitance between the probe and the container wall will change, which will cause a change in the radio waves acting on the RF admittance switch probe. This change was detected by the internal circuit of the RF admittance switch

Measurement principle DL-LRSP

The RF admittance switch emits a certain amount of high-frequency radio waves to act on the probe. Analyze and determine the changes in the level of the container based on this. The radio frequency admittance switch changes the frequency of radio waves depending on the material being tested. The probe of the RF admittance switch and the container wall form a fixed distance two-stage capacitor, and the insulation material of the probe and the surrounding air provide insulation medium; When air is replaced by other media, the capacitance between the probe and the container wall will change, which will cause a change in the radio waves acting on the RF admittance switch probe. This change is detected by the internal circuit of the RF admittance switch and compared with the set value to determine its amount of change. When it is the same as the set value, output a switch signal

Technical Advantage DL-LRSP

edit

The RF capacitance sensor of the RF admittance switch can provide economical and reliable point control. The probe of the RF admittance switch can be applied to dust and solid particulate matter, and can provide high sensitivity, stability, and durability, with equally excellent results for liquids and mud.

Application scenarios

Edit DL-LRSP

Radio frequency admittance switches are widely used, with several typical applications including chemical and plastic film; Feed/grain rubber drugs; Liquid wastewater sand; Food slurry cement; Powder coating/clothing coal; Granular solid oil pulp, etc.

feature

Edit DL-LRSP

Strong universality: It can measure liquid and material levels, meet the measurement requirements of different temperatures, pressures, and media, and can be applied to harsh environments such as corrosion and impact

Anti hanging material: The unique circuit design and sensor structure enable its measurement to be unaffected by sensor hanging material, without the need for regular cleaning, avoiding false measurements.

Maintenance free: There are no movable parts during the measurement process, and there is no mechanical component damage issue, so no maintenance is required.

Anti interference: contact measurement, strong anti-interference ability, can overcome the influence of steam, foam and agitation on measurement.

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