Johnson Controls offers a complete line of carbon
dioxide (CO2) transmitters for measuring and
transmitting CO2 levels, ranging from 0 to 2,000 parts
per million (ppm), within Heating, Ventilating, and Air
Conditioning (HVAC) applications. These compact,
duct mounted devices offer a choice of 0 to10 V or
0 to 20 mA output signals and feature an optional relay
output with or without a digital display.
Johnson Controls® CO2 transmitters are easy to install
and to operate.
The silicon-based CARBOCAP® sensor delivers high
accuracy and long-term measurement stability
(±100 ppm) over a five-year period without calibration.
The diffusion-aspirated, single-beam, dual-wavelength
                                                                       Figure 1: Duct Mount CO2 Transmitter with

infrared (IR) source, a sample cell, an IR detector, and
a tunable interference filter that enables measurements
at two wavelengths. Reference measurements made
using a tunable interference filter eliminate the typical
weakness of dual-beam sensors and permits shifting
the optical pass band electronically. This innovative
design provides precise reference readings that
eliminate the typically broad deviation expected from a
traditional CO2 sensor.
