NDIR Multi-Gas Sensor CO2 10 Vol.-% // SO2F2 100 ppm

Product catalog summary

Overview: The SILAREX NDIR Multi-Gas Sensor by smartGAS Mikrosensorik GmbH is designed for measuring CO2 and SO2F2 gases. It features two active measurement channels and is ready to use with calibration, cross and pressure compensation, and Modbus communication capabilities.

Specifications:

Measurement Principle: Non-Dispersive Infra-Red (NDIR), dual wavelength.
Target Gases: CO2 (10 Vol.-%) and SO2F2 (100 ppm).
Flow Rate: 0.1 to 1.0 l/min.
Mounting Dimensions: 336 mm x 30 mm x 50 mm.
Warm-up Time: Less than 2 minutes for start-up, less than 30 minutes for full specification.

Measuring Response:

Response Time (t90) at 0.7 l/min: Fast (<4s), Medium (<8s), Slow (<60s).
Digital Resolution: 0.001 Vol.-% for CO2, 0.01 ppm for SO2F2.
Detection Limit: Varies with mode, e.g., 0.016 Vol.-% for fast mode CO2.
Repeatability: ≤ ± 0.04 Vol.-% for CO2, ≤ ± 0.83 ppm for SO2F2.

Environmental and Operational Conditions:

Operating Temperature: +10 to +40 °C with thermal isolation required.
Storage Temperature: -20 °C to +60 °C.
Humidity: 0 to 95% relative humidity, non-condensing.
Pressure: 800 to 1150 hPa.

Electrical Inputs and Outputs:

Supply Voltage: 24 V DC ± 10%.
Power Consumption: <6 W with heater on, <1 W at stabilized temperature.
Digital Output: Modbus ASCII/RTU via RS485.

Additional Information: The sensor is made in Germany and is suitable for applications such as emission monitoring, biogas, process measurement, and fruit ripening. It is available in 2-channel and 3-channel designs. Regular recalibration is recommended depending on application and ambient conditions.
