<1. INTRODUCTION AND GENERAL DESCRIPTION>
1.2 Application
The SC450G converter is intended to be used for continuous on-line measurement of
Conductivity,Resistivityand/orConcentrationinindustrialinstallations.Theunitcombines
simple operation and microprocessor-based performance with advanced self-diagnostics
and enhanced communications capability to meet the most advanced requirements. The
measurement can be used as part of an automated process control system. It can also be
used to indicate operating limits of a process, to monitor product quality, or to function as a
controllerforadosing/dilutionsystem.
Sensors should normally be mounted close to the converter in order to ensure easy
calibration and peak performance. If the unit must be mounted remotely from the sensors,
WF10extensioncablecanbeused,uptoamaximumof50metres(150feet),withaBA10
junction box, and up 10 metres standard sensor cable.
The SC450G is delivered with a general purpose default setting for programmable items
(seeChapter5).Whilethisinitialconfigurationallowseasystart-up,theconfiguration
should be adjusted to suit each particular application. An example of an adjustable item
is the type of temperature sensor used. The SC450G can be adjusted for a number of
different types of temperature sensors.
Details provided in this instruction manual are sufficient to operate the SC450G with all
Yokogawa sensor systems and a wide range of third-party commercially available probes.
For best results, read this manual in conjunction with the corresponding sensor instruction
manual.
Yokogawa designed the SC450G converter to withstand industrial environments. It meets
alltheCEregulatorystandards.Theunitmeetsorexceedsstringentrequirements(see
Chapter2)withoutcompromise,toassuretheuserofcontinuedaccurateperformancein
even the most demanding industrial installations.
