NDIR Multi-Gas Sensor for CEMS CO2 20 Vol.-% // NO 2000 ppm // SO2 1000 ppm

Product catalog summary

Overview: The SILAREX NDIR Multi-Gas Sensor by smartGAS Mikrosensorik GmbH is designed for Continuous Emission Monitoring Systems (CEMS). It measures CO2, NO, and SO2 with high precision and is equipped with features like cross and pressure compensation, and Modbus communication.

Specifications:

Measurement Principle: Non-Dispersive Infra-Red (NDIR), dual wavelength.
Target Gases: CO2 (20 Vol.-%), NO (2000 ppm), SO2 (1000 ppm).
Flow Rate: 0.1 to 1.0 l/min.
Warm-up Time: Less than 2 minutes for start-up, less than 30 minutes for full specification.

Performance:

Response Time: Fast (<4s), Medium (<8s), Slow (<60s) at 0.7 l/min.
Digital Resolution: CO2 (0.01 Vol.-%), NO (1 ppm), SO2 (1 ppm).
Detection Limit: Varies by mode, with maximums of 0.03 Vol.-% for CO2, 17 ppm for NO, and 3 ppm for SO2.
Repeatability and Linearity Error: High precision with minimal deviation.
Long-term Stability: Maintains accuracy over 1000 hours of operation.

Environmental and Operational Conditions:

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

Electrical and Communication:

Supply Voltage: 24 V DC with a power consumption of less than 6 W.
Communication: Modbus ASCII/RTU via RS485.

Applications and Accessories: Suitable for emission monitoring, biogas, and process measurement. Accessories include insulation housing, gas cooler, particle filter, gas pump, and mounting equipment.

Additional Notes: The document emphasizes the importance of recalibration and notes that specifications may vary based on application and environmental conditions. For further details, users are encouraged to contact smartGAS directly.
