1.1 OVERVIEW
The Model 7003M Percent Oxygen Analyzer continuously monitors the concentration
of oxygen in a gaseous sample. It consists of a sensor and the analyzer. The sensor
is housed in a chamber assembly and is connected to the analyzer by a shielded
multi-conductor cable.
The Model 7003M Percent Oxygen Analyzer provides direct digital readout, isolated
current output, automatic temperature compensation circuitry, and dual relay contact
closures for alarms or ON/OFF control devices as standard features. The alarm
ranges can be selected independently from the output range, eliminating the need to
readjust alarm setpoints if the range is changed.
The analyzer has six modes of operation:
MODE FUNCTION
RUN (see Section 3.4) Normal monitoring
SETUP (see Section 3.5) Changing parameters
ALARM/CONTROL (see Section 3.6) Set alarms or ON/OFF controllers
CALIBRATION (see Section 4.2) Gas calibration/pressure inputs
HOLD (see Section 4.3) Retain last output value
DIAGNOSTICS (see Section 4.4) Electronics checks
The Model 7003M Percent Oxygen Analyzer is housed in a NEMA 4X (CSA enclosure
4), corrosion resistant housing suitable for panel, pipe or wall mounting.
The analyzer has a microprocessor controlled keyboard for operation. Signals from
the remote oxygen and temperature sensors are processed to compute real time
oxygen concentration corrected for temperature, constant pressure differences and
residual sensor current. The oxygen concentration is compared with user-set alarm
parameters, and also generates an isolated 4 to 20 or 0 to 20mA signal. Data is
stored in a memory circuit that retains the data in case power is removed.
The analyzer is shipped from the factory configured for operation on either 115 VAC
or 230 VAC, 50/60 Hz as specified by the customer when ordered.

NTRODUCTION

1.2 PRINCIPLE OF MEASUREMENT
Measurement is based on the electro-chemical reaction between oxygen and the
sensor cathode which produces a low level electrical current. The sensor signal is
proportional to the partial pressure of oxygen present at the membrane. This signal
and a thermistor signal are received by the analyzer and processed by the electronics
to output a calibrated oxygen signal that is compensated for temperature.
1.3 SENSORS
Rosemount Analytical offers rechargeable and disposable oxygen sensors which can
be used with the Model 7003M. These sensors are supplied in kits: Submersion, inline flow, fast response, and a cell separation kit. Sensors are available constructed
of polypropylene or Ryton. See Section 7.3 Replacement Parts - Sensors, for
additional information.
1.4 CONDITIONS AFFECTING MEASUREMENT
Oxygen measurement is affected by the following:
• Composition of the sampled gas
• Sample and calibration gas pressures
• Environment of sensor, cable and analyzer
Each must be considered when calibrating and operating the analyzer to obtain
accurate measurements.
1.4.1 G
AS COMPOSITION
Any substance in the sample that significantly interferes or "poisons" the sensor
oxygen reading should be removed by a chemical and/or mechanical sample handling
system (see Section 5.2). If ambient air is not used as the span gas, the composition
of calibration gases should also be representative of the sample.
The sample and calibration gases must meet certain specifications (see Specifications
in Preface) to ensure accurate measurement. Physical parameters that affect
measurement include:
• Pressure
• Humidity
• Temperature
• Gas composition
Also refer to Section 5.2 for additional information about how gas conditions affect the
oxygen measurement.

NTRODUCTION
I
1.4.2 S
AMPLE AND CAL GAS PRESSURES
The sample and calibration gases may be at different pressures as long as the
pressure of each remains constant. Any variation in the pressure of either gas will
result in an incorrect output reading of the same proportion.
Two methods of sample calibration are recommended:
1. Calibrate at the sample pressure, or
2. Calibrated at a different pressure, and enter the two pressure in the analyzer
(Section 4.2.3)
Refer to Section 5.2 for a more detailed discussion of the relationship between gas
pressures and apparent oxygen concentration.
1.4.3 E
NVIRONMENTAL FACTORS
If radio frequency interference (RFI) normally occurs in the operating environment, the
sensor cable should be electrically shielded during installation.
1.5 FEATURES
UPPRESSED RANGES
S
When setting the Model 7003M to a suppressed output range (15 to 25%, etc.), note
that the absolute accuracy, drift, and noise of the oxygen measurement will remain the
same for all ranges (see Specifications in Preface).
ALAR M M
ODE
ALARM Mode is not self-resetting. Operator must press ACK to bring relays back to
their no-alarm state. Used when immediate operator action is required.
Note:
Operator Can Bypass Alarm Relays
When relays are set to ALARM Mode (Section 3.6.1) and an alarm condition has
occurred, pressing the ACK key will turn off the relay switch, whether the
oxygen level is out of range or not. If you do not want an operator to be able to
bypass the relay switches in this way, set the instrument to ON/OFF -CONTROL
Mode.
ON/OFF-C
ONTROLLER MODE
ON/OFF-CONTROLLER Mode is self-resetting. Pressing ACK has no effect on relay
coils. Used when automated action is required.
