Introduction

Principle & Structure

KAP40 pressure transmitter is an intelligent measurement and control product that integrates pressure measurement, display, and transmission output. It corrects and compensates for sensor nonlinearity and temperature drift, and adjusts transmitter parameters online through a handheld communicator to achieve accurate digital/ Data transmission, field device diagnosis, remote two-way communication.

Features

● Wide measurement range and full structure;

● With HART communication protocol or RS485 communication protocol;

● High-brightness LCD pressure field display & LED optional.

application

Non-corrosive gas and liquid pressure measurement of 316L stainless steel;

Used in petroleum, chemical, metallurgy, electric power, hydrology and other industrial process sites.
