Features:
- Base model series for a heavy-duty, turbine-grade Vibration Probe Assembly engineered for extreme operating conditions
- This indicates that the probe complies with the electronic compliance requirements of international hazardous materials regulations such as ATEX, IECEx, and CSA
- Designed specifically for GE industrial gas turbines, it is used to monitor key rotational parameters such as axial displacement and radial shaft vibration
The 86691-00680-0350-90-05 is a high-performance eddy current vibration probe designed for heavy industrial machinery, serving as a core front-end sensor for asset condition monitoring and protection systems. Functionally, this product is designed for continuous, high-precision online monitoring of radial vibration (shaft vibration), axial displacement, and speed/critical phase in critical rotating machinery such as steam turbines, compressors, large fans, water pumps, and generator sets.
As a highly customized industrial measurement component, this model's specific suffix (e.g., -0350-90-05) corresponds to extremely harsh environmental adaptability and precise hardware specifications (including specially lengthed cables, unthreaded housings, or armored hoses). The probe boasts superior electromagnetic interference (EMI) immunity and excellent resistance to high pressure and chemical corrosion, maintaining stable operation even after prolonged immersion in industrial lubricating oil environments with pressures reaching several megapascals.
The 86691-00680-0350-90-05 Bently Nevada Proximity vibration probe may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
1.Dynamic Motion Tracking: Measures the continuous, real-time orbital motion of the high-speed turbine rotor within its journal bearings (X-Y orthogonal positioning).
2.Early Defect Detection: Detects and resolves problems before minor shaft imbalances, structural misalignments, mechanical loosening, or bearing wear escalate into catastrophic equipment failure.
3.Rotor Drift Prevention: Monitors the axial displacement of the main rotor shaft relative to the stationary thrust bearing (axial float).
4.Catastrophic Collision Prevention: Crucial in gas turbines, ensuring that rotating compressor or turbine blades do not drift back and forth and collide with stationary stator blades.
5.Phase Angle Reference: Used as a reference sensor to track timing marks per revolution on the rotating shaft.
6.Diagnostic Data: Crucial for calculating rotational speed (RPM) and accurately separating vibration frequencies during machine startup, shutdown, and steady-state operation.
7.GE Frame Series Gas Turbines: Designed specifically for the specific mechanical dimensions and thread requirements of the GE Frame 5, 6, 7, and 9 gas turbines.
8.High temperature resistance: The extended housing (-00680) and robust blade tip design allow it to penetrate deep into the high-temperature inner casing of a gas turbine, where standard commercial sensors would quickly melt or fail.
ATEX (Europe): Certified for use in Class 1 and Class 2 gas/vapor environments. Typically marked as Ex ia IIC T4...T1 Ga (intrinsically safe, suitable for Zones 0/1).
IECEx (Global): Certified according to IECEx standards, suitable for explosive atmospheres, and recognized by international regulatory bodies.
CSA/NRTL/C (North America): Certified for use in Class 1, Zone 1 (Groups A, B, C, D), and Zone 0/1 hazardous areas.
Compliant with API 670: Complies with the American Petroleum Institute (API) 670 standard for mechanical protection systems. This standard sets stringent accuracy, linear range limits, and reliability thresholds for vibration and axial position tracking of critical turbomachinery.
CE Mark: Fully compliant with European Economic Area directives, ensuring compliance with important health, safety, and environmental protection regulations.
