Description

The 330905-08-13-10-02-05 is a 3300 XL NSv proximity probe featuring an M10x1 thread and an unarmored construction. This specific configuration includes an 80 mm unthreaded length (Option 08), a 130 mm case length (Option 13), and a 1.0-meter system length (Option 10). The probe utilizes a standard miniature coaxial ClickLoc connector (Option 02) and is certified with multiple hazardous area approvals (Option 05). The 3300 XL NSv Proximity Transducer System is engineered for machinery where space constraints limit the application of standard transducer systems. It is primarily used for radial vibration, axial position, tachometer, and Keyphasor measurements on fluid-filmed bearing machines. This probe is part of the NSv system, which requires compatibility with the 330980 Proximitor Sensor and 330930 extension cables to function as a complete measurement chain. It is optimized for applications with small target geometries, such as shafts smaller than 51 mm or targets smaller than 15 mm, providing superior side-view characteristics compared to legacy systems.

Installation Guidelines

• The NSv probe must be installed with a matching NSv Proximitor sensor and extension cable; components are not interchangeable with standard 3300 XL (non-NSv) hardware.
• Ensure the Proximitor sensor is mounted in a location providing at least IP54 protection in hazardous area applications.
• Use the recommended connector protectors on probe-to-extension cable and cable-to-Proximitor connections to prevent liquid ingress.
• Maintain the specified probe gap per the calibration curve provided with the Proximitor sensor.
• Follow Bently Nevada drawing 141092 for intrinsically safe (ia) installations and 140979 for non-incendive (nA/ec) installations.
