Page 7: Introduction
Introduction 1. Introduction 1.1 Overview The DirectLine® Sensor for dissolved oxygen measurement in water consists of a DL424/425 electronics module connected to a DL5000 DO Probe. The modular electronics design allows the module to be separated from the probe, so that the probe can be easily removed or replaced while retaining power to the electronics module. -
Page 8: Electronics Module
Introduction 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 DO value that is measured by the probe. The transmitted loop current is compensated for process temperature. 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. -

Page 13: Integral Mounting
Installation 2.2 Integral Mounting Table 2-2 Integral Mounting Procedure (refer to Figure 2-3) Step Procedure Connect the probe to the process source (using the appropriate mounting from those supplied for the DL5000). Make sure that the final position of the installed electronics module allows the display to be easily viewed by personnel. -
Page 14: Remote Mounting
Installation 2.3 Remote Mounting When the DL424 or DL425 module is specified with Table II = 6, a remote connector assembly (part number 51500768-005) is supplied loose. The remote cable connector is used to connect the DL5000 probe cable to the DL424/425 module. Table 2-3 gives the mounting procedure. -

Configuration 3. Configuration 3.1 Overview Configuration Parameters Set Up consists of configuring the following functions: Atmospheric Pressure Compensation: Table 3-1 Dependence of Barometric Pressure on Altitude The solubility of oxygen in water and DL5000 dissolved oxygen probe signal directly respond to barometric pressure and hence pressure compensation is Alt, ft P, mmHg... - Page 20 Configuration Probe Bias Voltage – The probe bias voltage value determines the voltage applied to the DO probe's cathode, relative to the reference electrode, to drive the reduction of oxygen to water at the cathode and thereby induce a current which is directly proportional to the oxygen consumed.
