Carbon Dioxide Detector-Transmitter
- Stable long-life optical NDIR sensor
- Range 0...10 000 or 0...50 000 ppm CO
- Resolution 1 ppm or 100 ppm CO2
- Two SPST relays (option)
- 2 × 4-20 mA or 0-10 V, RS485
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 a fully calibrated and temperature compensated 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 relays with closing contact (optional) may be used for remote signalling or concentration control. Two alarm set-points are user settable.
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.
