Working principle of intelligent RF admittance level meter
2011-10-19 17:25:05

The intelligent RF admittance level meter following the upgrade of the capacitive level technology is a kind of anti-hanging material, higher accuracy, better reliability, and wider applicability developed from the capacitive level gauge. New control technology.

即是利用射频导纳,导纳的含义为电学中阻抗的倒数。 The so-called radio frequency admittance level meter uses radio frequency admittance, and the meaning of admittance is the inverse of impedance in electricity. It is a combination of capacitive, resistive and inductive components. High frequency radio spectrum is radio frequency, and radio frequency admittance is measured by high frequency radio waves.

    The difference between the RF admittance technology and the traditional capacitor technology is that the RF admittance technology adds two circuits of an AC converter chopper driver and an oscillator buffer according to the findings in the practice of conducting materials. 1 )解决了连接电缆问题;( 2 )解决了垂直安装的传感器根部挂料问题; The addition of two very important circuits ( 1 ) solves the problem of connecting cables; ( 2 ) solves the problem of hanging materials at the root of the vertically installed sensor;

的传感器与灌壁,形成被测量介质的导纳数值。 The sensor and the wall of the intelligent RF admittance level meter form the admittance value of the measured medium. When the instrument measures the level change, the measurement admittance value is converted into an output signal by the unit circuit, and the corresponding admittance value of the level measurement also changes accordingly, achieving the purpose of accurate level measurement.
