    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.

    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.
