Introduction

Principle & Structure

KAP33 digital pressure transmitter controller is an intelligent measurement and control product integrating pressure measurement, display, contact control and transmission output. It has RS485 communication interface, and can realize network, digital signal transmission and transmitter through RS485 bus function. Parameter remote setting and adjustment. It can also be directly installed at the on-site pressure measurement point. You can use the buttons to set various parameters such as zero point, full scale value, contact pressure, control pressure, etc., to accurately measure and control the on-site pressure, differential pressure, and liquid level, and send other The equipment provides standard analog signals or intelligent multi-functional products that provide contact control signals.

Features

Wide measurement range, all stainless steel structure.

High-brightness LED pressure on-site display.

RS485 communication interface.

Up to four control contacts can be provided.

The contact value and contact state can be set arbitrarily, and the control is accurate and reliable.

application

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

Used in petroleum, chemical, metallurgy, electric power, hydrology and other industries.
