Fisher Torque Tube Displacer Level Transmitter
• Intelligent :275 or 375(with HART) communication, with query, configuration, marking, testing and other functions.
The instrument communication is superimposed on 4~20 mA the same two-wire circuit, and the data communication can be carried out simultaneously without interrupting the process signal.
High sensitivity: Hall element sensor can detect trace angle signal, the instrument is suitable for small specific gravity, interface measurement.
Good stability: because the sealed Hall element can provide no interference signal, the built-in filter in the controller can filter out the interference of output signal due to liquid level fluctuation.
Strong anti-interference: because the controller shell and junction box are equipped with anti-electromagnetic interference filter, the anti-interference ability of the instrument is increased.
The measuring room part can have visual function, and the liquid level condition in the buoy can be observed directly through the visual part of the measuring room, which is convenient for the user to install, debug and use.
