CD-Pxx-00-0 Series Duct Mount CO2 Transmitter Code Number Description

Refer to the CD-Pxx-00-1 Series Duct Mount CO2 Transmitter Product Bulletin (LIT216525) for important product application information.

The silicon-based CARBOCAP® sensor delivers high accuracy and long-term measurement stability (±100 ppm) over a 5-year period without calibration. The diffusion-aspirated, single-beam, dual-wavelength sensor structure is remarkably simple. It consists of an 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 permit 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.

• CARBOCAP silicon, micro-machined construction provides reliable CO2 measurement in duct environments

Features

• DCV strategies offer a potential for 10 to 70% energy savings

• CARBOCAP single-beam, dual-wavelength design provides superior performance compared to other technologies

Code No. LIT-1900157

CD-Pxx-00-0 Series Duct Mount CO2 Transmitter

Description

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 HVAC applications. These compact, duct mounted devices offer a choice of 0 to 10 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. • calibration reliability offers 5 years of reliable calibration

• adjustable duct probe depth permits optimal placement of sensing tip in a duct

• optional features offer relay output for fan control

Applications

The new CO2 transmitters are easy to install, offer a full 3-year warranty, and require no maintenance or field calibration. They are designed to work:

• in stand-alone mode

• in support of demand control ventilation (DCV)

• with fresh air and indoor air quality (IAQ) systems

• as part of any integrated Building Automation System (BAS)

• with rooftop air handling Economizer controls systems

• connected to Metasys® system or the AD-DME Series
