The 86691-00680-0350-90-05 is a non-contact eddy current proximity probe. This model belongs to the classic Bently Nevada 7200 Series (8mm) as an OEM custom variation, utilized for the asset protection and condition monitoring of heavy rotating machinery. By measuring the static and dynamic gaps between the probe tip and the observed shaft, it converts these distances into proportional voltage signals to provide early warnings of mechanical faults.
Fully meets the technical specifications required by the American Petroleum Institute API 670 standard for machinery protection systems
As an OEM variation of the classic 7200 series, it connects directly and seamlessly with existing Bently Nevada 3300 and 9000 monitoring racks
Utilizing eddy current technology, it implements non-contact monitoring for both static axial displacement (thrust) and dynamic shaft vibration
The 7200 5mm and 8mm Proximity Transducer Systems are non-contacting gap-to-voltage transducer systems that measure static as well as dynamic distances between the probe tip and the observed target. The general application is any requirement for an accurate, non-contacting displacement measurement. However, the most common use is for shaft position and vibration measurements on rotating and reciprocating machinery.
These products are suitable for use with virtually any machine type including gas and steam turbines, compressors, pumps, centrifuges, electric motors, and generators. The systems offer 80 mils (2 mm) of linear measuring range and are compatible with API 670 requirements. A system consists of a probe with integral coaxial cable, an extension cable, and a Proximitor Sensor. All 7200 proximity transducer systems are compatible with 3300 and 9000 Monitoring Systems.

Petrochemical & Refining
Monitoring axial displacement and radial vibration of large reactor circulation pumps in high-temperature, high-pressure refining environments to ensure continuous process operation.
Thermal Power Generation
Continuously monitoring rotor eccentricity, shaft vibration, and shaft runout of large steam turbine-generator sets to prevent catastrophic friction between blades and bearings.
Nuclear Power Generation
Monitoring large pump sets in conventional islands and auxiliary systems to provide early equipment fatigue warnings through high-precision vibration analysis.
Hydroelectric Power Generation
Monitoring bearing swing and unit vibration of large vertical or horizontal hydro-generator sets to optimize hydraulic distribution and prevent cavitation damage.
Wind Power Generation
Installed inside the wind turbine nacelle to monitor the mechanical status of low-speed and high-speed shafts in high-power gearboxes and generators, reducing costly offshore or high-altitude maintenance.
Steel & Metallurgy
Monitoring vibrations of blast furnace blowers and rolling mill main drive shafts in extreme dust and high-temperature environments to avoid sudden production shutdowns that cause molten steel solidification.
During the use of the 86691-00680-0350-90-05 vibration probe, the most critical steps are ensuring a rigid mounting, strictly matching the system cable length, and regularly calibrating the gap voltage.
Meanwhile, it is essential to protect cables against wear, water, and oil, while avoiding strong electromagnetic interference to guarantee absolute accuracy in industrial monitoring data.
The Bently Nevada 86691-00680-0350-90-05 is a non-contact proximity probe specifically designed for the precise measurement of shaft vibration and axial displacement in rotating machinery, such as steam turbines and compressors. Featuring an integrated stainless steel braided armored cable, it provides exceptional wear resistance, oil immunity, and EMI shielding. This ensures high-fidelity transmission of micron-level mechanical displacement signals, making it a critical sensor spare part for safeguarding heavy industrial assets.
This is an industrial vibration probe/accelerometer manufactured by Bently Nevada, primarily used for continuous vibration monitoring of heavy machinery.
What is the primary application of 86691-00680-0350-90-05?
It is used for machinery condition monitoring (e.g., turbines, compressors, pumps, and motors) to predict potential mechanical failures by capturing vibration signals.
How does the 86691-00680-0350-90-05 probe work?
It typically based on piezoelectric or eddy-current principles, converting physical shocks from mechanical vibration into proportional electrical signals (voltage or current).
What is the frequency response range of 86691-00680-0350-90-05?
Its typical frequency response ranges from 1 Hz to 10 kHz, covering low-frequency to high-frequency fault characteristics of most rotating machinery.
How to correctly install 86691-00680-0350-90-05?
It is rigidly mounted to the bearing housing or machine casing using dedicated mounting threads (such as M12 or standard bolts) to ensure accurate vibration transmission.
