Description
330904-02-10-70-01-00 is a 3300 XL NSv proximity probe configured with an M8 x 1 thread (330904), 0.2 inch unthreaded length (Option 02), 1.0 inch case length (Option 10), 7.0 meter total system length (Option 70), and includes a miniature coaxial ClickLoc connector with connector protector and standard cable (Option 01). This probe is designed for use in the 3300 XL NSv Proximity Transducer System, specifically for monitoring machinery where tight installation constraints or small target geometries limit the use of standard 5 mm or 8 mm systems.
The 3300 XL NSv system is ideal for small-bore applications, aeroderivative turbines, and high-speed equipment. It provides precise measurements for radial vibration, radial position, axial (thrust) position, tachometer, and Keyphasor signals. By utilizing the 330904 model, users gain the mechanical protection of integrated stainless steel armor, which helps ensure durability in demanding industrial environments.
Features
- M8 x 1 thread with stainless steel armor for improved mechanical durability
- 1.0 inch case length and 0.2 inch unthreaded length configuration
- 7.0 meter total system length for flexible installation distance
- Miniature coaxial ClickLoc connector with connector protector and standard cable
- Compatible with 3300 XL NSv Proximitor Sensor and 3300 NSv extension cables
- Designed for tight installation requirements, small shaft measurements, and reduced side-view applications
Applications
- Centrifugal air and process gas compressors
- Aeroderivative turbines and high-speed rotating equipment
- Shaft radial vibration and position measurement for shafts smaller than 51 mm
- Axial (thrust) position measurement for flat targets smaller than 15 mm
- Tachometer and zero speed sensing
- Phase reference (Keyphasor) applications

Installation Guidelines
Ensure the probe is installed with the correct gap setting, typically 1.0 mm (40 mils), to maintain linear performance. When routing cabling, observe the bending radius limits of the 75 ohm coaxial cable to prevent signal degradation. If installed in a hazardous area, ensure the setup complies with the applicable Bently Nevada installation drawings for the selected approval level. Use connector protectors to seal connections in environments where moisture or contamination is a risk.
