Features:
- 8 Mm Eddy Current Probe Delivers High-Precision Shaft Displacement And Vibration Measurement.
- Viton® O-Ring And Stainless Steel Case Provide Reliable Sealing And Long-Term Durability.
- ClickLoc Connector With FluidLoc Cable Ensures Stable Signal Transmission Up To 5 Meters.
The Bently Nevada 330103-00-22-50-12-RU 3300 XL 8 mm Probe is engineered for accurate, non-contact monitoring of rotating machinery. It enables detection of subtle shaft movements and vibration patterns, supporting continuous protection of critical equipment in turbines, compressors, and generators.
Designed for robust industrial performance, the probe incorporates a stainless steel case with a Viton® O-ring seal to maintain differential pressure integrity. It operates across a wide frequency range up to 10 kHz and features a nominal DC resistance of 8.73 ± 0.50 Ω, delivering consistent signal quality even with extended field wiring.
The probe integrates seamlessly with the 3300 XL system, including extension cables and Proximitor sensors, to form a complete transducer solution. Its flexible overall length and compact design allow for installation in tight spaces, while the system provides comprehensive monitoring data for vibration, shaft position, and Keyphasor reference signals, supporting predictive maintenance and early fault detection.
The 330103-00-22-50-12-RU Bently Nevada 3300 XL 8 mm Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Gap Voltage Measurement: Measure the DC voltage at the preamplifier output using a multimeter. The standard operating point is typically -9.0 VDC (corresponding to approximately a 1.27 mm gap).
- Linearity Check: Move the probe using a static calibrator (e.g., TK-3) to confirm that the voltage change conforms to a sensitivity of 7.87 V/mm (200 mV/mil).
- Connector Integrity: Check the ClickLoc connector for moisture or contamination, which can cause signal jumps or high-frequency noise (spikes).
- Insulation Resistance Test: Measure the insulation between the probe's center wire and the housing. Low resistance indicates potential wear at the probe tip or internal oil ingress.
- Gapping: Adjust the distance between the probe and the shaft by mechanically rotating the probe, observe the preamplifier voltage output, and set it to the midpoint of the range (usually around -10V).
- Thread Tightening Torque: As an M10 x 1 specification threaded probe, a lock nut must be used during installation, and the torque recommended in the manual must be strictly followed to prevent damage to the housing threads.
- Cable Wiring Protection: Since this model is unarmored, the cable must be run through a conduit or secured with cable ties to prevent wear due to vibration.
- Minimum Cable Bending Radius: The bending radius of the coaxial cable should not be less than 25.4 mm (1 in), otherwise the internal shielding layer will be damaged, affecting signal accuracy.
- Deep Hole Installation Environments: The extra-long 220mm (22) housing design is specifically designed for turbine installations requiring passage through heavy bearing housings or deep lubrication holes.
- Radial Vibration Measurement: Paired (X-Y axis) mounting on sliding bearings to capture the shaft's orbit.
- Axial Displacement Monitoring: Mounted at the thrust bearing to monitor axial movement of the rotor relative to the stator, preventing pusher pad burnout.
- Leak-Proof Industrial Scenarios: Utilizing FluidLoc (12) liquid-resistant cables to prevent lubricating oil from seeping into the bearing housing along the cable core, keeping the junction box dry.
