Single flange pressure transmitter
Products overview:
ZW0351LT seriesSingle flange pressure transmitterThe use of advanced microprocessor technology and digital communication technology.Except with normal intelligence fully functional, but also has a series of enhanced capabilities, such as automatic zero adjustment, remote local control parameter check and adjust the control parameter password lock, etc.HART protocol, at the same time through the fieldbus remote parameter setting, remote control, since the diagnosis, and other functions.Fieldbus is a two-way digital communication system, the innovation of technology is to configure the instrument control system, is also a good prospect of updated products, used to replace now field instruments widely used in the standard 4-20 ma analog communication.
Second, the working principle:
ZW0351LT single flange series pressure transmitter is by measuring the principle of the diaphragm and on both sides of the insulation slices on the electrodes of a capacitor.When inconsistent pressure on both sides, to cause measuring diaphragm displacement, the displacement and stress is directly proportional to the difference, so both sides capacitance range, through the link of oscillation and demodulation, is converted into is proportional to the pressure signal, after temperature compensation and the linear correction, converted into a standard electrical signals.
Applications:
ZW0351LT series, the main structure of the single flange pressure transmitter and pressure transmitter is the same, in order to adapt to different installation requirements, this series transmitter has many forms of remote transmission device for the user to choose from.The products are widely used in petroleum, chemical, electric power, food, paper making, municipal engineering and other industries.
1, high temperature viscous medium;
2, easy to be crystallized media;
3, with solid particles or suspended solids precipitation medium;
4, strong corrosive or toxic medium;
Can eliminate guide the occurrence of pressure pipe leakage pollution environment;Using spacer can be avoided, because of the measuring signal is not stable, needs to add spacer often tedious work.
Accurate measurement in 5, interface and density;
Far eastone device can avoid different instant media fusion, so that the measured results truly reflect the actual situation of process changes.
6, requiring high health clean;
Such as food, beverage and pharmaceutical industry production, not only requires the transmitter medium contact conform to the hygiene standards, and should be easy to wash, to prevent cross contamination of different mass media.
Four, the main features:
1, indicating novel, intuitive reading and eye-catching, observing the direction of the indicator can be based on user need to change the point of view.
There were 2, simple structure, moving or elastic element, so stay on sex is extremely high, little maintenance.
3, installation is convenient, built in especially shows the characteristics of the structure, without any special tools.
4, easy to adjust, zero and span two potentiometer can be zero within the scope of the liquid level detection effectively any migration or range change, two adjustment each other.
5, wide range of USES;Suitable for high temperature and high pressure, strong corrosive medium level measurement.
6, large measuring range, not restricted by storage tank height.
7, indicating device, and is completely isolated measured medium, good sealing, high reliability, the use of safe.
8, have the ability to safety explosion protection and isolation and can be applied to all kinds of dangerous sites.
9, with anti blocking design can be realized to paste medium level measurement.
10, fine unique zero, full range, nonlinear compensation, guarantee conditions of use within the scope of the precision, good stability for a long time.
