EB RF-Capacitance Level Transmitter

Principle

Capacitance Level Indicator: Utilizes the capacitance formed between the sensing probe and the metallic vessel wall. A high frequency sine-wave is applied between the probe and the vessel wall.
A change of the medium level will induce a change in the current of the applied sine wave.
From Z=1/2pfc, when the capacitance in the vessel increase, impedance will decrease and current will increase. Vice-versa, when the capacitance in the vessel is small, the impedance will increase and current will decrease accordingly.

Features
  • Suitable for high temperature, high pressure and corrosive environment.
  • Not affected by noisy, dusty, misty and changes in the temperature.
  • No blind distance, ideal for different tanks.
  • Economic for large tanks
  • 4~20mA output compatible for most control systems and meters
