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.
1.2 Rosemount 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 Wire. If following the
specifications, 200 ft. (61 m) is the maximum cable length allowed.
