0.1~16s Adjustable 24VDC IP67 NY3051 Pressure Sensor Transmitter
NP3051 series intelligent differential pressure/pressure transmitter is an intelligent field instrument conforming to HART protocol. Using the original imported diaphragm in the design of the micro external processor and HART communication circuit, you can store any support HART communication protocol of the upper computer software or HART communication protocol in line with the 268, 275 and other hand-operated device for two-way communication, and with a 5-digit intelligent digital LCD display, you can display the differential pressure / pressure value, the output current value and output percentage value, debugging is very convenient, to achieve the Transmitter digital and intelligent functions, and compatible with the traditional 4 ~ 20mA analog output signal, so as not to change the control system to achieve and analog meter interchangeable.
NY3051 Pressure Sensor Transmitter Working Principle
NP3051 series intelligent differential pressure / pressure transmitter has a variable capacitance sensing assembly called "δ" chamber see the figure below, the process pressure is transmitted through the "δ" chamber on both sides of the isolation diaphragm, filling fluid to the "δ " chamber to the center diaphragm. The center diaphragm is a tension elastic element, which produces a 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 pole plate. The differential capacitance is converted into a standard output signal by an electronic circuit.
NY3051 Pressure Sensor Transmitter Design Feature
1. High precision and good stability.
2. With continuous self-diagnosis, linear compensation and digital fine-tuning function.
3. Local adjustment of zero position and range can be realized, and remote adjustment can also be realized by remote hand controller or computer.
4. Linear or square root output can be selected according to different applications.
5. Damping time can be set to change between 0.1~16s.
6. Pressure value unit conversion between KPa, Pa, InH20 bar, etc. can be realized.
7. Failure and safety modes can be set by toggling the failure/safety switch.
8. With single point, multi-point and burst mode.
9. With power failure protection function, it can save its working data automatically when power failure.
10. Solid components, plug-in printed circuit board Small, light weight, strong and shock-resistant.
11. Good one-way overload protection characteristics.
