329R Introduction 1.0
Introduction
The Teledyne Analytical Instruments Model 329R Oxygen Detector
measures the percent of oxygen in a wide range of gases and gas mixtures.
Modular and compact design provide outstanding performance and reliable
on-line monitoring and make the 329R virtually maintenance-free.
A special range on the 329R enables you to calibrate in ambient air.
The Micro-Fuel Cell produces an output that corresponds linearly to the
oxygen concentration; the absence of oxygen produces zero current. This
means you can use ambient air (20.9% oxygen) to calibrate, eliminating
the need for special span gases.
The Model 329R contains a main PC board and power supply/inter-
connection board housed in a rack mount enclosure. The oxygen probe can
be separated from the unit by as much as 6 feet, depending on the level of
electromagnetic noise in the operating environment.
Main Features
1. Two Ranges of Analysis. The Model 329R Oxygen Monitor
features two analysis ranges: 0-3% and 0-10%. A 0-25% range is acces-
sible only during calibration to allow calibration in air. Optional 0-1%, 0-
25%, and 0-100% ranges are available.
2. Liquid Crystal Display Digital Readout. The digital front panel
LCD continuously displays and updates O

monitoring levels and displays
values when calibrating the instrument and setting the alarms.
3. Percent of Range Alarms. Three (3) alarm relays are provided:
one high and one low alarm, which are user adjustable, and one low alarm,
factory set as a cell fail alarm at 2% of full scale.
4. Proven Sensor. The 329R uses the Class E-2 Micro-Fuel Cell,
warranted for 24 months, with a life expectancy of 48 months.
