Description

Carbon Dioxide detector-transmitter E2648-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.

To connect the detector-transmitter to safety or building automation systems use two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol. We recommend to set the output scale within 20-100% of the detection range.

Two relays with closing contact (option) may be used for remote signalling or ventilation control. Two alarm set-points are user settable within 5-95% of the detection range.

The device is available with either attached or remote sensor probe (default cable length is 3 m).
