rf splitters and combiners.Scope and characteristics of application of radio frequency admittance level gauge

　　Radio frequency admittance is a type of material level control system that has developed and grown from capacitive sensors, which is anti hanging, safer, more reliable, more accurate, and has a wider range of applications. It is a technological upgrade of capacitive sensor material level. As the saying goes, radio frequency admittance refers to the characteristic impedance of a passive network in electricity. It is composed of a combination of resistive, capacitive, and inductive components, and radio frequency refers to the high-frequency electromagnetic spectrum. Therefore, radio frequency admittance can be understood as measuring passive networks using high-frequency electromagnetic waves. When the instrument panel is working, the controller of the instrument panel is connected to the wall and the measured substance, causing a passive network value. When the level changes, the passive network value changes accordingly. The power circuit unit converts the measured admittance value into a level data signal and exports it to achieve level measurement.

　　The radio frequency admittance technology used in the radio frequency admittance level gauge overcomes the problem of the capacitive sensor level switch not being able to remove the influence of conductive hanging materials. Having the following characteristics:

　　1. Radio frequency admittance level gauge has strong universality: suitable for various places, can test particles, fly ash, conductivity, non-conductive liquids, viscous materials;

　　2. RF admittance liquid level meter anti adhesion power supply circuit: The anti adhesion power supply design can remove material adhesion and cause false data signals;

　　3. Power loss safety mode: Low or high fault alarm. Adjustable on the spot.

　　4. The instrument panel at this level operates safely and reliably, with all technical indicators reaching the level of similar international products. It is widely used for alarm and control of liquids, slurries, dust, material levels, and two types of liquid boundaries. In addition, the product has added on-site working status indication, making it a highly cost-effective, stable, safe, and reliable level switch.
