Carbon Dioxide Detector-Transmitter E2638-CO2-10K
- Stable long-life optical NDIR gas sensor
- Range 0...10 000 ppm CO2
- 2 × 4-20 mA or 0-10 V, RS485
- Ambient pressure compensation option
- Attached or remote sensor options
- Relay or LCD indicator option
Carbon Dioxide transmitter E2638-CO2-10K 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 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.
The device is available with either attached or remote sensor probe (default cable length is 3 m).
A version with an LCD indicator is available.
