Warranty
This equipment is sold subject to the mutual agreement that it is warranted by us free
from defects of material and of construction, and that our liability shall be limited to
replacing or repairing at our factory (without charge, except for transportation), or at
customer plant at our option, any material or construction in which defects become
apparent within one year from the date of shipment, except in cases where quotations or
acknowledgements provide for a shorter period. Components manufactured by others bear
the warranty of their manufacturer. This warranty does not cover defects caused by wear,
accident, misuse, neglect or repairs other than those performed by Teledyne or an autho-
rized service center. We assume no liability for direct or indirect damages of any kind and
the purchaser by the acceptance of the equipment will assume all liability for any damage
which may result from its use or misuse.
We reserve the right to employ any suitable material in the manufacture of our
apparatus, and to make any alterations in the dimensions, shape or weight of any parts, in
so far as such alterations do not adversely affect our warranty.
Important Notice
This instrument provides measurement readings to its user, and serves as a tool by
which valuable data can be gathered. The information provided by the instrument may
assist the user in eliminating potential hazards caused by his process; however, it is
essential that all personnel involved in the use of the instrument or its interface, with the
process being measured, be properly trained in the process itself, as well as all instrumenta-
tion related to it.
The safety of personnel is ultimately the responsibility of those who control process
conditions. While this instrument may be able to provide early warning of imminent danger,
it has no control over process conditions, and it can be misused. In particular, any alarm or
control systems installed must be tested and understood, both as to how they operate and
as to how they can be defeated. Any safeguards required such as locks, labels, or redun-
dancy, must be provided by the user or specifically requested of Teledyne at the time the
order is placed.
Therefore, the purchaser must be aware of the hazardous process conditions. The
purchaser is responsible for the training of personnel, for providing hazard warning
methods and instrumentation per the appropriate standards, and for ensuring that hazard
warning devices and instrumentation are maintained and operated properly.
Teledyne Analytical Instruments (TAI), the manufacturer of this instrument,
cannot accept responsibility for conditions beyond its knowledge and control. No state-
ment expressed or implied by this document or any information disseminated by the
manufacturer or its agents, is to be construed as a warranty of adequate safety control
under the users process conditions. iii

Introduction 1
Introduction
1.1
General
The Model 300P Percent Oxygen Transmitter is designed to accu-
rately monitor the oxygen content on a percent basis in a wide variety of
gases. The Percent Oxygen Transmitter is equipped with two oxygen
analysis ranges, 025% and 020.9% (air calibration range). The Model
300P is approved by Factory Mutual (FM) as intrinsically safe for opera-
tion in Class 1, Division 1, Groups A, B, C, and D hazardous environ-
ments.
The heart of the transmitter is Teledyne Brown Engineering's Micro-
Fuel Cell oxygen sensor. This cell is a sealed electrochemical device which
translates the amount of oxygen present in a sample into an electrical
current. Since it is sealed, there is no electrolyte to change or electrodes to
clean and therefore, virtually maintenance free.
The transmitter operates from a 24 VDC (nominal) power source and
produces a 420 mA dc current output that is directly and linearly propor-
tional to the oxygen concentration. The output current is used to interface
with devices such as recorders, alarms, computers or other current driven
devices.
1.2
Features
The following features describe the basic model. The exact configura-
tion depends on the options selected at the time of purchase. Two analysis ranges: 025% and 020.9% High sensitivity (0.5%) Accurate (�2% of full scale at constant temperature and
pressure of calibration) or �5% of full scale over the operating
temperature range. Teledyne Analytical Instruments
