Introduction

9/11 DirectLine® DL423 Sensor Module User Manual 1

1. Introduction

1.1 Overview

The DirectLine® Sensor consists of an electronics module connected to a

Conductivity Cell.

The electronics module is contained in a NEMA Type 4x sealed weatherproof,

corrosion/impact-resistant polysulfone housing that can be mounted at the end of an

immersion tube or in a sample line. The sealed plastic housing has plug-in

connections for the conductivity cells and 4-20 mA cordset.

1.2 Electronics Module

The electronics module is loop-powered by 16-42 Vdc and will modulate its supply

current from 4 mA to 20 mA, depending upon the conductivity value that is sensed

by the cell. The transmitted loop current is compensated for temperature internally

using the standard Honeywell 8550 thermistor.

For submersion or special wiring applications, the remote electronics module is

compatible with a remote cable/connector that allows the electronics module to be

Wall. Pipe, or DIN Rail mounted.

A 4-20 mA output connection is provided via a 6m cordset or a customer supplied

cable used in combination with a field wiring connector.

1.3 Operator Interface

The DirectLine® Sensor operator interface consists of three pushbuttons and one 4-

digit, 7-segment LCD display with 3 decimal points, plus (+), and minus (–) signs. It

is responsible for the display of measured values and configuration of parameter

values.
