The Bently Nevada 3300 XL NSv Proximity Probe comes in varying probe case configurations, including armored and unarmored 1/4-28, 3/8 -24, M8 X 1 and M10 X 1 probe threads. The reverse mount 3300 NSv probe comes standard with either 3/8-24 or M10 X 1 threads. All components of the transducer system have gold plated brass ClickLoc connectors. The 3300 NSv probes are designed to seal differential pressure between the probe tip and case. The probe sealing material consists of a Viton O-ring.

The three parts of the system must have consistent electrical lengths. The electrical length of the proximity probe plus the electrical length of the extension cable must equal the electrical length of the Proximitor.

The primary uses for the 3300 XL NSv Transducer System are for areas where counter bore, sideview or rearview restrictions limit the use of standard Bently Nevada 3300 and 3300 XL 5 and 8 mm Transducer Systems. It is also ideal for small target applications, such as measuring radial vibration on shafts smaller than 51mm (2in) or axial position on flat targets smaller than 15mm (0.6in).
