The 330903-17-19-05-02-00 is a specific engineering configuration of the Bently Nevada 3300 NSv eddy current proximity sensor probe, designed for particularly compact spaces. This product belongs to the 3300 NSv proximity sensor system and is specifically designed to monitor small to medium-sized rotating machinery, small-diameter shaft equipment, or blind spots inside machinery where traditional 8mm probes cannot be inserted, using non-contact eddy current principles to achieve precise monitoring of shaft vibration, axial displacement, and rotational speed.
Axial (thrust) position measurements
Phase reference (Keyphasor signals)
Tachometer and zero speed measurements
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.

When using the 330903-17-19-05-02-00 narrow side-view probe, you must strictly ensure that the total electrical length of the system combined with this 0.5-meter probe (typically a 5-meter or 7-meter system) matches precisely to avoid severe measurement errors.
Since this model features an extremely long 170mm unthreaded length and lacks armored protection, special care must be taken during pass-through installation to prevent the non-threaded metal casing from bending or suffering severe scratches, while avoiding direct contact between the flexible cable and sharp mechanical edges.
Furthermore, although NSv technology provides excellent lateral immunity, the linear scale factor must still be re-verified in the field using a calibrator when dealing with extremely small targets under 9.5mm in diameter or when operating adjacent to large areas of irregular non-magnetic metals.
As a metric-level eddy current proximity probe built for highly confined spaces, the 330903-17-19-05-02-00 is a core component of the classic 3300 NSv monitoring system, featuring a 1.7-inch unthreaded length, a 1.9-inch stainless steel case (M8 x 1 thread specification), and a 0.5-meter standard unarmored coaxial cable. During system operation, the transducer utilizes a non-contact eddy current sensing mechanism to deliver an analog output voltage directly proportional to the gap distance between the probe tip and the observed conductive metal surface. It provides a nominal scale factor of 7.87 V/mm over its 1.5 mm (60 mils) linear range, enabling the real-time acquisition of both static displacement and dynamic shaft vibration values.
It is a 3300 NSv series eddy current proximity transducer probe manufactured by Bently Nevada, specially designed for non-contact displacement and vibration monitoring of industrial rotating machinery in confined spaces.
How do I use the 330903-17-19-05-02-00?
It is typically threaded into a machine bearing housing or internal mounting bracket with the probe tip facing the rotating shaft metal surface, and connected via its coaxial cable to an extension cable and a 3300 NSv Proximitor sensor.
What cable and connector configuration is selected for 330903-17-19-05-02-00?
For 330903-17-19-05-02-00, the configuration is a 0.5-meter standard coaxial cable without armor, terminating in a Miniature coaxial ClickLoc connector with a protector.
What temperature can 330903-17-19-05-02-00 withstand?
The operating temperature for both the probe and its attached cable is very wide, rated from -34 °C to +177 °C.
What is the initial gap voltage typically adjusted to during the installation of 330903-17-19-05-02-00?
For standard radial vibration monitoring applications, it is officially recommended to adjust the initial installation gap voltage to the linear midpoint within the range of -9 Vdc to -10 Vdc when the machine is at rest.
