Industry Applications
The 330709-000-030-10-02-00 excels in monitoring radial vibration and axial position of rotating shafts in steam turbines, compressors, and pumps. Its 11 mm sensing face and 1.0 m cable length suit installations in confined spaces. With a 30.5 mm minimum target diameter, it is ideal for small-to-medium shaft diameters. The probe's 177°C rating allows use near hot bearings, while the ClickLoc connector ensures secure signal transmission even under vibration.
Installation & Setup Guidance
Proper mounting is critical. Tighten the probe case to 63.3 N•m (M16x1.5 thread) to avoid air gaps. Use finger-tight torque for the connector (max 0.565 N•m). Ensure the minimum bend radius of 25.4 mm for the cable to prevent internal conductor damage. Verify the thread engagement does not exceed 24 mm to avoid case deformation. Avoid exposing the probe below -34°C during installation to preserve the pressure seal.
Maintenance & Reliability
Routine inspection should focus on cable condition, connector tightness, and probe tip wear. The PPS tip resists abrasion but may require replacement if damaged. The stainless steel case withstands corrosive environments. Periodic recalibration checks (every 12 months) ensure drift-free readings. Operating within the -52°C to +177°C range maximizes sensor life. Adhering to the cross-talk limitations (30.5 mm target, 152 mm shaft) prevents false proximity signals.
Selection Guide & Purchasing Advice
Before ordering the 330709-000-030-10-02-00, verify your mounting thread (M16x1.5), required cable length (1.0 m in this variant), and connector style (ClickLoc). This model does not include agency approvals (option 00). For matched systems, pair with compatible Bently Nevada monitors.
