Industry Applications

Vibration Monitoring in Turbomachinery

In steam turbines and gas turbines, the 330104-00-23-10-02-00 provides non-contact shaft displacement measurement. Its 8 mm diameter and 1.0 m cable length suit tight bearing housing installations. The PPS tip withstands oil mist and high temperatures common in turbine environments.

Compressor Protection

Centrifugal and axial compressors require precise rotor position monitoring to prevent rubs and surge events. This Bently Nevada probe delivers the accuracy needed for predictive maintenance programs, helping reduce unplanned downtime.

Installation & Setup Guidance

Mount the probe using the M10 x 1 threaded body. Ensure the unthreaded length (00 mm) allows the tip to extend fully into the measurement zone. Use the miniature coaxial ClickLoc connector for quick, secure cable attachment. Gap the probe at 1.27 mm (50 mils) to an AISI 4140 steel target for optimal linear range. Verify the system uses only 3300 XL 8 mm components for specified accuracy.

Maintenance & Reliability

Inspect the Viton O-ring seal periodically for signs of wear or leakage. Check the PPS tip for scratches or contamination that could affect measurement accuracy. The stainless steel case resists corrosion in most industrial environments. For maximum reliability, follow the manufacturer's guidelines for periodic verification of probe resistance and system calibration.

Compatibility & Integration

This probe works exclusively with 3300 XL 8 mm Proximitor Sensors and extension cables. It accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm probe. Power requirement: -17.5 Vdc to -26 Vdc (non-incendive) or -23 Vdc to -26 Vdc with barriers, at 12 mA maximum consumption. Output resistance is 50 Ω. For best performance, use the specified AISI 4140 steel target.
