Product Description

Product Introduction:

 

1.The working principle of radio frequency admittance level switch 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. Due to the fact that all materials have a dielectric constant and their conductivity is different from that of air, the total impedance reflected by the small capacitance offset changes when the probe comes into contact with the material. Because the energized probe and the container wall form the two plates of the capacitor, the insulation of the probe and the surrounding air become dielectric materials. When the air (with a dielectric constant of 1.0) is replaced by any other material (with a dielectric constant>1), the capacitance effect is strengthened. This changes the impedance of the application. The change in capacitance value causes a change in impedance. After this influence is measured by the circuit, it is compared with the reference benchmark established by the sensitivity setting (circuit).

2.Setting the sensitivity of the RF admittance level switch correctly will affect the correct change in sensor output. The Null KoTeTM circuit of the probe can make the measurement circuit ignore the accumulation of materials on the probe, otherwise it will cause sensitivity failure. The Null KoTeTM circuit is excited using the same radio frequency potential as the sensor probe. Due to the inability of current to flow at the same potential, the NuIl KoTeTM circuit isolates the flow of current from the energized probe through the stacked material to the container wall. This measures the material around the energized probe, not the accumulated material.

 

Detection principle:
 

1.The SP type electronic circuit adopts an anti adhesion circuit, which can remove the influence of adhesion and false object level signals hanging around the probe while detecting the real object level.

2.The SP type can detect the presence (high position) or absence (low position) of materials in various containers based on the working principle of ash storage sensing.

3.Fault alarms can be set for high or low mode.

4.The SP type can detect any process material, such as refined oil, gasoline, conductive mud, etc.

5.The SP type and L86X type sensing probes are matched.

6.The SP type and L86X type sensing probes are matched. L863C is a universal probe, L890C is a flat probe and also provides a steel rope probe. It has stainless steel structure and can be used in high temperature and high pressure environments, liquids, powders, large solid blocks, and corrosive objects.

 

Design features:
 

1.Strong universality: can be applied to the measurement of various conductive and non-conductive media, such as liquids, viscous substances, particles, powders, fly ash;

2.Anti adhesion: Adopting a patented anti adhesion circuit, it can eliminate false signals caused by material adhesion;

3.Probe detachable: There is no cable connection between the controller and the probe, and the controller can be removed, replaced, and repaired at any time without affecting the entry and exit of materials;

4.High and low temperature resistance: suitable for working environments ranging from -184 ° C to 280 ° C, and ceramic probes suitable for higher temperatures can also be provided;

5.Output form: Adopting a double pole double throw relay signal output, with a status light displaying the output status and a delay function of 0 to 30 seconds.
