High Stability 3051 Differential Pressure Transmitter For Gas Liquid Vapor Pressure Measurement Applications

Autodiagnosis 3051 Differential Pressure Transmitter High Pressure Stable Working Principle

NY3051 series intelligent differential pressure/pressure transmitter is an intelligent field type instrument according to HART protocol. With original imported diaphragm design, The microprocessor and HART communication circuit can be used for two-way communication with any upper computer software that supports the HART communication protocol or 475 as well as other manual operators that conform to the HART communication protocol. It is also equipped with a 5-bit intelligent digital LCD display, which can show the differential pressure/pressure value, input value and output value on site. Debugging is very convenient, to realized digital and intelligent functions of the transmitter. It is compatible with the traditional 4~20mA analog output signal, so it can be interchanged with the analog meter without changing the control system.

NY3051 series intelligent differential pressure/pressure transmitter has a variable capacitance sensing component called“ δ” Chamber, the process pressure is transmitted to the“ δ” The central diaphragm of the chamber. The central diaphragm is a tensioned elastic element, which generates corresponding deformation displacement for the pressure difference between the two sides acting on it, and this displacement is transformed into the differential capacitance formed on the capacitor plate. The differential capacitance is converted into standard output signal by electronic circuit.

3051 Differential Pressure Transmitter Design Feature

◎ High precision and good stability;

◎ With continuous self diagnosis, linear compensation and digital fine adjustment functions;

◎ Local adjustment of zero position and range can be realized, and remote adjustment can also be realized through remote manual operator and computer;. Linear or square root output can be selected according to different applications; The damping time can be set to change between 0.1~16s;

◎ The unit of pressure value can be converted between KPa, Pa, Inlz0, bar, etc; Failure and safety modes can be set by toggling the failure/safety switch; With single point, multi-point and intermittent modes:

◎ With power failure protection function, the working data can be saved automatically when power failure occurs;

◎ Solid components, plug-in printed circuit board is small, light, strong and shock resistant;

◎ Good at unidirectional overload protection:
