1 General information
1.1 Overview
The Rosemount™ CX1100 In Situ Oxygen Transmitter provides a continuous, accurate
measurement of the oxygen remaining in flue gases coming from a combustion process.
Accurate measurements of furnace exhaust excess oxygen are critical for combustion
optimization, which result in reduced energy costs, increased safety, and lower emissions.
This product is intended for use for combustion applications only.
The Rosemount CX1100 probe contains a zirconia type oxygen sensor. At high
temperatures, zirconia produces an electrical potential that is proportional to the
difference in process oxygen concentration and ambient reference air. This voltage is
transmitted to the Rosemount CX1100 remote transmitter and output as an analog signal.
The sensor is mounted at the end of the probe tube which extends into a flue gas duct or
stack. Varying lengths of the probe are available to achieve desired insertion depths. The
probe tube also houses a heating element to precisely control the temperature of the
sensor, reducing errors induced by varying process temperatures.
General information
1.2 Rosemount CX1100 Oxygen Probe and
Transmitter

Calibration and maintenance
5 Calibration and maintenance
The Rosemount™ CX1100 In Situ Oxygen Transmitter can be calibrated in the installed
position without removing the instrument from the process duct and also while the
combustion process is online.Gas is applied to the sensor through the calibration gas
fitting. New Rosemount CX1100 In Situ Oxygen Transmitter systems are factory calibrated
and are generally acceptable for initial startup and operation. High accuracy can be gained
by calibrating a system during normal operating conditions. Emerson ™recommends
calibrating on a semi-annual to annual basis for most applications; however actual
calibration frequency may vary per process unit.
Calibrations are conducted using a two point calibration. Factory calibration uses 0.4% O
and 8.0% O2 gases with a balance of nitrogen and is therefore recommended. Calibration
gases with other oxygen concentrations are acceptable. If using different calibration gas
values, additional configuration through the Rosemount CX1100 Remote Transmitter is
required. Emerson does not recommend pure nitrogen as a calibration gas.
5.1 Procedure
The calibration of the Rosemount CX1100 Probe is initiated from the Rosemount CX1100
Remote Transmitter. The Rosemount CX1100 Remote Transmitter display prompts you
with the calibration instructions.
1. Press the x1 or x2 menu button on the Rosemount CX1100 Remote Transmitter
display to enter the probe.
2. Navigate, using Up and Down buttons to Setup; press Enter.
3. Navigate to Cal Gas values; press Enter.
4. Navigate to Cal Gas 1 and press Enter twice to highlight the value setting.
5. Use the Up and Down buttons to set Cal Gas 1 value and Left and Right buttons
to move to decimals setting.
6. After setting the correct value, press Enter and press Left to go to the Calibration
Setup for Cal Gas 2, Gas time, and Purge time settings.
2
7. After setting the values (0.4% O2, 8.0% O2, and 300s are the defaults), press Left to
go up to the Calibration submenu.
8. Navigate using the Up and Down buttons to Calibration and press Enter to start.
9. Follow the instructions on the display, manually applying calibration gases (0.4% and
8.0% O2 at 5 SCFH are recommended) to the calibration port.
10. After the calibration is finished, press Left and use the Up and Down buttons the
check the current and previous 10 calibrations log.
After completing the procedure, the Rosemount CX1100 software calculates new
calibration values and determines whether they meet an acceptance criteria. If successful,
the new calibration values automatically replace the previous values. In the event the
Reference Manual 23
Calibration and maintenance
calibration values do not meet the accepted performance criteria, the existing calibration
values remain in effect, and Emerson recommends replacing the Rosemount CX1100
Probe.
EQUIPMENT DAMAGE
Make sure that the calibration gas cap is replaced tightly after calibration is complete. Many
combustion processes operate at a slight negative pressure (draft pressure) and can draw
ambient air down the cal gas lines and into the sensing cell, causing a false elevated oxygen
reading. The same phenomenon is possible if the calibration gas hoses become degraded or
loose.
