Overview Manuals Specifications Application Firmware and Updates Configuration

Features:

  • 6.80" case length and 3.50" unthreaded length for industrial durability.
  • Fully interchangeable with CSA/ATEX/IECEx hazardous area certifications.
  • ClickLoc connectors, 330N pull strength, and API 670 compliance.
The 86691-00680-0350-90-05 is engineered for reliable vibration and position measurement on fluid-film bearing machines. Its 8mm probe design provides thicker encapsulation of the probe coil in molded PPS plastic, resulting in a more rugged probe compared to 5mm alternatives. The armored construction with 3/8-24 UNF threads ensures durability in demanding industrial environments. The 86691-00680-0350-90-05 delivers high-performance eddy current measurement with complete API 670 compliance for mechanical configuration and accuracy.

The 86691-00680-0350-90-05 supports complete interchangeability with both XL and non-XL 3300 series 5mm and 8mm components, eliminating the need to match or bench calibrate individual components. With CSA, ATEX, and IECEx approvals, the 86691-00680-0350-90-05 is suitable for hazardous area installations. The 5.0-meter total cable length is designed for use with 5-meter Proximitor sensors, ensuring system compatibility.

The 86691-00680-0350-90-05 incorporates patented TiLoc molding for a robust bond between the probe tip and body, and CableLoc design providing 330 N (75 lbf) pull strength. Gold-plated ClickLoc connectors require only finger-tight torque and feature a locking mechanism to prevent loosening. The 86691-00680-0350-90-05 includes connector protectors for enhanced environmental protection, ensuring reliable performance in harsh industrial conditions.

The 86691-00680-0350-90-05 Bently Nevada Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer GE / Bently Nevada
  • Model 86691-00680-0350-90-05
  • Condition New Original ready stock
  • Product Family 330101-00-12-10-02-05,330101-00-16-10-02-00,330101-00-50-10-02-00
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.
  • Touch-Safe Personnel Protection: Achieves an official IP20 degree of protection, meaning it blocks fingers or tools larger than 12.5 mm from touching bare internal bus traces, protecting operators during diagnostic checkups.
  • Centrifugal Compressors: Embedded within heavy-duty oil refinery and petrochemical transport gas compressors to map radial dynamic movement.
  • Large-Scale Generators & Motors: Tracks structural thrust displacement and thermal axial expansion inside heavy utility industrial drive units.
  • Gearboxes & Hydro Turbines: Monitors internal shaft alignment and bearing wear states under extreme process conditions.
  • No Internal Firmware: The device operates completely on physical analog electromagnetic principles (generating eddy currents via an RF signal generated by an external Proximitor). There is no firmware to maintain, corrupt, or update on the probe itself.
  • External Rack/Transmitter Firmware: Any digital data translation or diagnostic firmware updates are handled strictly at the machine protection monitor level, such as upgrading the firmware on Bently Nevada 3500/40M or 3701 Proximitor Monitor modules via the Bently Nevada 3500 Rack Configuration Software or Orbit Studio.
  • Hardware Revisions: Physical product revisions are tracked by Bently Nevada via internal manufacturing date codes stamped on the tag. The underlying electrical calibration remains retro-compatible with all standard 3300 XL series matching electronics.
  • Hardware Matching Loop (The 9-Meter Configuration): The model string containing 90 indicates it is calibrated for a 9.0-Meter Total System Length. To function correctly, it must be paired exclusively with a 3300 XL 8mm Proximitor configured for a 9m setup, alongside a matching 3300 XL extension cable. Mis-matching components (e.g., using a 5m extension cable) will skew the circuit's impedance and ruin the sensor's accuracy.
  • Target Material Calibration: The system comes factory-calibrated to a standard AISI 4140 steel target block [3300 XL 8mm - Baker Hughes]. If your machine shaft uses a non-standard alloy (such as stainless steel or Inconel), the system will require manual scale-factor adjustments or custom calibration curves mapped in the monitoring rack configuration.
  • Physical Gap Configuration (Voltage Tuning): During machine standstill installation, the probe is mechanically threaded into place until its physical gap voltage reads approximately –10.0 VDC (the precise linear midpoint of the sensor's 80-mil dynamic operating span) measured across the Proximitor's terminal blocks using a digital multimeter.
Description
The 86691-00680-0350-90-05 is a high-performance 3300 XL 8 mm proximity probe designed for vibration and position measurement on fluid-film bearing machines. This probe provides an output voltage directly proportional to the distance between the probe tip and the conductive target surface. The 86691-00680-0350-90-05 is ideal for turbines, compressors, and other rotating machinery requiring precise monitoring.

The 86691-00680-0350-90-05 features a 6.80-inch overall case length and a 3.50-inch unthreaded length with 3/8-24 UNF threads and armored cable construction.
