ANALYTICAL INSTRUMENTS
Operator Interface
All controls and displays on the standard 3020T are available
from outside the housing. The instrument has two simple operator
controls. A digital meter, an alphanumeric display, and a sample
flowmeter give the operator constant feedback.

Standard Features
• An explosion proof NEMA 4/7 rated enclosure
• A 2-line alphanumeric display screen, driven by microprocessor
electronics continuously prompting and informing the operator
• High resolution, accurate readings of oxygen content from low t
ppm levels through 25%.
• Advanced Micro-fuel Cell designed for trace analysis, with a
one year warranty and an expected life of two years

MODEL 3020T
Process Trace
Oxygen Analyzer

T

eledyne’s Model 3020T Trace Oxygen Analyzer is
a microprocessor-based instrument for detecting
oxygen at the parts-per-million (ppm) level in a variety
of gases. This instrument serves as the explosionproof, bulkhead-mount version of the 3000 Series.
Simple menu choices, externally accessible command
switches, and dual LCD and LED displays make setup and operation clear and quick.

Analysis Ranges
Three user-configurable ranges are standard, with an
excellent linearity precluding the need to recalibrate
when changing ranges. Two fully programmable
concentration alarms satisfy nearly any requirement.
All features offer a sophistication that assures the
3020T will provide years of service.

Convenient Outputs For Data
Two standard 0-1 VDC outputs and two 4-20 mADC
isolated outputs provide both concentration and range
identification. A bi-directional RS-232 serial interface
is incorporated to relay information to a host computer
for remote monitoring of critical functions.

• Versatile analysis over a wide range of applications
• Microprocessor based electronics: 8-bit CMOS microprocessor t
with 32kB RAM and 128kB ROM
• Three user-definable output ranges (from 0-10ppm through 0250,000 ppm) assuring a perfect match for the user’s process.
• Air-calibration range for convenient spanning at 20.9%
• Auto-Ranging automatically selects 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 start-up and on demand
with continuous power-supply monitoring
• Two way RS-232 serial digital port for use with a computer or
other digital communication device
• Four analog outputs; two for measurement (0-1VDC and
Isolated 4-20mADC) and two for range identification

Applications
• Monitoring inert gas blanketing
• Air separation and liquefaction
• Chemical reaction monitoring
• Semiconductor manufacturing
• Petrochemical process control
• Quality assurance
