Differential 4..20ma Pressure Level Sensor Transmitter

Differential 4..20ma pressure level sensor transmitter

Product Description:

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.

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
