1 Introduction
•
Advanced Paramagnetic sensor, designed for percent oxygen
analysis. Several options are available.
•
Versatile analysis over a wide range of applications.
•
Microprocessor based electronics: 8-bit CMOS microprocessor
with 32 kB RAM and 128 kB ROM.
•
Three user definable output ranges (from 0-1% through 0-100 %)
allow best match to users process and equipment.
•
Air-calibration range for convenient spanning at 20.9 %.
•
Auto Ranging allows analyzer to automatically select the proper
preset range for a given measurement. Manual override allows
the user to lock onto a specific range of interest.
•
Two adjustable concentration alarms and a system failure alarm.
•
Extensive self-diagnostic testing, at startup and on demand, with
continuous power-supply monitoring.
•
Two way RFI protection.
•
RS-232 serial digital port for use with a computer or other digital
communication device.
•
Analog outputs for percent-of-range and for range identification.
0–1 V dc. (Isolated 4–20 mA dc optional)
•
Convenient and versatile, steel, flush-panel or rack-mountable
case with slide-out electronics drawer.

Model Designations
3000MA:
Standard model.
3000MA-C: In addition to all standard features, this model also has
separate ports for zero and span gases, and built-in control
valves. The internal valves are entirely under the control of
the 3000MA electronics, to automatically switch between
gases in synchronization with the analyzer's operations.
3000MA-M: This model has current output signals (4-20 mA) for percent-
of-range and range ID, in addition to voltage outputs.
