🏭 Where Heat Meets Precision
Gas Turbine Hot Sections: Monitor bearing vibration adjacent to combustion chambers and turbine sections where ambient temperatures routinely exceed 300°F—environments that would destroy standard sensors within hours.
Steam Turbine Applications: Track shaft position and vibration near high-pressure steam inlets where radiant heat and superheated steam create hostile measurement conditions.
Kiln and Furnace Monitoring: Measure rotating equipment in cement kilns, steel mill furnaces, and glass manufacturing where process heat radiates to nearby machinery.
Petrochemical Hot Processes: Surveil pumps and compressors handling high-temperature hydrocarbons, thermal cracking units, and reformer systems operating above 400°F.
⚡ Engineering Intelligence
The challenge in high-temperature monitoring isn't just sensor survival—it's maintaining calibration accuracy as temperatures fluctuate. This sensor employs temperature-compensated electronics and thermally-stable coil materials that preserve the factory calibration curve across the entire operating range.
Unlike sensors that require field recalibration after thermal cycling, the 3300/20-01-01-01-00-00 maintains its measurement integrity through thousands of heat-up and cool-down cycles. This translates to lower maintenance costs and higher confidence in your condition monitoring data.
🔌 System Integration
Compatible with Bently Nevada 3300 XL proximitor systems and 3500 rack monitoring platforms. The sensor's output characteristics match standard proximity probe specifications, allowing drop-in replacement without system reconfiguration or recalibration of downstream electronics.
Can be used with high-temperature extension cables (rated to 260°C) when additional cable length is required. Integrates with existing machinery protection systems, DCS inputs, and vibration analysis software without special signal conditioning.
✅ Quality Validation
Every sensor undergoes thermal cycling testing from -40°C to +200°C to verify calibration stability and eliminate infant mortality failures. Factory calibration includes high-temperature verification at 175°C to ensure accuracy across the full operating envelope.
Includes individual calibration certificate with temperature-compensated curves, serial number traceability, and material certifications for quality assurance documentation.
