Good Stability Differential Pressure Transmitter One-Way Overload Protection
Working Principle of Differential Pressure Transmitter
NY3051 series intelligent differential pressure/pressure transmitters have a sensing component with variable capacitance, called the "σ" chamber (see figure below). The process pressure is transmitted to the central diaphragm of the "σ" chamber through the isolation diaphragm on both sides of the "σ" chamber and the filling fluid. The central diaphragm is a tensioned elastic element, which produces a deformation displacement corresponding to the pressure difference between the two sides acting on it, and this displacement is transformed into a differential capacitance formed on the capacitive plate. Conversion of differential capacitance into standard output signal by electronic circuit.
Design feature of Differential Pressure Transmitter
◎High accuracy and good stability
◎With continuous self - diagnosis, linear compensation and digital fine - tuning functions
◎You can adjust the zero and range locally, or remotely by using a remote manual operator or computer.
◎You choose linear or root output, depending on the application.
◎Damping time can be set between 0.1~16s;
◎It can realize the conversion of pressure value units between KPa, Pa, Inh2o, Bar, etc
◎You set failure and safety modes by toggling a failure/safety switch.
◎It has single point, multi-point and burst modes
◎it has power-off protection function, and can automatically save its working data when power is off;
◎solid components, plug-in printed circuit boards, small, light, strong and earthquake resistant;
◎good one-way overload protection
