Product Description

Radio Frequency RF Admittance Level Switch Capacitance Level Switch
Product Description
The measurement principle of RF admittance level switch is: RF admittance is a new level control technology developed from capacitive type, which is anti hanging, more reliable, more accurate and more applicable. It is an upgrade of capacitive level technology. The so-called radio frequency admittance means the reciprocal of impedance in electricity. It is composed of resistive components, capacitive components and inductive components. Radio frequency is the spectrum of high-frequency radio waves. Therefore, radio frequency admittance can be understood as measuring admittance with high-frequency radio waves. When the instrument works, the sensor of the instrument forms admittance value with the irrigation wall and the measured medium. When the material level changes, the admittance value changes accordingly. The circuit unit converts the measured admittance value into material level signal output to realize material level measurement.

Product Features

1.Anti-adhesion: unique circuit design and sensor structure can eliminate the influence of the measurement of the material on the probe, and automatically correct it, avoiding false measurements and signals, and no need to clean the probes regularly;

2.Maintenance-free: The switch can be moved by mistake, no mechanical wear, no maintenance required;

3.Strong anti-interference: contact measurement, 0.3 second delay can eliminate the influence of material fluctuation;

4.Strong adaptability: can detect powder, particles, liquid, viscous, conductive, non-conductive materials.

FAQ
Q: The new magnetic flap liquid level gauge can't show liquid level?
A: 1.check whether there is block in by pass pipe 2.check the the density of medium 3.check whether the float ball is stucked by float ball.

Q: The longest length of magnetic flap liquide level gauge?
A: the length is customized,but in order to be convenient for transport,if the length is over 6m,we recommend

Q: If the float ball is installed at the wrong opposite direction,what's the influence?
A: reading level will be higher than true level,usually higher by length of floatball-70mm

Q: What's installation details of magnetic flap liquid level gauge ?
A: 1.before installation,check specification with label plate. 2.There shouldn't magnetic field within 400m

Q: There is problem in output signal 4--20mA?
A: 1.Check working power supply 2.check wiring 3,check load resistance 4.verify measuring range,zero point

Q: what's specification we need to know before purchasing magnetic flap liquid level gauge?
A: medium density,working temperature,working pressure,material,flange center to center distance,flange standard,whether need 4--20mA output signal;wether need level alarm
