The Bently Nevada 350800-01-180-00 is a precision gas sensor engineered for continuous combustible and hazardous gas detection in critical rotating machinery environments. As part of the renowned 3500 Series Machinery Protection System, this sensor integrates seamlessly into plant-wide safety and condition monitoring architectures — delivering real-time gas presence data that protects personnel, assets, and uptime.
Where This Product Is Used
This sensor is specified by process engineers and reliability teams across the most demanding industrial environments:
- Oil & Gas Upstream: Wellhead platforms, compressor stations, and gas gathering facilities where hydrocarbon leak detection is safety-critical.
- LNG & Petrochemical Plants: Turbine enclosures, heat exchanger bays, and pump rooms requiring continuous methane/LEL monitoring.
- Power Generation: Gas turbine packages and combined-cycle plants where hydrogen or natural gas leaks must be detected before ignition thresholds are reached.
- Offshore Platforms: ATEX/IECEx-rated zones where certified gas detection is mandated by classification societies (DNV, ABS, Lloyd’s).
- Chemical Processing: Reactor buildings and solvent storage areas with volatile organic compound (VOC) exposure risk.
- Pipeline Compression Stations: Integrated with SCADA and ESD systems for automated shutdown on gas detection events.

Application-Specific FAQ
Q: Is the 350800-01-180-00 compatible with older 3500 rack generations?
A: Yes. The 3500 Series maintains backward compatibility across rack generations. Confirm firmware version of your 3500/62 module with your site engineer.
Q: Can this sensor be used in Zone 1 hazardous areas?
A: The 3500 gas sensor system is designed for hazardous area use. Verify the specific ATEX/IECEx certificate applicable to your installation zone with the OEM datasheet.
Q: What does the “-180-00” suffix mean?
A: The suffix encodes the sensor cable length — 180 feet (approximately 54.9 meters). This allows the sensor head to be located remotely from the 3500 rack in the field.
