330709-000-070-10-02-00 Bently Nevada 3300 XL 11 mm Probe
The Bently Nevada 330709 (Full Model: 330709-000-070-10-02-00) is a high-performance 3300 XL 11 mm eddy current proximity probe. Engineered for critical asset condition monitoring, this non-contact vibration probe delivers an extended 4 mm linear range. It serves as an essential machinery protection card input, making it a vital Bently Nevada spare part for heavy-duty industrial rotating machinery.
- Thrust Position Measurement: Operates as a reliable thrust displacement sensor for axial position monitoring to prevent catastrophic rotor-stator contact.
- Radial Vibration Monitoring: Specialized for fluid film bearing machines, including steam turbines, gas turbines, and centrifugal compressors.
- API 670 Compliant System: Acts as the primary interface for machinery protection systems and emergency shutdown systems (ESD).
This probe is fully compatible with the Bently Nevada 3500 rack module architecture. It operates as part of a complete 3300 XL transducer system, requiring connection to a matching 3300 XL Proximitor Sensor and an 11 mm extension cable to route high-accuracy signals to 3500/40M or 3500/42M monitors.

A1: The 330709-000-070-10-02-00 sits in the Bently Nevada 3300 XL 11 mm Probe line and is commonly seen in non-contacting vibration measurement jobs or axial position monitoring on rotating machinery.
Breaking the number down a bit — you get an M16x1.5 thread eddy current sensor, fully threaded body, 70 mm overall case length, and a built-in 1.0-meter triaxial cable. The connector style here is a miniature ClickLoc connector cable. No extra approval option is attached to this version. For many maintenance teams, this is simply a 3300 XL 11mm proximity probe replacement or one of those Bently Nevada spare parts kept on hand.
A2: Yes, usually it does. By itself, the probe will not make up a full 3300 XL transducer system.
A 5-meter system is often matched with a 4-meter extension cable (330730-040-XX-XX) and 330780-5X-XX Proximitor Sensor. If the system length goes to 9 meters, people normally switch to 330730-080-XX-XX plus 330780-9X-XX.
This kind of arrangement is pretty normal around a Bently Nevada 3500 rack module, 3500/40M monitor, or 3500/42M monitors.
A3: One thing installers usually pay attention to is the probe gap. Around 2.5 mm (100 mils) tends to be the normal setting for stable readings. Torque also matters. 21.1 N·m is the recommended value. Too tight is not a good idea here since thread damage can happen.
A4: The 330709-000-070-10-02-00 handles frequencies from 0 to 8 kHz and works in temperatures between -52°C and +177°C. So, whether it is steam turbines, gas turbines, fluid film bearing machines, or a centrifugal compressors monitor setup, this model turns up quite a lot in critical asset condition monitoring work.
