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

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

Johnson Controls offers a complete line of carbon dioxide (CO₂) modules that measure and transmit CO₂ levels ranging from 0 to 2,000 parts per million [ppm]. This compact device offers a choice o f 0 to 10 V or 0 to 20 mA output signals and features 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-wave length 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 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.

• stable infrared reference compensates for light-source drift
• CO₂ transmitters with DCV strategies offer a potential for 10 to 70% energy savings
• single-beam, dual-wavelength design provides superior performance compared to other technologies
• silicon, micro-machined construction provides reliable CO₂ measurement in harsh environments
