Part 1-Introduction
1.1General
The ModelQ46/85isanon-linemonitoring systemdesigned forthecontinuousmeasurement of
PeraceticAcid(PAA)concentrationinsolution.The fullscaleoperatingrangeof thesystemmay
be selectedbytheuserfor0-20.00 ppm,0-200.0 ppm,or0-2000 ppm,and the sensing system
willoperateon waterstreamswithtemperaturesranging from0to 50°C. The Q46/85PAA
Measurement Systemisengineered forapplicationsinwhichPAAisappliedto waterfor
sterilization purposes
The basicsensing element used inthe PAA monitoris apolarographicmembrane sensorwhich
measuresPAA directly.Watersimplyflowspastthesensorand directlyto drain,withthe flow
rate and pressureacross the sensorcontrolledbyaconstant head flowcell assembly.The PAA
measurement doesnot alterthe sampleoradd anychemicalsto thesamplestream,sothe water
flowcan return to the systemifdesired.
Q46/85Monitors areavailableintwobasicelectronicversions,a90-260 VACpowered monitor,
ora12-24 VDC powered monitor–bothwith three relaysand two 4-20 mAanalogoutputs.Both
versionsallowflexibleoutput optionswhichincludeadditional4-20 mAcurrent outputs,additional
0-30 VDC signalrelays,PID control, and digitalcommunication cards.

The standardmodelQ46/85 systemincludesthree maincomponents,theQ46 analyzer,a
constant head flowcell,and aPAA sensor.Alow-volumeflowcellisalsoavailablefor
applicationswheresampleflowrate and pressurecanbe carefullycontrolled. Figure1showsa
