Product Description

Smart Differential Pressure Transmitter with Integral Flange

 

Overview

With advanced microprocessor technology and state-of-art silicon pressure sensor, the 3051 series intelligent differential pressure transmitter provide an accurate, reliable and economic solution for wire range of pressure measurement application. To reach the best performance, every silicon pressure sensor in our transmitter is specially temperature compensated, non-linear compensated, tested and screened before assembly.

 

Application

Measurement of fluid flow (gas, vapor, liquid)

Measurement of liquid level, volume and mass

Differential pressure control

 

Feature

Real time configuration during operation

The pressure signal can be intelligently linearized

Reverse connection protection on circuit board, current limitation.

The configured parameter keeps same after stored in E PORM

High precision and high stability

Rough structure and anti-vibration components and plug-in PCB

Explosive proof configuration

Sensor trim, zero trim and damp can be continuously adjustable
