The 330901-05-55-05-11-05 is a 3300 NSv narrow gap series non-contact eddy current proximity probe. This model is developed for narrow and compact spaces inside industrial machinery, and is widely used for axial displacement and shaft vibration measurements in various process compressors, gearboxes, and pumps.
Excellent Chemical Resistance
High-strength one-piece molding process
Vibration-resistant self-locking connector
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).
The 3300 XL NSv Transducer System design allows it to replace both the 3300 RAM Transducer Systems and the 3000-series or 7000-series 190 Transducer System. Upgrades from the 3300 RAM system to the 3300 XL NSv system may use the existing probe, extension cable, and monitoring system with 3300 XL NSv Proximitor Sensor. Upgrades from the 3000-series or 7000-series Transducer System must replace the probe, extension cable, and Proximitor Sensor with NSv components.
The 3300 XL NSv Transducer System has an Average Scale Factor of 7.87 V/mm (200 mV/mil), which is the most common output for eddy current transducers. Its enhanced side view and small target characteristics give it a shorter linear range than the Bently Nevada 3300 XL-series 5 and 8 mm Transducer System. The 1.5 mm (60 mils) of linear range exceeds the linear range of the 3000-series 190 Transducer System.

Oil & Gas Refining
Monitors shaft vibration of large centrifugal compressors in catalytic cracking units to prevent impeller-to-casing rub.
Thermal Power Generation
Measures shaft displacement and bearing wear in small steam turbines and feedwater pumps to ensure continuous generator operation.
Petrochemical Industry
Monitors axial displacement of critical process pumps in ethylene cracking plants to prevent high-pressure fluid leakage.
Metallurgy & Iron/Steel
Monitors the vibration status of blast furnace blowers and high-speed shafts in steel rolling mill gearboxes to avoid unplanned downtime.
Paper & Pulp Industry
Monitors shaft vibration of paper machine drying cylinders and high-speed press roll bearings to ensure uniform paper thickness.
Cement Manufacturing
Monitors mechanical vibration of bearings in large exhaust fans and rotary kiln drive gearboxes.
When using the 330901-05-55-05-11-05 probe, strictly control the electrical installation gap via the casing thread, do not exceed the maximum tightening torque of 7.3 N·m, and avoid any impacts on the case. The probe must be used with a 3300 XL NSv Proximitor and the correct extension cable to match the total system length (5.0m or 7.0m); never cut the 0.5m integral cable, and avoid tight bending radii during wiring.
Securely lock the ClickLoc connector protector to prevent oil or water ingress, maintain the operating temperature between -34°C and +177°C, and regularly check the DC resistance between the center conductor and outer shield (approx. 4.0 ± 0.5 Ω).
The 330901-05-55-05-11-05 model is a 3300 NSv proximity probe that is mechanically and electrically compatible and interchangeable with the 3300 RAM system. It offers enhanced chemical resistance and features a stainless steel case with 1/4-28 UNF threads. The unit utilizes TipLoc and CableLoc technologies to ensure high-strength connections and is equipped with self-locking, gold-plated brass ClickLoc connectors.
This is a non-contact eddy current proximity probe from the 3300 XL NSv series, designed to measure shaft vibration and displacement in rotating machinery.
How to correctly install 330901-05-55-05-11-05?
Thread the probe into the mounting hole via its 1/4-28 UNF casing thread, adjust the initial electrical gap between the probe tip and the target shaft surface, and then lock it with a nut.
What are the core technical advantages of 330901-05-55-05-11-05?
Compared to standard probes, it has enhanced side-view characteristics, making it suitable for restricted areas like counterbores and for measuring small shafts under 51 mm (2 inches).
