Applications
This Bently Nevada 330101-00-59-15-12-05 probe suits radial vibration monitoring on compressors, turbines, and pumps where a 2 mm linear range and -9 Vdc gap setting provide accurate displacement measurement. Its FluidLoc cable prevents oil leakage through the cable interior, making it suitable for oil-lubricated machines. The CSA, ATEX, and IECEx approvals allow use in hazardous areas. PLC Source PRO supplies genuine Bently Nevada parts with fast quote response and technical support.
Compatibility and Selection Guide
Use this probe with 3300 XL Proximitor sensors and extension cables to maintain system accuracy. The 1.5 meter total length and ClickLoc connector ensure a secure, reliable connection. For extended temperature applications, select the ETR probe variant rated to +218°C at the tip. When ordering, specify the unthreaded length, case length, total length, connector type, and approval options to match your machinery requirements.
Installation and Maintenance
Mount the probe using the 3/8-24 UNF thread and set the gap to -9 Vdc for radial vibration measurements. Use 3-conductor shielded triad cable for field wiring, with a maximum length of 305 meters (1,000 feet) between the Proximitor sensor and monitor. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The PPS tip and stainless steel case provide durability in industrial environments.
