Description

The Bently Nevada 330710-000-060-50-02-00 is a 3300 XL 11mm Proximity Probe designed for high-performance vibration and position monitoring in rotating machinery. As a core component of the 3300 XL 11mm Proximity Transducer System, this probe provides a 3.94 V/mm (100 mV/mil) output for non-contacting measurements. The larger 11mm tip diameter offers an extended linear range compared to standard 8mm systems, making it suitable for applications where greater clearance or thermal growth is expected.

Features

• M16 x 1.5 metric thread with armored construction for harsh industrial environments
• Extended linear range enabled by 11mm probe tip
• Patented TipLoc molding for a robust probe tip bond
• Patented CableLoc design providing 330N (75 lbf) pull strength
• Includes 5.0-meter cable with miniature coaxial ClickLoc connector
• Viton O-ring seal for differential pressure protection

Applications

• Axial (thrust) position measurements
• Ramp differential expansion measurements on steam turbines
• Rod position or rod drop measurements on reciprocating compressors
• Tachometer and zero speed measurements
• Phase reference (Keyphasor) signals

Installation Guidelines

• Ensure the target shaft surface is clean, smooth, and free of scratches to prevent false readings.
• Maintain proper side clearance around the 11mm probe head to avoid side-wall interference.
• Thread the probe by hand into the mounting bracket; do not use tools to torque the probe against the shaft.
• Set the physical gap according to the system requirements (typically centered around 2.0 to 3.0 mm).
• Secure the locknut against the housing; ensure the cable is not twisted during the tightening process.
• This probe must be used exclusively with compatible 3300 XL 11mm extension cables and 11mm Proximitor sensors.

FAQ

What is the 330710-000-060-50-02-00?

The 330710-000-060-50-02-00 is a specific variant of the 3300 XL 11 mm Proximity Probe, primarily used for continuous shaft displacement, rotor speed, and vibration monitoring in large-frame rotating machinery.

Why use an 11 mm probe instead of a standard 8 mm probe?

The larger 11 mm tip allows for a longer linear measurement range. This is ideal for large-frame rotating machinery where shaft clearances and thermal growth patterns exceed the limits of standard 8 mm probes.

Can I mix this probe with 8 mm or 50 mm components?

No. You must connect this 11 mm probe exclusively to a 3300 XL 11 mm extension cable and an 11 mm Proximitor sensor. Mixing sizes will lead to calibration errors and incorrect data.
