Introduction
1.1 General
The Model 300P Percent Oxygen Transmitter is designed to accurately 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, 0–25% and 0–20.9% (air calibration range). The Model
300P is approved by Factory Mutual (FM) as intrinsically safe for operation in Class 1, Division 1, Groups A, B, C, and D hazardous environments.
The heart of the transmitter is Teledyne Brown Engineering's MicroFuel 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 4–20 mA dc current output that is directly and linearly proportional 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 configuration depends on the options selected at the time of purchase.
• Two analysis ranges: 0–25% and 0–20.9%
• 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.

Percent Oxygen Transmitter Operational Theory 2
Operational Theory
2.1 Transmitter Description
The transmitter consists of an RFI proof enclosure which contains the
O2 Sensor Assembly, 2-Wire Transmitter Circuitry and RFI Filters.
Mounted on the left side is a junction box which contains a three conductor
terminal strip for all external electrical connections. The bottom of the box
contains two bulkhead fittings for the 1/8" tubing used for bringing the
sample into and out of the sensor assembly. The transmitter assembly
contains four holes in the mounting flange for vertical surface mounting.
Access to the junction box is obtained by the removal of two screws
followed by the removal of the cover. Access to the O2 sensor and PC
board is through an RFI gasketed door held shut by 4 screw clamps.
2.2 Sensor Description
The Micro-Fuel Cell is a sealed plastic disposable oxygen transducer
that measures 1¼ inches in diameter and is ¾ inch thick (see Figure 2-1).
Inside of the cell are a cathode and anode immersed in 15% aqueous KOH
electrolyte. At one end of the sensor is a Teflon diffusion membrane; the
other end is sealed with a polyethylene membrane. At the rear of the cell is
a contact plate consisting of
two concentric foils. The

block assembly and provide
the electrical connection to
the rest of the analyzer.
The sensing cathode,

sion membrane, has a surface area of 2.48 cm2. The sample gas enters the
sensor block through an inlet tube between the cathode and the sensor
block cap, diffuses through the Teflon membrane, and any oxygen in the
sample gas is reduced on the surface of the cathode by the following
mechanism:
O2 + 2H2O + 4e
––
–
––
→ 4OH
––
–
––
(cathode)
When the oxygen is reduced at the cathode, lead is simultaneously
oxidized at the anode by the following mechanism.
––
–
2Pb → 2Pb+2 + 4e
––
(anode)
The electrons released at the surface of the anode flow to the cathode
surface via an external circuit. This current is proportional to the amount of
oxygen. It is measured and used to determine the oxygen concentration in
the gas mixture.
The overall reaction for the fuel cell is:
2Pb + O2 → 2PbO
The output of the fuel cell is limited by the amount of oxygen in the
cell at any one time, and the amount of stored anode material. In the
absence of oxygen, there is no current generated.
Warning: The sensor used in the Model 300P uses electrolytes which
contain substances that are extremely harmful if touched,
swallowed, or inhaled. Avoid contact with ANY fluid or powder
in or around the unit. What may appear to be plain water could
contain one of these toxic substances. In case of eye contact,
immediately flush eyes with water for at least 15 minutes. Call
physician. (See Appendix - Material Safety Data Sheet (MSDS)).
2.3 Circuit Description
The 300P circuitry consists of four stages: an input stage, a temperature compensation/ gain stage, a low-pass filter and an output voltage-tocurrent stage. The output of the O2 cell is a current directly proportional to
the amount of oxygen present. The input stage converts this current to a
voltage signal.
The temperature compensation stage consists of circuitry that amplifies the signal by a factor which is dependent upon the O2 cell temperature.
This temperature dependent gain is used to compensate for the rise in
output current of the O2 cell with temperature. A thermistor mounted in
the sensor assembly monitors this temperature and changes resistance (up
2-2
Teledyne Analytical Instruments
Percent Oxygen Transmitter Operational Theory 2
with lower temperature, down with higher temperature) so that the output
of this stage is constant over the temperature range at any given O
tration.
The output voltage-to-current stage (E to I) draws 4 mA from the
power supply loop when there is no oxygen present in the sample gas, and
20 mA when there is full scale oxygen present in the sample gas. It also
supplies the +5V and -5V required by the circuitry.
A 24V power supply is recommended to power the transmitter for
most applications. The actual minimum and maximum values of this
supply depend upon the total loop resistance, which consists of the input
resistance of the receiver and the resistance of the wires between the transmitter and the power supply. Power applied across the terminals of the
transmitter must be between 14V and 30V. Using this criteria, the maximum line resistance can be determined. For example, with a 24V power
supply, a maximum of 10V is available (24V-14V) for drop across the
input resistance of the receiver and the line resistance. This amounts to a
maximum loop resistance of approximately 500 ohms (10V divided by
0.02A).
concen-
2
The B-2 or B-2C cell used in this instrument normally generates
about 500 µA output current in air (20.9% O
). This is about 2 nA per
2
ppm.
2.4 RFI Protection
The Model 300P is designed to be RFI protected by virtue of the
electronics being mounted inside a grounded metallic enclosure. The RFI
protection, therefore, is maximized when the enclosure door is closed.

Percent Oxygen Transmitter Operation 3
Operation
Operation of the Model 300P Percent Oxygen Transmitter involves
installing the unit, making appropriate sample gas connections, and calibration.
3.1 Installation
WARNING: For FM approved intrinsically safe operation, an approved safety
barrier must be used to limit the line power to 26 VDC and 125
mA.
3.1.1 System Power Requirements
The Model 300P Percent Oxygen Transmitter requires a 24 VDC
(nominal), reverse polarity protected power source. The maximum and
minimum voltage is dependent on the safety barrier used.
3.1.2 Transmitter
The transmitter enclosure is a weather resistant bulkhead mounted
enclosure. Mount the enclosure to a vertical surface using the four mounting
holes in the flange. Mount the enclosure with the sensor pointing down in a
location where service personnel can reach it.
WARNING: If the enclosure is to be installed in a hazardous area, it must be
interconnected with approved intrinsic safety barriers.
Make gas line connections to the sample in and sample out 1/8 " tube
fittings at the bottom of the enclosure.
3.1.3 Junction Box
Power connections are made at the junction box located on the side of
the transmitter housing.
1. Remove the two screws securing the junction box cover and
remove the cover.

3 Operation Model 300P
3 Operation3 Operation
2. Connect the 2-wire shielded cable to the three terminal barrier
strip.
3. Replace the cover and screws.
3.2 Calibration
The calibration process consists of:
• Installing a milliammeter in series with the output signal as
described below
• Setting the electronic zero level
• Setting the span
Setting the zero and span of the transmitter requires adjustment of two
potentiometers (Pl and P2) located on the PC board inside the transmitter box.
NOTE: If the analyzer has more than one range, the selector switch should be
set to “B” (0-21%) during calibration and “A” during measurement
operations.
The Transmitter can be calibrated using either AIR or SPAN GAS.
Both methods are accomplished by adjusting two potentiometers (ZERO and
SPAN) located on the PC board inside the transmitter box.
Procedure:
1. Remove the junction box cover and remove the incoming wire
from terminal 2 of the barrier strip.
2. Connect a milliammeter in series between this wire and terminal

3.2.2 Setting the Electronic Zero Potentiometer (P2)5. Open
the transmitter box door and remove the Micro-Fuel Cell. Adjust P2 for a
meter reading of 4.00 +/- 0.01 mA.

6. Replace the Micro-Fuel Cell. Allow the reading to drop to a
stable low level (dependent upon the length of time that the
Micro-Fuel Cell was unshorted).

Percent Oxygen Transmitter Operation 3
3.2.2 Setting the Span Potentiometer (P1) using AIR
7. Set switch SW-1 to position “B” (AIR CAL) and flow air
through the system. This can be done by either disconnecting the
sample line and allowing air to flow or inserting a tee with
appropriate valves to allow switching between sample and air
without having to disconnect the sample in line.
8. After the reading was stabilized, set P1 to read a stable
20.00 +/- 0.01 mA output.
9. Return switch SW-1 to the operating position “A”.
3.2.3 Setting the Span Potentiometer (P1) using SPAN GAS
8. Set switch SW-1 to the normal operating position “A”. Flow a
span gas through the system and allow time for stabilization.
NOTE: The span gas should have an O2 concentration of 80% 100% of full scale. For example, if you have a 0-10%
transmitter, the span gas should be a certified grade gas of about
9% O2 in N2 or Argon.
9. Adjust span potentiometer P1 to read an output current
determined by the following equation:
Span Gas Concentration in %
+
mA = Output in mA
4
Full Scale Concentration in %
10. Remove meter and reconnect incoming wire to Terminal 2.
Replace junction box cover and close transmitter box door.
3.3 Operating the OxygenTransmetter
1. After calibrating the instrument, reconnect the sample in line if it
was disconnected.
2. Open the transmitter door and set switch SW-1 back to position
"A" if this has not already been done.
CAUTION: The 0–25% oxygen analysis range can be used to accurately
measure the oxygen concentration in a gas mixture containing up
to 24% Oxygen. Oxygen concentrations above 24% under extreme
conditions can cause the instrument to produce unreliable readings on the 0–25% oxygen scale. Use this range for gas mixtures
containing 0–24% oxygen only.

Percent Oxygen Transmitter Maintenance 4
Maintenance
4.1 Routine Maintenance
Aside from normal cleaning and checking for leaks at the gas connections, routine maintenance is limited to installing replacement Micro-Fuel
cells and recalibration. For recalibration, see section 3.2 Calibration.
4.2 Cell Replacement
The Micro-Fuel Cell is a sealed electrochemical transducer with no
electrolyte to change or electrodes to clean. When the cell reaches the end
of its useful life, it is replaced. The spent fuel cell should be discarded
according to local regulations.
The characteristics of the Micro-Fuel Cell are similar to those of a
mercury battery in that both provide an almost constant output throughout
their useful life, and then fall off sharply towards zero at the end. If the
process being analyzed has a low oxygen concentration, cell failure will
probably be indicated by the inability to properly span calibrate the transmitter, or excessively long response time to changes in oxygen concentration.
To avoid downtime, TBE/AI recommends that a spare cell be purchased shortly after the instrument is placed in service, and each time the
cell is replaced.
The spare cell should be carefully stored in an area that is not subject
to large variations in ambient temperature (75°F nominal), and in such a
way as to eliminate the possibility of incurring damage.
NOTE: Do not disturb the integrity of the cell package until the cell is to
actually be used. If the cell package is punctured and air is permitted to enter, the useful life of the cell will be adversely affected.

4 Maintenance4 Maintenance
To replace the cell:
1. Open the enclosure door.
2. The cell block is located in the center of the unit. Unscrew the
cap on the bottom of the cell block. The micro-fuel cell should
drop down once the cap is removed.
NOTE: Minimize the amount of time the cell is exposed to air. This will
lessen the time it will take the newly installed cell to drop to a zero
reading.
3. Remove the new cell from its package, and carefully remove
the shorting clip.
NOTE: Do not touch the silver colored sensing surface of the cell, as it is
covered with a delicate Teflon membrane that can be ruptured in
handling. Puncturing or other damage will require replacement of
the sensor
WARNING:The sensor used in the Model 300P uses electrolytes which
contain substances that are extremely harmful if touched,
swallowed, or inhaled. Avoid contact with ANY fluid or powder
in or around the unit. What may appear to be plain water could
contain one of these toxic substances. In case of eye contact,
immediately flush eyes with water for at least 15 minutes. Call
physician. (See Appendix - Material Safety Data Sheet (MSDS)).
4. Place the new cell on the cap with the sensing surface face
down and the gold contact rings up.
5. Position the cell and cap so that the cell is inside the cell block.
Press up on the cap and rotate until it threads. Tighten the cap.
4.3 Cell Warranty
The Class B-1 cell employed in the Model 300P is warranted for six
months of service. Other special cells may be used on occasion, depending
upon the application. Note any Addenda attached to the front of this
manual for special information applying to your instrument.
With regard to spare cells, warranty period begins on the date of
shipment. The customer should stock only one spare cell per instrument at
a time. Do not attempt to stockpile spare cells.
The B-1 cell should not be used in applications where CO2 is a major
component in the sample, however concentrations of 1,000 ppm or less
will not adversely effect the cell performance. Consult TBE/AI for optional
4-2
Teledyne Analytical Instruments
Percent Oxygen Transmitter Maintenance 4
cells which are available for either intermittent or continuous CO2 exposure.
If a cell was working satisfactorily, but ceases to function before the
warranty period expires, the customer will receive credit toward the purchase of a new cell.
If you have a warranty claim, you must return the cell in question to
the factory for evaluation. If it is determined that failure is due to faulty
workmanship or material, the cell will be replaced at no cost to the cus-
tomer.
NOTE: Evidence of damage due to tampering or mishandling will render
the cell warranty null and void.
