Split type Al. alloy junction box high temperature RF admittance level switch
Split type Al. alloy junction box high temperature RF admittance level switch develops from the technology of capacitor level measurement. It is a kind of level control technology that features hanging resistant, more reliable, more accurate and more wider application. The admittance in RF admittance means reciprocal of resistance from electricity perspective. It consists of resistance, capacitance and inductance, while RF refers to emitting high frequency of radio. Therefore, RF admittance level sensor technology accomplishes the level measurement by using high frequency of radio to measure the measured medium admittance. The most important difference between RF admittance technology and capacitance technology is the measurement's diversity as well as three-electrode technology. The measurement's diversity that is measured by RF admittance not only includes capacitance measurement but also resistance and inductance values measurement, which ensures an accurate measurement. Three-electrode technology includes electronic unit and sensor unit. The shield electrode is added between the measuring electrode and ground pole to prevent the measuring electrode from being influenced by the hanging material.
