Description
The 86691-00680-0350-90-05 is an eddy current proximity probe from the Bently Nevada 86691 series,as a vibration probe for machinery condition monitoring applications. It is configured with a 6.8 mm probe tip diameter, 3.5 inch overall case length, and 9.0 meter total cable length with multiple hazardous area approvals.
The probe operates as the sensing element of an eddy current transducer system, detecting the distance between the probe tip and a conductive target surface through electromagnetic induction. The 6.8 mm probe tip diameter provides a linear measurement range of approximately 1.0 mm (40 mils) with a standard gap setpoint of 0.5 mm (20 mils). System sensitivity is 7.87 V/mm (200 mV/mil) with ±5% tolerance, delivering an output voltage proportional to the probe-to-target gap.

The Bently Nevada 86691-00680-0350-90-05 is an industrial vibration probe designed for continuous monitoring of rotating machinery. It features a 9.0 m integrated cable, supports CSA, ATEX, and IECEx hazardous-area approvals (Option 05), and is intended for use with Bently Nevada machinery protection systems to provide reliable vibration measurement for turbines, compressors, pumps, motors, and generators.
- Turbines: Monitors steam, gas, and hydro-turbine generator systems
- Compressors: Monitors large-scale axial, centrifugal, and industrial air compressors
- Pumps/Motors: Monitors process pumps, boiler feed pumps, and high-horsepower electric motors
- Balance-of-Plant: Monitors cooling tower fans, blowers, gearboxes, and agitators
This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Check the Clearances: Ensure the target shaft area is smooth, clean, and free of scratches. The installation hole must be tapped cleanly to match the probe's thread pitch.
Mounting Bracket Setup: Insert the probe into its mounting sleeve, bracket, or housing.Physical Insertion: Manually thread the probe into the mounting hole until the tip gently touches the shaft target.
Technical notes
The probe body is rated for continuous operation from -51°C to +177°C (-60°F to +351°F), with the cable rated for the same temperature range. The shielded coaxial cable construction provides electromagnetic interference protection for the low-level signal transmitted from the probe to the proximitor. The cable is rated for IP68 submersibility and withstands pressures up to 500 psi (34.5 bar).
FAQs
-
What is the primary function of this part?
+This component acts as a proximity transducer to monitor the mechanical health of high-speed rotating machinery. It measures critical metrics like radial vibration, shaft axial displacement, and rotational speed (Keyphasor) without making physical contact with the shaft. -
What is the 86691-00680-0350-90-05?
+The Bently Nevada 86691-00680-0350-90-05 is a specialized, industrial non-contacting eddy current proximity vibration probe used primarily for condition monitoring and machinery protection in rotating equipment. -
What is the proper gap voltage for setting up this probe?
+When properly gapped in its linear range over a standard 4140 steel target, the normal gap voltage should read between −9 VDC and −11 VDC. -
Why does this system utilize a negative voltage output?
+Bently Nevada proximity transducers famously operate on a -24 VDC power supply loop. This convention dates back to early solid-state design history where P-N-P style transistors were fundamentally more cost-effective and resilient against field grounding interference than N-P-N alternatives.
