Series Description
The Kele Model CD-A Carbon Dioxide Sensors represent a new level of economy in reliable non-dispersive infrared CO2 detection. Designed for use in building automation systems, BAS, the gas sensors measure environmental carbon dioxide levels for use in demand-controlled ventilation and air-quality monitoring scenarios in accordance with ASHRAE standards. Fully isolated analog outputs and a convenient center wiring terminal make installation both simple and trouble-free. The analog output is jumper-selectable, 4-20 mA or 0-10 VDC, over the industry standard 0-2000 ppm CO2 range. Models are also available with an optional LCD display and/or control relay with adjustable setpoint.
