Duct Mount Carbon Dioxide Sensors
The DSCO2 Range: Featuring duct-mount NDIR Carbon Dioxide Sensors designed to monitor and measure vital indoor air quality parameters with precision and reliability. Engineered for use across residential, public, commercial, and light industrial settings, these sensors offer both digital and analog outputs along with exceptional performance features.
| Gas Type: Carbon Dioxide |
Product Information
- Analog: 1x 0-10V signals for CO2
- Digital: RS-485 Modbus RTU or BACnet MS/TP communication protocols.
- Relay: VFC (CO2): 1x SPST 70mA Max.
- Thermistor: 10K3 output for 3rd party temperature monitoring.
ABS (Automatic Background Calibration):
The DSCO2 sensor features Automatic Background Calibration (ABC) for simplified, maintenance-free calibration to fresh-air CO2 levels. Over a 24-hour period, the sensor monitors CO2 concentrations and automatically calibrates to the lowest detected value, assuming it represents fresh-air conditions. For optimal performance, the DSCO2 sensor must be exposed to fresh-air conditions on a regular basis.
