The Bently Nevada 31000-28-10-00-133-03-02 is a precision proximity probe for non-contacting displacement and vibration monitoring in 3300 Transducer Systems.
The Bently Nevada 31000-28-10-00-133-03-02 is a specialized proximity probe designed for critical industrial asset protection. This eddy current sensor measures the physical gap between the probe tip and a rotating shaft without making contact. It plays a vital role in Turbine Supervisory Instrumentation (TSI) by monitoring radial vibration and axial thrust. Consequently, this probe helps plant operators detect early signs of mechanical wear or misalignment. It provides a steady data stream to prevent catastrophic equipment failure in high-speed environments.

Industrial environments often subject sensors to extreme heat, moisture, and chemical exposure. This probe features a ruggedized design to withstand these challenging conditions. The probe tip uses high-strength polyphenylene sulfide (PPS) to resist fluid penetration. Furthermore, the stainless steel body ensures long-term structural integrity against mechanical stress. This model remains highly stable even when exposed to fluctuating temperatures and pressurized oil environments. Reliable data collection continues uninterrupted, ensuring maximum uptime for power plants and refineries.
This proximity probe utilizes gold-plated connectors to ensure low electrical resistance and superior signal quality. The 31000-28-10-00-133-03-02 is fully compatible with Bently Nevada’s 3300 XL Proximitor sensors and extension cables. This compatibility allows for easy integration into existing 3500 series machinery protection racks. Operators can swap components quickly because the system maintains a standardized scale factor. The design effectively minimizes electromagnetic interference (EMI) to provide clean vibration waveforms for diagnostic software.
Critical rotating assets across the energy and manufacturing sectors rely on this specific transducer. It is frequently installed on steam turbines, gas compressors, and large process pumps. The probe meets stringent API 670 standards for machinery protection systems. Its precise linearity and frequency response make it ideal for both shaft position and vibration monitoring. By using this genuine Bently Nevada component, facilities maintain the highest level of safety and operational efficiency.
