Technical Dossier
The 3300 XL Series succeeded the original Bently Nevada 3300 Series, introducing extended temperature range operation, improved EMI immunity, and tighter linearity tolerances. Early 3300 probes operated with a standard gap range of 0.25–2.25 mm and were calibrated against AISI 4140 steel targets. The XL revision extended the linear range and introduced the 8 mm and 11 mm probe diameters as the dominant field standards, replacing the earlier 5 mm and 14 mm variants in most new installations.
The 3300 XL proximitor sensors introduced a standardized -24 VDC supply rail and a -18 VDC nominal output at mid-gap, enabling direct interface with Bently Nevada 3500 Series rack-based monitoring systems and third-party DCS platforms via 4–20 mA converters. The series also introduced the NSv (Non-Standard voltage) calibration option for stainless steel and titanium target materials, critical for aerospace and marine applications. As the 3300 XL has entered its mature lifecycle phase, DriveKNMS maintains a dedicated inventory of both active and discontinued variants to support long-term plant maintenance contracts and turnaround schedules.
The following SKUs represent the verified 3300 XL Series module range, classified by probe diameter, cable length, and connector configuration. All models are calibrated for AISI 4140 steel targets unless otherwise noted.
8mm Proximity Probes — Standard Series
11mm Proximity Probes — Standard Series

For plants operating under long-term service agreements or API 670 compliance mandates, DriveKNMS provides multi-year supply contracts covering the full 3300 XL probe-cable-proximitor assembly chain. Discontinued variants including the 330104-00-06-05-02-CN and associated NSv-calibrated proximitors are held in controlled storage and available for immediate dispatch. Customers requiring cross-reference to 3500 Series or Velomitor replacements can request a compatibility assessment.
Each 3300 XL unit processed by DriveKNMS undergoes a structured verification protocol specific to eddy-current transducer systems. Gap voltage linearity is measured across the full manufacturer-specified linear range using a calibrated AISI 4140 steel target plate on a precision micrometer stage. Output voltage at nominal gap (-18 VDC ±0.5 VDC) is verified against the original Bently Nevada calibration certificate where available.
Extension cable continuity, shield integrity, and connector pin resistance are tested to IEC 60068 environmental stress standards. Proximitor sensors are bench-tested under -24 VDC supply with matched probe and cable assemblies to confirm system-level frequency response within the 10 kHz bandwidth specification. Units exhibiting gap voltage deviation exceeding ±2% of the published calibration curve are rejected. All tested assemblies are issued a DriveKNMS inspection report and shipped with original or equivalent connector protection caps.
