Fine Tek 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

11.Magnetic Float Level Transmitter-FG Series

Principle

“Magnet Float Level Indicator” is composed of the float and sensing rod (shown as below). As the float raised or lowered by liquid level, the sensing rod will have a resistance output, which is directly proportional to the liquid level. Also, the float level indicator can be equipped with the TAB-1531 (please see page 3) to produce a 0/4~20mA signal. In addition, we can use with PB series bargraphic display scaling panel meter for level control and display. Anyway, “Magnet Float Level Indicator” is a great benefit to all kinds of industries with its easy working principle and reliability.

Features

  • Every sensing element is protected by a plastic package, safety in use and transport.

  • High performance and reliability of electric circuit modular designed.

  • Lower installation costs, less maintenance, reduced personnel training, and decreased plant shock down time.
