High Precision Differential Pressure Transmitter Power-Off Protection Function

Working Principle of Differential Pressure Transmitter

NY3051 series intelligent differential pressure / pressure transmitter has a variable capacitance sensing component called“ σ” Chamber (see the figure below), process pressure through“ σ” Isolation diaphragms on both sides of the chamber and filling liquid are transmitted to“ σ”, the central diaphragm of the chamber. The central diaphragm is a tensioned elastic element, which produces corresponding deformation displacement for the pressure difference on both sides acting on it, and this displacement is transformed into a differential capacitance formed on the capacitor plate. The differential capacitance is converted into a standard output signal by an electronic circuit.

Design feature of Differential Pressure Transmitter

◎High accuracy and good stability

◎with continuous self diagnosis, linear compensation and digital fine-tuning 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 and 16S;

◎The pressure value unit can be converted between kPa, PA, inh2o, bar, etc

◎The failure and safety modes can be set by toggling the 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
