ANALYTICAL INSTRUMENTS
for years with little or no attention making them ideal for critical
measurements in the low percent range.

300 0 MA

FLEXIBILITY
The 3000MA offers three dynamic, user configurable ranges
plus autoranging, and can be calibrated in any range. The
instrument is linear on all three ranges, eliminating the need
to recalibrate while switching between ranges. The analyzer
comes standard with an isolated 4-20 mADC output for oxygen
concentration and range identification. Additionally, a bidirectional RS-232C serial communication interface provides
for remote monitoring and control of span and zero functions.
Teledyne provides auto-calibration capabilities as a standard
feature in the 3000 series platform.
APPLICATIONS
• Monitoring inert gas blanketing

Paramagnetic Oxygen Analyzer

• Microprocessor based
• Exceptional performance, price value
• Advanced paramagnetic sensor
• Designed for air separation industry
Teledyne’s Model 3000MA Paramagnetic Percent Oxygen Analyzer is a
versatile, microprocessor based instrument specifically designed to detect
oxygen in a variety of gases. The 3000MA is a precise, cost effective
instrument capable of measuring percent oxygen in as low as the 0-1%
range. Drawing on the solid performance of Teledyne’s highly successful
3000 series control platform, the 3000MA provides the user with a wide
variety of features and options to satisfy virtually any application.
PRINCIPLE OF MEASUREMENT
The physical property distinguishing oxygen from other gases is its
paramagnetism which is significantly greater than that of common gases.
Consequently the molecules of oxygen are attracted by strong magnetic
fields which can be used in detection.
A paramagnetic sensor consists of two spheres arranged in the form of a
dumbbell suspended in a symmetrical, non-uniform magnetic field. When
the surrounding gas contains oxygen, the dumbbell spheres rotate out of the
magnetic field by the relatively strong attraction of oxygen.

• Air separation and liquefaction
• Chemical reaction monitoring
• Emissions monitoring
• Petrochemical process control
• Quality assurance
• Gas analysis certification
THE LEADER IN OXYGEN
The 3000MA can be ordered as a standard unit or as part of
a larger analytical system. With over 50 years of analytical
instrument experience, Teledyne supplies sensors, custom
engineered analyzers and complete monitoring systems to
satisfy unique applications. From portables to on-line units,
in microprocessor based or analog configurations, no other
manufacturer comes close to matching Teledyne’s breadth of
instrumentation.
ADVANTAGES
• Linearity of analysis across three user-selectable t
ranges
• Autoranging to follow process upsets
• Auto-calibration electronics standard

A light beam focused on a mirror attached to the dumbbell reflects
asymmetrically onto two photo diodes resulting in a voltage shift. The voltage
difference produces a current used to drive the dumbbells back to the original
position. The current flow required to maintain the null position is directly
proportional to the oxygen concentration and is shown linearly in volume
percent oxygen in the display. Properly maintained paramagnetic sensors last
