        Features:

        • 170 mm unthreaded length with 190 mm overall case provides exceptional reach for deep-well installations through thick machine casings without standoffs.
        • M8 x 1 metric thread offers compact mounting compatibility while supporting the extended probe body required for deep reach.
        • Increased chemical resistance and superior side-view characteristics enable reliable operation in process compressor applications with accurate measurements in confined spaces.
        The 330903-17-19-05-02-00 is engineered for the most demanding deep-well applications where the measurement target sits far behind thick machine walls. Its 170 mm unthreaded section allows the probe to pass through heavy compressor casings, multiple insulation layers, or double-walled equipment without requiring standoffs or custom adapters. The 190 mm overall case length provides the structural integrity needed for such extended reach, ensuring the probe remains rigid and properly aligned even in high-vibration environments.

        Despite its exceptional length, the 330903-17-19-05-02-00 features an M8 x 1 metric thread—one of the most compact mounting options in the NSv series. This allows the probe to fit into standard metric ports without requiring adapters, even when the probe body is extended for deep reach. The thread is positioned at the mounting surface while the long unthreaded section extends into the machine, providing a secure anchor point without adding unnecessary bulk at the entry port. For facilities with metric equipment standards, this design eliminates the need for thread adapters that could introduce alignment issues.

        The 330903-17-19-05-02-00 offers significantly increased chemical resistance compared to previous 3300 RAM probe designs, making it ideally suited for process compressor applications where exposure to aggressive media is routine. The superior side-view characteristics of the NSv series compensate for installation limitations in confined spaces, enabling accurate measurements even when perfect perpendicular alignment is not possible.

        The 330903-17-19-05-02-00 Bently Nevada 3300 NSv Proximity Probes may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Small Centrifugal Equipment: Such as small compressors, expanders, and high-speed pumps, where bearing housing space is often very limited.
        • Narrow Borehole Monitoring: When the probe must be installed in a counterbore with a diameter less than 9.5 mm (0.375 in), the NSV probe prevents signal distortion caused by the borehole wall.
        • Small Diameter Shafts: Used for monitoring shafts with a diameter less than 76 mm (3 in), providing more accurate radial vibration and axial displacement data.
        • Dedicated Preamplifier Connection: Requires connection to the 3300 XL NSV preamplifier (Proximitor).
        • Signal Output: The preamplifier converts the gap change sensed by the probe into a standard voltage signal of -7.87 V/mm (-200 mV/mil).
        • System Integration: Typically connected to a Bently Nevada 3500 monitoring system or a 990/991 transmitter, and can be connected to System 1 software for dynamic spectrum analysis via the buffer output port.
        • API 670 Compliance: Its linearity, interchangeability, and environmental adaptability meet the American Petroleum Institute standards for mechanical protection systems.
        • Explosion Protection & Environmental Protection (00):Indicates No Approvals. This means that this particular model is typically used in non-hazardous areas or conventional industrial environments. For use in explosive gas environments (such as Zone 0/1), select the model with option 05.
        • OK Circuit Monitoring: The system automatically monitors the integrity of the probe circuit. In the event of a disconnection or short circuit, the system will trigger a "Not OK" state to prevent unplanned shutdowns due to false alarms.
        Description
        The 330903-17-19-05-02-00 features an M8 x 1 metric thread without armor, providing installation flexibility for applications requiring compact metric mounting with exceptional reach. This model includes a 0.5 meter (20 inch) total length with an unthreaded length of 170 mm and overall case length of 190 mm. 

        With a 170 mm unthreaded section, the 330903-17-19-05-02-00 is engineered for deep-well installations where the probe must reach far into the machine casing. The 190 mm overall case length provides the structural integrity needed for such extended reach, while the M8 x 1 thread fits compact metric ports. 

        The 330903-17-19-05-02-00 is mechanically and electrically compatible and interchangeable with Bently Nevada's previous 3300 RAM proximity probe designs. This NSv probe features increased chemical resistance compared to the 3300 RAM probe, allowing its use in many process compressor applications where exposure to aggressive media is common. 

        The side-view characteristics of the 330903-17-19-05-02-00 are superior to those of the 3000-series 190 probe when gapping at the same distance from the probe target. This improved performance enables more accurate measurements in confined spaces and applications where probe orientation presents challenges.

        Technical notes
        The 330903-17-19-05-02-00 is a 3300 XL 11mm Proximity Probe designed for differential expansion (DE) and thrust position measurements on large steam turbines and compressors.This probe offers a larger linear range (approximately 4 mm / 160 mils at 3.94 V/mm or 100 mV/mil sensitivity) compared to standard 8mm probes, making it suitable for applications with larger shaft movements.
