Infrared gas Sensor Methane CH4 50 Vol.-% for Biogas application

Product catalog summary

Product Overview: The FLOWEVO infrared gas sensor by smartGAS Mikrosensorik GmbH is designed for biogas applications, specifically for detecting Methane (CH4) at concentrations up to 50 Vol.-%. It features a pre-calibrated, compact design with a 3/5 mm gas line connector and operates on a 3.3–6 V DC supply voltage. The sensor supports Modbus ASCII or RTU communication and indicates status via an LED.

Specifications: The sensor uses a Non-Dispersive Infra-Red (NDIR) dual wavelength measurement principle. It has a measurement range of 0 to 50 Vol.-% Full Scale (FS) and requires a gas flow rate of 0.1 to 1.0 l/min. The device dimensions are 76 mm x 30 mm x 50 mm, with a warm-up time of less than 2 minutes for start-up and less than 30 minutes for full specification.

Performance: The digital resolution is 0.01 Vol.-%, with a response time of ≤ 9.9 seconds for standard and ≤ 0.7 seconds for fast response at 0.7 l/min. The detection limit is ≤ 0.2 Vol.-% for standard and ≤ 0.38 Vol.-% for fast response. Repeatability is ≤ ± 0.4 Vol.-%, and linearity error is ≤ ± 0.6 Vol.-%. Long-term stability is ≤ ± 0.6 Vol.-% for zero and ≤ ± 1.8 Vol.-% for span over 1000 hours.

Environmental and Electrical Parameters: The sensor operates within a temperature range of 0 to +50 °C and can be stored between -20 to +60 °C. It functions under air pressure conditions of 800 to 1150 hPa and ambient humidity of 0 to 95% (non-condensing). The supply voltage ranges from 3.3 V to 6.0 VDC, with a peak supply current of < 400 mA at 3.3 V and < 240 mA at 5.0 V. The average power consumption is < 800 mW.

Additional Features: The sensor includes calibration software and supports zero and span calibration via software. It is recommended to recalibrate at first initiation and periodically based on application and ambient conditions.
