RF admittance level switch is a development from capacitive level control systems, which is anti hanging, more reliable, and more reliable

　　A more widely applicable level control system, where the meaning of "admittance" in "radio frequency admittance" is the reciprocal of impedance in mechanics,

　　It is composed of a combination of resistive, capacitive, and inductive components, and "radio frequency" refers to high frequency. Therefore, radio frequency admittance technology can

　　The solution is to measure admittance at high frequencies. The output of a high-frequency sine oscillator is a measurement signal source, which uses the principle of an electric bridge to accurately measure the admittance installed on the controller used in the test vessel. In a direct effect mode, the output of the instrument panel increases with the rise of the material level.

　　The difference in technical performance between RF admittance level switches and traditional capacitors depends on the diversity of measurement parameters, the three terminal shielding technology of the driver, and the two key power supply circuits that are improved based on valuable experience. The above technical aspects not only solve the problems of shielding and temperature drift of connecting cables, but also solve the problem of communication and hanging materials for controllers installed vertically. The two power supply circuits that have been improved are high-precision oscillator controllers and communication phase detector samplers. For a vessel made of highly conductive raw materials, since the raw materials are conductive, the grounding point can be considered as the camera in the insulation layer of the probe. For an intelligent transmitter probe, it is only reflected as a pure capacitor. As the vessel is discharged, hanging material is caused on the probe rod, which is resistant. The past pure capacitors have now become complex impedances composed of capacitors and resistors, causing two problems.

　　The RF admittance level switch generates measurement parameters other than capacitors, especially resistor parameters, which increase the frequency stability of the instrument panel measurement data, greatly enhancing the resolution, accuracy, and stability of the instrument panel; The diversity of measurement parameters also fully expands the reliable application fields of instrument panels. The problem is that the raw material itself acts as a capacitor to the camera, which does not consume the kinetic energy of the smart transmitter (pure capacitors do not consume energy). However, if the hanging material contains resistors in the equivalent circuit of the camera, the resistance of the hanging material will consume kinetic energy, which in turn pulls down the oscillator voltage, causing changes in the output of the bridge and resulting in data errors. We have added a controller between the oscillator and the bridge to supplement the kinetic energy of Shore, thus measuring the oscillation voltage applied to the camera.
