Product Data: SC311 Infrared Combustible Gas …

1 SC311 Infrared Combustible Gas SensorFGD-PDS- SC311 - Infrared - Combustible -Gas-SensorProduct data SheetJuly 2016SC311 Infrared Combustible Gas SensorsMillennium II Series SensorsThe SC311 delivers the latest technologyadvancements in Infrared sensing of flammablegases in a rugged package designed for the mostextreme industrial environments. Hydrocarbongas LEL detection is fast, reliable and highlyaccurate with only periodic bump testingrecommended and a simple annual calibrationsequence. A full 5 year warranty is included witha typical sensor life of 8 10 years.

2 Lowest power consumption available Long range (+2,000 ft.) sensor separation Industry leading 5 year sensor warranty Field selectable gas curves available Immune to poisoning - standard gases detected include methane, propane, butane, and ethyleneST3 Sensors shown with JB-MPD-A/S. Very fast response and highly accurate Designed to perform in the most extreme industrial environmentsSingle or Dual Channel Transmitter AvailableThere s no longer the need to purchase multiple gas specifi cdetectors. You have the option to utilize 1 or 2 toxic and/orcombustible gas sensors on a single Millennium II transmitterand easily mix and match any of our sensor Designed for Durability & PerformanceHigh resolution, dual-beam optics are employed in the sensordesign which eliminates refl ective surfaces preventing fouling,fogging or misalignment.

3 Not only does this provide enhancedoverall performance but it also means low power consumptionwhich equals cost savings and more reliable Operation & Advanced DiagnosticsContinuous self-check for several performance parameters aswell as environmental compensation for temperature, pressureand humidity maintains a high level of sensor performance Infrared Combustible Gas SensorJuly Combustible Gases [% LEL] InfraredP/N: SC311 (A/S)-100-ASSYP erformanceResponse TimeT50 sT60 7 sT90 11 sAccuracy 5 % LELD etection Range0 100 % LELG ases Detected*.
