Carbon Dioxide detector-transmitter E2638R-CO2 is a member of new PluraSens® family of multifunctional measurement instruments.
Applications include HVAC and air quality control in public, office and industrial buildings, greenhouses, underground parkings, boiler houses, and other areas, where potentially toxic concentration of carbon dioxide can accumulate.
The instrument utilises optical NDIR gas sensor with excellent repeatability, stability and long lifetime. Ambient pressure compensation (in the range 0,5...2 bar of absolute pressure) is available as an option.
Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the detector to safety or building automation systems.
Two relays with closing contact may be used for remote signaling or ventilation control. The flashing LEDs and an internal buzzer (available as an option) give alarms as well at two set-points.
