EmersonTM designs, manufactures, and tests its products to meet many national and international standards. Because these
instruments are sophisticated technical products, you must properly install, use, and maintain them to ensure they continue to
operate within their normal specifications. The following instructions must be adhered to and integrated into your safety program
when installing, using, and maintaining Emerson products. Failure to comply with instructions may result in: loss of life, personal
injury, property damage, damage to this instrument, and warranty invalidation.
•Read all instructions prior to installing, operating, and servicing the product.
•If you do not understand any of the instructions, contact your Emerson representative for clarification.
•Follow all warnings, cautions, and instructions marked on and supplied with the product, including this manual.
•To ensure proper performance, use only informed and qualified personnel to install, operate, update, program, and
maintain the product.
•Install equipment as specified in the installation instructions of the appropriate instruction manual and per applicable local
and national codes. Connect all products to the proper electrical and pressure sources.
•Use only factory documented components for repair. Tampering and unauthorized substitution and parts can affect
product performance and cause unsafe operation of your process.
WARNING!
RISK OF ELECTRICAL SHOCK
1.Disconnect the main power wire from the separate power source before servicing.
2.Do not operate or energize instrument with case open!
3.Wiring connected in this box must be rated at least 240 Vac and 14 gauge.
4.Non-metallic cable strain reliefs do not provide grounding between conduit connections! Use grounding type bushings and
jumper wires.
5.Seal unused cable conduit entries securely with non-flammable enclosures to provide transmitter's enclosure integrity in
compliance with personal safety and environmental protection requirements. Seal unused conduit openings with Type 4X or
IP66 conduit plugs to maintain the ingress protection rating (Type 4X) of transmitter's enclosure.
6.Operate only with front panel fastened and in place.
7.For safety and performance, connect and properly ground the system through a three wire power source.
8.Proper use and configuration is your responsibility.
9.Install all protective equipment covers and safety ground leads after installation. Failure to install covers and ground leads
could result in serious injury or death.
10.Provide local ground connection to the RosemountTM CX1100 in order to avoid electric shock. The ground conductor should
be equal to or greater than 16 AWG for a copper conductor in free air or 12 AWG for an enclosed copper conductor.
11.Disconnect and lock out power before connecting the power supply.
12.Install all protective covers and safety ground leads after installation. Failure to install covers and ground leads could result
in serious injury or death.
13.Disconnect and lock out power before working on any electrical components. There is voltage up to 240 Vac. Verify the
reliability and continuity of the grounding of the probe connection before powering the equipment.
14.To meet the Safety Requirements of IEC 61010-1 (EC requirement) and ensure safe operation of the equipment, make a
connection to the main electrical power supply through a circuit breaker (max 10A) which will disconnect all currentcarrying conductors during a fault situation. The circuit breaker should also include a mechanically operated isolating
switch. If it does not, then locate another means of disconnecting the supply from the equipment close by. Circuit breakers
or switches must comply with a recognized standard, such as IEC 60947.
15.Ensure that all equipment doors are closed and protective covers are in place, except when maintenance is being performed
by qualified people, to prevent electrical shock and personal injury.
CAUTION!
•If the ducts will be washed down during outage, make sure to power down the probes and remove them from the wash
area.
•When replacement parts are required, ensure that qualified people use replacement parts specified by Emerson.
Unauthorized parts and procedures can affect the product's performance, place the safe operation of your product at risk,
and void your warranty. Look-alike substitutions may result in fire, electrical hazards, or improper operation.

1General information
1.1Overview
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
1.2Rosemount CX1100 Oxygen Probe and
Transmitter
A complete Rosemount CX1100 In Situ Oxygen Transmitter system includes a probe and
remote transmitter. Raw signals (sourced from the heater thermocouple and oxygen
sensor) and power are transmitted between the Rosemount CX1100 probe and the
Rosemount CX1000 remote transmitter, interconnect wiring consisting of nine
conductors. The specifications of the wiring arrangement can be found in Chapter 3. If
following the specifications, 200 ft (61 m) is the maximum cable length allowed.

WARNING!
ELECTRIC SHOCK
Install all protective equipment covers and safety ground leads after installation. Failure to
install covers and ground leads could result in serious injury or death.
CAUTION!
EQUIPMENT DAMAGE
Do not allow the temperature of the Rosemount™ CX1100 Probe electronics to exceed 194 °F
(90 °C) or damage to the unit may result.
2.1Probe installation
Install
A weld plate for welding to the flue gas duct can be supplied for new installations.
1.If using the standard square weld plate (Figure 2-2) or an optional flange mounting
plate, weld or bolt the plate onto the duct.
The through hole diameter in the stack or duct wall and refractory material must be
at least 2.5 in. (63.5 mm).
2.Insert probe through the opening in the mounting flange and bolt through the
probe gasket and flange.
For horizontal installations, the breather port must be oriented such that it is facing
downward.
