Industry Applications
The Bently Nevada 330191-00-33-15-05 is ideal for upgrading legacy proximity probes in turbines, compressors, pumps, and other rotating equipment. Its 8 mm diameter provides a thicker encapsulation of the probe coil, offering superior resistance to physical abuse. The 1.5 meter total length (4.9 feet) suits common mounting configurations, and the 3/8-24 UNF thread ensures easy replacement. Use this probe in applications requiring reliable vibration monitoring with extended temperature capabilities.
Installation & Setup Guidance
When replacing an older probe with the 330191-00-33-15-05, ensure the unthreaded length (minimum 0.0 in) and overall case length (3.3 in) match your mounting requirements. The probe does not use an extension cable in a one-meter system; for the 1.5 m probe, confirm the cable path. Tighten connectors to 0.565 N·m maximum torque. The Viton® O-ring provides differential pressure sealing between probe tip and case – verify the O-ring is present before installation. Note: probes are not pressure tested prior to shipment.
Maintenance & Reliability
Patented features like TipLoc and CableLoc reduce common failure points, extending service life. The optional FluidLoc cable prevents oil leakage through the cable interior, minimizing maintenance. For best reliability, operate within the specified temperature schedule (e.g., T1: -55°C to +232°C for probe only). Regularly inspect the cable and connectors for damage; the gold-plated brass or beryllium copper connectors resist corrosion.
Selection Guide & Purchasing Advice
Verify your system requirements before ordering. The Bently Nevada 330191-00-33-15-05 includes a 12-month factory warranty from supplier PLC Source PRO. Ensure compatibility with your Bently Nevada monitor and extension cables. This model offers multiple agency approvals (option 05). For other cable lengths or armored options, consult the ordering guide. Choose this probe for an upgrade that delivers improved robustness and reliability.
