Product Description
Transmitter HART Protocol Smart Differential Pressure Pressure Gauge 4-20ma Digital Differential Pressure Transmitters Price
NCS Series of Intelligent Transmitter have been designed with high precision and high reliability, high stability. The pressure, temperature, currents and other physical quantities are displayed on LCD module. Zero drift, range settings and many other functions, are realized by the magnetism bar operation. The interoperability between different systems and equipments are realized by the Equipment Description Document, which is coMpatible to a variety of device management software, and adapting to harsh electromagnetic environment. NCS Series of Intelligent Transmitter have been used in inflammable and explosive places according to Intrinsically Safety Design.

Working Principle
Introduction for Working Principle
The widely used 3151 capacitive pressure sensors, which were developed by Rosemount initially in USA, have been produced on a large scale in China. The core of its sensor is differential capacitive membrane, as picture shows. There are two measurement capacitances CH and CL distributed in differential capacitive membrane. The two measurement capacitances are almost equal to two plate capacitances because of their mechanical structure. The two measurement capacitances share one polar plate, which is a measure membrane in the center. And the other polar plate is fixed on the two sides. When the pressures of two sides are equal, the measure membrane is in the center, the capacitances of two sides are equal too. But when the pressure of high pressure side is higher than that of low pressure side, the guide pressure liquid filled in the membrane guides the differential pressure, so that the measure membrane moves to low pressure side. As a result, the capacitance of high pressure side is lower than that of the low pressure side.

Wiring
The power and signal of Smart Transmitter are sharing one pair of cables (Bus Cable). The ordinary cables can be selected by HART smart transmitter, but FF, PA Smart Transmitter is suggested to use specific Fieldbus cable the IEC61158-2 recommended. The terminal is at the rear cover, the terminal wiring board could be seen after screwing the rear cover (indicated “FIELD TERMINAL”).
