Sulfur Hexafluoride SF6 100 Vol.-.%

Product catalog summary

Product Overview: The FLOWEVO Infrared Gas Sensor by smartGAS Mikrosensorik GmbH is designed for detecting Sulfur Hexafluoride (SF6) at 100 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 LED. It is characterized by low drift and is suitable for applications such as SF6 leakage detection, tracer gas measurement, and SF6 analysis in high voltage cables and transformers.

Specifications: The sensor uses a Non-Dispersive Infra-Red (NDIR) dual wavelength measurement principle, with a range of 0 to 100 Vol.-% FS. It requires a gas flow rate of 0.02 to 0.2 l/min and has mounting dimensions of 70 mm x 60 mm x 40 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 ≤ 12.7 s (standard) and ≤ 1.6 s (fast) for t90 (10 to 90% FS). The detection limit is ≤ 0.3 Vol.-% (standard) and ≤ 1.2 Vol.-% (fast). Repeatability is ≤ ± 0.5 Vol.-%, and linearity error is ≤ ± 1.4 Vol.-%. Long-term stability is ≤ ± 5.5 Vol.-% (zero) and ≤ ± 7.0 Vol.-% (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 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 Information: The sensor requires a test gas with a dew point of < +5°C, particle-free, and clean. Calibration is performed via software for zero and span adjustments. The document emphasizes the need for recalibration depending on application and ambient conditions. All specifications are subject to change without notice, and the document disclaims liability for any consequential losses or damages.
