10.RF-Capacitance Level Transmitter-EB Series

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

14. FMCW Radar Level Transmitter-JFR Series

Principle

FMCW
radar adopts a high frequency signal, which is emitted via an antenna

reflected by the target surface and received at a time delay. The
frequency difference, which is calculated from the transmitting
frequency and the received frequency, which is directly proportional to
the measured distance (or material surface).

15. Rotary Paddle Level Switch-SE Series

Principle

The
SE series operating principle is simple. A unit is usually located
through a bin wall at the top, middle or low level of a bin. During
normal operation (no material present) a synchronous motor rotates the
paddle at 1 RPM. When this paddle rotation is impeded by material,
surrounding the paddle, motor will stall and cause the Micro-switch to change state. (indicating an alarm or control)
