6m RF Admittance Level Transmitter Rod Type Level Transmitter Hard Insulating

NYSP-Z23 Rf Admittance Level Meter​

The NYSP-Z23 Rf admittance is a new level control technology developed from capacitive, which is more reliable, more accurate and more widely applicable. It is an upgrade of capacitive level technology. The so-called rf admittance means the reciprocal of impedance in electricity, which is composed of resistive components, capacitive components and perceptual components. Rf is high-frequency radio spectrum, so rf admittance can be understood as the measurement of admittance with high-frequency radio waves. When the instrument is working, the sensor of the instrument forms an admittance value with the perfusion wall and the measured medium. When the object level changes, the admittance value changes accordingly. The circuit unit converts the measured admittance value into the object level signal output to realize the object level measurement.

Rf Admittance Level Meter Operating Principle

Traditional capacitive material level meter, with the level rising, material covered probes, value of capacitance circuit between the probe and the medium (conductive material) or between the probe and the tube wall capacitance (insulation material) increases.Due to the change of level imbalance led to a capacitance bridge, so the change of capacitance value depends on the dielectric constant of the material being tested.Then through to the signal detection, amplification, and finally the corresponding signal output.Capacitive material level meter, however, there are some disadvantages, especially when the probe is hanging will seriously affect the measurement result.

Radio frequency admittance measurement technology is level measurement technology has unique advantages.Although with the general concept of capacitance measurement technology are similar, but the rf admittance technology in electronic unit joined the Driving - shields and chopping circuit, thus can realize impedance and capacitive reactance measurement alone.Through the calculation of the laws of physics, any material is equal to the size of the capacitive reactance of the impedance, so by the hanging can be measured and the influence of by phase-shifting oscillation circuit, remove from the total output.

Rf admittance level meter sensor installed in the loading of the tank, through the probe level change caused by the change of the rf signal.Driving - shields of probe end can prevent radiofrequency current formed by hanging loop, ensure the accuracy of the instrument measurement.

Rf admittance technology of high precision measurement results, and is not affected by the probe hanging, is currently the most widely used occasions a measurement technology.From low temperature to 100 ℃ to 800 ℃ high temperature, from vacuum to 6.3 MPa pressure situations, from ultra short range to large scale, can the normal application, and can be applied to different types of material.
