Rosemount Analytical CX1100 Service Manual

Combustion Control Solution for
Commercial and Small Industrial Boilers

CHALLENGE

With increasing environmental requirements, users of commercial and
small industrial boilers are faced with escalating compliance demands,
which in turn, increase the need for measurement and control. Some do

not currently measure combustion ue gas, leaving themselves open
to regulatory as well as energy inefciency problems. Those who are

measuring, may not be aware of available technologies that offer a higher
degree of accuracy and longer sensor life.

WHAT IF...

...boiler efficiency could be
improved with a high-quality
combustion control solution
designed without the cost and
complexity?

… combustion flue gas
measurement could be achieved
with a system that offers ease of
use and simplified service and
maintenance?

OUR SOLUTION

The Rosemount™ CX1100 In-Situ Oxygen Transmitter is a combustion
control solution designed to improve boiler efciency and meet

environmental regulatory requirements for small and midsize boiler users,

and offers ease of use, economy, and simplied maintenance. Featuring
the patented Rosemount oxygen sensing zirconia cell, it offers the same

sensor reliability found in large industrial technology, but is built to
the requirements of users in applications, such as, food and beverage,
manufacturing, and commercial and institutional power and heating.

HOW IT WORKS

• Zirconia sensing cell and the all-welded probe improve reliability
by eliminating leak points

• Does not use piped reference air which keeps installation and
maintenance costs low

• Offers an easy-replacement design that enables simplied service

• Remote transmitter architecture allows for fast conguration
and calibration that includes a large, multi-function display
with diagnostics
