Johnson Controls is licensed to integrate the silicon-based CARBOCAP® sensor into HVAC or Building Automation Systems. Integrating this sensor delivers several advantages: high accuracy, excellent stability, negligible temperature dependence, and ease of installation. Due to the long-term stability, maintenance costs are reduced.
The structure of the diffusion-aspirated, single-beam dual-wavelength sensor is remarkably simple. It consists of an Infrared (IR) source, a sample cell, a tunable-interference filter, and an IR detector. The tunable-interference filter enables measurements at two wavelengths. As a result, references are measured accurately, without the typically broad tolerances inherent in dual-beam sensors.
Dust, water vapor, and most chemicals do not affect the measurement accuracy of the sensor. No special software compensation patches are necessary, and the device requires no maintenance.
