UTZ series displacer level transmitter
Overview
UTZ series intelligent torsion tube buoy liquid level transmitter is our company's own research and development of field data processing liquid level control instrument. Buoyancy drives the torsion tube and the core shaft to produce the angle change, at the same time also changes the sensor signal in the transmitter, this signal passes through the advanced signal processor, outputs the standard current signal 4-20 mADC, uses the backlight liquid crystal display, he processor has the functions of linearization, measurement error, automatic temperature compensation, HART communication and so on. The displacer level transmitter can be used to control and measure the liquid level, boundary or density of the medium. This series of products is widely used in petroleum, chemical, electric power, metallurgy, food, paper, environmental protection and other industries.

UTZ series intelligent displacer level transmitter
Overview
UTZ series intelligent buoy liquid level transmitter is a product produced by Dandong Dedan Trade Co., Ltd and Fisher Control equipment Company. A part of the transmitter is introduced into the DLC3000 transmitter produced by Fisher Control equipment Co., Ltd., and the buoy liquid level sensor (inner cylinder assembly) and the measuring room part are manufactured by our company. The product is widely used in liquid level control and measurement in petroleum refining, chemical, thermal power plant, metallurgy, pharmaceutical, light industry and other industries.
Characteristics
• 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. This product is the company patent product, patent number :200520091104
