Industry Applications
Its robust TipLoc and CableLoc designs ensure reliable operation in harsh conditions. The FluidLoc cable option prevents oil leakage, making it suitable for lubricated machinery.
Installation & Setup Guidance
When installing the 330101-00-28-20-12-05, ensure the probe tip is properly gapped to -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration applications. Use the recommended torque values: 11.2 N•m (100 in•lbf) for standard forward-mounted probes and 7.5 N•m (66 in•lbf) for the first three threads. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and the monitor.
Maintenance & Reliability
The probe's PPS tip and stainless steel case (AISI 303 or 304 SST) provide durability. The patented TipLoc and CableLoc designs enhance mechanical integrity. Regularly inspect the probe and cable for physical damage. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.
Selection Guide & Purchasing Advice
When selecting a replacement probe, verify the thread size (3/8-24 UNF) and cable length (2.0 m) match your application. The 330101-00-28-20-12-05 is a standard probe without armor; for armored versions, consult Bently Nevada. AutoDCSTech stocks this exact model.
