Product Details
The 330851-02-000-050-10-00-05 is a 25 mm eddy-current proximity probe manufactured by Bently Nevada as part of the 3300 XL transducer system. It is designed for large rotating machinery to monitor differential expansion, radial vibration, and shaft position in high-temperature environments. This specific configuration features an M30 x 2 thread, an unarmored housing, a 50 mm overall case length, and a 1.0-meter integral cable.
The part number nomenclature encodes specific mechanical and electrical construction options. The 330851-02 base designation identifies the 25 mm probe platform, while the 000 unthreaded length and 050 case length options define the physical dimensions behind the polyetheretherketone tip. The 10 option designates the 1.0 m cable length, option 00 specifies unarmored cable construction, and the 05 suffix indicates multiple agency approvals.

Operating as an eddy-current transducer, the probe utilizes a PEEK tip and stainless-steel case to maintain structural and electrical stability under elevated thermal conditions up to 200 deg C continuously, with short-term tolerance up to 250 deg C. Its unarmored 1.0 m integral cable requires proper mechanical routing and protection against physical abrasion in industrial installations.
Field Installation and Maintenance
Proper installation requires maintaining clean M30 mounting threads and ensuring appropriate torque during mechanical seating to prevent loosening under heavy machinery vibration. Route the 1.0 m integral coaxial cable away from high-current power conductors to minimize electromagnetic interference, and verify that all coaxial connections are fully engaged prior to system startup.
Frequently Asked Questions
Q: Does this 25 mm probe require an extension cable?
A: Yes, the 1.0 m integral cable requires a compatible 3300 XL 25 mm extension cable to reach the Proximitor monitor and satisfy total system length requirements.
Q: What is the maximum short-term temperature rating for this probe?
A: It withstands temperatures up to 250 deg C for durations of less than 24 hours, with a continuous operating range of -35 deg C to 200 deg C.
