Introduction

Principle & Structure

PE-TF differential pressure transmitter is used to measure the pressure of liquid, gas and steam. After the PET differential pressure/pressure transmitter is equipped with a remote sealing device, it becomes a PETF remote differential pressure transmitter, which still has various characteristics of the PET differential pressure/pressure transmitter.

main feature

● Zero point and range can be adjusted on site

● 4-20mA output with HART communication protocol

● High precision and good stability.

● High static pressure, resistance to overpressure

● Good repeatability, with temperature compensation.

● Can be used for corrosive, high temperature type, easy to crystallize and clogging medium measurement

● Standard configuration HART communication protocol

● With explosion-proof function

● Damping can be adjusted

application

Suitable for a variety of harsh working conditions.

Mainly used for industrial process control, by choosing different diaphragms, it can be applied to a variety of working conditions, such as corrosive, high temperature type, easy to crystallize, easy to block, high viscosity medium measurement.

Suitable for measuring water, oil and gas media.

Used in steel mills, power plants, aviation, coal, mud, pulp, paper, food machinery and other industries.
