Micro differential pressure sensor NT51C series

Product Overview

The NT51C series diffusion silicon differential pressure transmitter consists of a differential pressure sensor and an integrated amplifier circuit, which has the advantages of high stability and good dynamic measurement performance; Configuring high-performance microprocessors to correct and compensate for sensor nonlinearity and temperature drift, achieving precise digital data transmission, on-site device diagnosis, remote bidirectional communication, and other functions, suitable for use in measurement and control of liquids and gases.

This transmitter has multiple range options to meet the needs of various users. It is widely used in various fields such as metallurgy, machinery, petroleum, chemical industry, power station, light industry, food, environmental protection, national defense, and scientific research.

Product working principle

The working principle of the diffusion silicon differential pressure transmitter is that the process pressure acts on the sensor, which outputs a voltage signal proportional to the pressure. The voltage signal is converted into a 4-20mA standard signal through an amplification circuit. The power protection circuit provides excitation for the sensor, which adopts a precision temperature compensation circuit.
