Differential pressure/high static pressure transmitter, including 3151 metallic capacitive smart transmitter, 3151 micro differential pressure smart transmitter, 3151 metallic capacitive analog transmitter, etc. It is the pressure signal that is measured by taking low pressure side as reference, with only one port connected with process pipeline.
Work principle: when pressure acting directly or indirectly on the surface of measuring membrane, small deformation will occur on the membrane, high-precision circuit will transform the small deformation into voltage signal which is in direct proportion to the pressure, after compensation of temperature and pressure, then dedicated chip will transform the voltage signal into industrial standard 4-20mA current signal or 1-5V voltage signal. Measuring membrane has adopted with integrated circuit, inner containing linear compensation circuit and temperature compensation circuit, which ensures its high accuracy and high stability, and makes it suitable for using in all kinds of complicated industrial environment.
●Adoption of microprocessor enhances its flexibility and function;
● Have strong self-diagnostic capability;
● Without mutual effect between zero adjustment and range adjustment;
● Complete function of remote & local setting and calibration;
● Two-wire system, conforming to HART protocol and be capable of uninterrupted output with HART protocol terminal communication;
● Conduct compensation for temperature and static pressure by adopting digitized technology;
● Good stability, high accuracy, adjustable damping and good single-track overload ability;
● Without mechanical drive parts, little maintenance work, strong resistance to vibration;
● All general parts satisfy the convenience of maintenance;
● Membrane that contacts medium is optional for all-weather use.
