Description

The 86691-00680-350-10 is an eddy current proximity probe from the Bently Nevada 86691 series, designated 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 1.0 meter total cable length.

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.

Overview Manuals Application Notes Product Applications Mechanical Insertion & Gapping

Features:

  • Industrial vibration probe for rotating machinery
  • Rugged stainless-steel probe construction
  • Shielded industrial cable for reliable signal transmission
  • Compatible with Bently Nevada monitoring systems
The Bently Nevada 86691-00680-350-10 is an industrial vibration probe developed for continuous monitoring of rotating machinery. It is designed to detect mechanical vibration and provide a stable signal for machinery protection and condition monitoring systems installed on critical assets.

The probe is intended for permanent installation on industrial equipment where continuous vibration measurement is required. Its rugged construction allows operation in demanding environments commonly found in power generation, oil and gas, petrochemical, mining, and heavy manufacturing facilities. The stainless-steel housing and industrial-grade cable provide resistance to vibration, moisture, dust, and mechanical stress encountered during long-term service.

The 86691-00680-350-10 Bently Nevada Vibration Probe may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Bently Nevada 86691-00680-350-10 Vibration Probe Manuals, Datasheets, Drivers, Link 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.
The 86691-00680-350-10 is calibrated for AISI 4140 steel targets. Interchangeability error is maintained within ±5% without field recalibration when used with matched system components. The probe achieves a typical resolution of 0.1 µm (4 µin) and a frequency response of 0 to 10 kHz (-3 dB).
This probe is applicable in shaft vibration monitoring, axial position measurement, differential expansion monitoring, and rotational speed detection on turbomachinery, pumps, motors, compressors, and generators. 
  • Power Generation: Deployed in thermal/nuclear/combined-cycle stations to safeguard generator sets
  • Oil & Gas: Implemented across upstream/downstream machinery to mitigate catastrophe risks
  • Petrochemical Refining: Protects continuous-duty process compressors from severe structural cross-contact
  • Steam Turbines: Tracks differential growth between fast-heating rotor and slower-expanding stator casing
  • Gas Compressors: Monitors axial changes and heavy shaft displacements in industrial compressors
  • Fluid-Film Bearings: Provides long-range non-contact positioning for massive rotating assemblies

Inspect the Target Area: Ensure the shaft surface is clean, free of scratches, rust, or deep machining marks.Thread the Probe: Thread the probe slowly by hand into the housing block or bracket until the tip gently touches the target surface. Do not use a wrench yet.Back Out to Initial Gap: Once touch-contact is made, back the probe out counter-clockwise roughly 1.5 to 2 full turns. This provides a safe physical baseline clearance (roughly 1.5 to 2.0 mm).

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 86691-00680-0350-10-00?

    +
    The Bently Nevada 86691-00680-0350-10-00 is an industrial vibration probe accelerometer used for machinery condition monitoring.
  • What type of sensor is the 86691-00680-350-10?

    +
