NP-3051 Pressure Sensor Transmitter
NP3051 series intelligent differential pressure / pressure
transmitter is an intelligent field instrument in accordance with
HART protocol. The original imported diaphragm is designed with a
microprocessor and a HART communication circuit. It can communicate
bidirectional with any host computer software supporting HART
communication protocol or 268,275 hand-operated devices that
conform to HART communication protocoL With 5 bits intelligent
digital liquid crystal display, the differential pressure /
pressure value, output current value and output percentage value
can be displayed on the spot. The debugging is very convenient, and
the digital and intelligent functions of the transmitter are
realized. And with the traditional 4〜20mA simulation input The
output signal is compatible so that the exchange with the analog
table can be achieved without changing the control system.

NP-3051 Pressure Sensor Transmitter Operating Principle
NP3051 series of intelligent differential pressure / pressure
transmitters have a sensor assembly with variable capacitance,
called ”6” chamber. The process pressure.
NP-3051 Pressure Sensor Transmitter Design Features
◎ High precision, good stability;
◎ It has the function of continuous self-diagnosis, linear
compensation and digital fine-tuning.
◎ It can adjust the zero bit on the spot, measure range, and
realize remote adjustment by the remote hand manipulator and
computer.
◎ Linear or square root output can be selected according to
different applications.
◎ The damping time can be set between 0.1 and 16s.
◎ The conversion of pressure units between KPa?Pa,InH2O,bar and others can be realized.
◎ The failure and safety mode can be set by turning the failure /
safety switch.
◎ With single point, multi-point and burst mode;
◎ The utility model has the function of power off protection and
can automatically save its working data when the power is off.
◎ Solid components, connection-type printed circuit board small,
light weight, strong seismic;
◎ Good one-way overload protectio.
