3300 XL NSv Proximitor Sensor
The 3300 XL NSv Proximity Transducer system is intended for use with centrifugal air compressors, refrigeration compressors, process gas compressors, and other machines with tight installation requirements. 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 51 mm (2 in) or axial position on flat targets smaller than 15 mm (0.6 in). It is primarily used in the following applications on fluid-filmed bearing machines

Industrial Refrigeration
Connects NSv probes inside centrifugal refrigeration compressors. Uses FluidLoc technology to prevent refrigerant and oil wicking through the cable.
Petrochemical Industry
Used for seal gas booster pump monitoring. Its 05 certification ensures safe transmission of small rotor displacement data in hazardous gas environments.
Fine Chemicals
Transmits vibration signals from small-diameter shafts in high-speed centrifuges; the oil-proof cable resists chemical interference.
Rail Transit
Applied to small centrifugal units in train HVAC systems, connecting probes to Proximitors to monitor on-board power stability.
When using the 330906-02-12-10-12-05 extension cable, ensure that it is used in conjunction with the 3300 XL NSv dedicated probe and preamplifier. Do not mix it with standard 8mm components to prevent reading failure. During installation, ensure the total length of the probe + extension cable matches the preamplifier requirements, and do not cut or splice the cable to maintain impedance matching. Utilize its FluidLoc oil penetration resistance, and use heat shrink tubing for insulation and moisture sealing after connection. Pay attention to bending radius during wiring to avoid damaging the built-in stainless steel protective sleeve, and strictly use it in conjunction with intrinsically safe safety barriers in explosion-hazardous areas.
The 330906-02-12-10-12-05 is a 3300 XL NSv (Narrow Side View) series reverse mount eddy current proximity probe manufactured by Bently Nevada.
How to use products like the 330906-02-12-10-12-05?
This probe uses a reverse mount design and is typically threaded from the inside of the machine's bearing housing outward or using a reverse mount bracket. To use it, position the tip directly facing the metal shaft surface and adjust the depth to ensure the initial gap is within the linear region. Its connector must be attached to a 3300 XL NSv Proximitor via an extension cable to work properly.
What is the main advantage of the 330906-02-12-10-12-05 compared to standard 8 mm probes?
Its biggest advantage is that its side magnetic field is very narrow. When the probe must be installed in deep holes (counterbores) or environments with tight metal walls on the sides, it will not generate false measurement readings due to side-metal interference.
What should be paid attention to in the daily maintenance of the 330906-02-12-10-12-05?
The maintenance focus is on keeping the ClickLoc connector clean and never letting oil or dust contaminate its interior; additionally, sharp bends in the cable must be avoided, keeping the bend radius above 25.4 mm.
What is the standard linear measuring range and sensitivity of the 330906-02-12-10-12-05?
Its standard linear measuring range is 1.5 mm (60 mils), which is slightly smaller than the 2.0 mm of standard 8 mm probes. Its standard output sensitivity is 200 mV/mil (approx. 7.87 V/mm).
