NDIR Multi-Gas Sensor for CEMS CO2 20 Vol.-% // CO 1000 ppm

Product catalog summary

Overview: The SILAREX NDIR Multi-Gas Sensor by smartGAS Mikrosensorik GmbH is designed for Continuous Emission Monitoring Systems (CEMS), capable of measuring CO2 up to 20 Vol.-% and CO up to 1000 ppm. It features dual active measurement channels, is pre-calibrated, and includes on-board cross and pressure compensation. Communication is facilitated via Modbus ASCII/RTU.

Specifications:

Measurement Principle: Non-Dispersive Infra-Red (NDIR), dual wavelength.
Measurement Range: CO2: 0 to 20 Vol.-%, CO: 0 to 1000 ppm.
Flow Rate: 0.1 to 1.0 l/min.
Response Time: Fast: < 4s, Medium: < 8s, Slow: < 60s at 0.7 l/min.
Digital Resolution: CO2: 0.01 Vol.-%, CO: 1 ppm.
Repeatability: CO2: ≤ ± 0.06 Vol.-%, CO: ≤ ± 6 ppm.
Linearity Error: CO2: ≤ ± 0.1 Vol.-%, CO: ≤ ± 10 ppm.
Long Term Stability: Zero: CO2: ≤ ± 0.01 Vol.-%, CO: ≤ ± 5 ppm after 1000 hours.

Environmental Conditions:

Operating Temperature: +10 to +40 °C with thermal isolation.
Storage Temperature: -20 to +60 °C.
Humidity: 0 to 95% relative humidity, non-condensing.
Air 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.
Inrush Current: < 400 mA.
Output Signal: Modbus ASCII/RTU via RS485.

Accessories and Options: The sensor can be equipped with insulation housing, gas cooler, particle filter, gas pump, and mounting equipment. It is available in 2-channel and 3-channel designs.

Recommendations: Initial and periodic recalibration is recommended depending on application and ambient conditions. For more information, visit the smartGAS website or contact their sales team.
