Methane CH4 50 Vol.-%

Product catalog summary

Product Overview: The FLOWEVO Infrared Gas Sensor for Methane (CH4) by smartGAS Mikrosensorik GmbH is a pre-calibrated, compact sensor designed for gas analysis, process control, and environmental monitoring. It features a 3/5 mm gas line connector, operates on a 3.3–6 V DC supply voltage, and supports Modbus ASCII or RTU communication.

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

Measuring Response: The digital resolution is 0.01 Vol.-%, with a response time of ≤ 9.9 s (standard) and ≤ 0.7 s (fast) at 0.7 l/min. The detection limit is ≤ 0.2 Vol.-% (standard) and ≤ 0.38 Vol.-% (fast). Repeatability is ≤ ± 0.4 Vol.-%, and linearity error is ≤ ± 0.6 Vol.-%.

Stability and Dependence: Long-term stability for zero is ≤ ± 0.6 Vol.-% over 1000 hours, and for span, it is ≤ ± 1.8 Vol.-%. Temperature dependence is ≤ ± 0.1 Vol.-% per °C for zero and ≤ ± 0.2 Vol.-% per °C for span. Pressure dependence is +0.100% of actual reading per hPa, and flow rate dependence is ≤ ± 0.1 Vol.-% per 0.1 l/min.

Electrical Parameters: The sensor operates on a supply voltage of 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. Inrush current is < 600 mA, and average power consumption is < 800 mW. It provides a digital output signal via Modbus ASCII/RTU.

Climatic Conditions: The operating temperature range is 0 to +50 °C, with a storage temperature range of -20 to +60 °C. It can operate in air pressure conditions of 800 to 1150 hPa and ambient humidity of 0 to 95% relative humidity (non-condensing).

Additional Information: The document notes that specifications are subject to change and advises consulting smartGAS for specific applications and recalibration recommendations. The data provided is for guidance only and does not constitute a specification or offer for sale.
