6.1 Overview
The Model 3010MA Paramagnetic Oxygen Purity Analyzer is a
versatile instrument for accurately measuring percent oxygen
concentration in oxygen rich gas sample streams. Three user-definable
analysis ranges from 0-100% oxygen are available with auto-ranging and
range ID contacts. The analyzer employs a paramagnetic sensor and a
“split architecture” design to provide stable analysis across the
instrument’s analysis range. The Model 3010MA provides both voltage
(0-1VDC) and current (4-20 mA dc) outputs as a standard feature and
linear across the entire analysis range.
The Model 3010MA uses a “split architecture” design with the
Control Unit physically separate from the Analysis Unit to provide
additional stability for the paramagnetic sensor. These units are for indoor
use in a nonhazardous environment.
Part I of this manual covers the Control Unit while this part describes
the Analysis Unit. Installation of both units is covered in Part I Chapter 3.
The Analysis Unit contains:
 Paramagnetic Cell
 Oven and Temperature Sensor
 Sample System
The Control Unit contains:
 Operator Interface
 Main circuit board
 PID temperature controller
 Pressure compensation circuitry
 24VDC power supply for driving the Analysis Unit
 Digital meter readout and display circuit board
 Interface screen and circuit board
