Features:
- 120 mm case with 40 mm unthreaded section reaches deep into machinery while adapting to varying wall thickness without custom threads.
- Armor protection guards the probe against crushing and abrasion during conduit pulls and rough field handling.
- CSA, ATEX, and IECEx approvals enable use in hazardous areas across North America, Europe, and international sites.
The 330104-04-12-05-01-05 is built for installations where the probe has to reach past thick casings or insulation. Its 120 mm case provides the length to get to the target, while the 40 mm unthreaded section lets you accommodate different wall thicknesses without waiting for custom-thread probes or stacking spacers.
Field crews appreciate the armor on the 330104-04-12-05-01-05 when they’re pulling cable through restrictive conduit or working around sharp edges. The protective layer absorbs the scrapes and impacts that would otherwise nick or crush standard cable jackets, keeping the internal wiring intact. For maintenance teams that have replaced probes damaged during installation, this added durability translates to fewer callbacks and less rework.
With CSA, ATEX, and IECEx marks, the 330104-04-12-05-01-05 covers the hazardous area requirements for most industrial regions. A refinery in Texas, a chemical plant in Germany, or an offshore platform in the North Sea can use the same part number. This simplifies procurement for multinational projects and keeps spare parts inventory lean.
The 330104-04-12-05-01-05 Bently Nevada 3300 XL 8 mm Proximity Probes may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Reverse Mounting: This model is specifically designed for reverse mounting. Technicians can screw the probe in from outside the machine housing and adjust its clearance to the shaft without disassembling the expensive and heavy machine cover [1, 5].
- Radial Vibration and Axial Displacement: Primarily monitors shaft vibration (displacement) and pusher position in steam turbines, gas turbines, centrifugal compressors, and large pumps [1, 2].
- Speed and Keyphasor: Mounted in a groove or protrusion on the shaft, it provides a pulse signal per revolution for calculating speed and performing phase analysis [1].
- OK Circuit Diagnosis: When used with the 3500 monitoring system, the system continuously monitors circuit integrity. If the cable breaks or the connector becomes loose, the system will immediately trigger a "Not OK" state and suppress false trips, preventing unnecessary downtime due to sensor malfunction.
- Gap Voltage Monitoring: By measuring the static output voltage of the preamplifier (usually adjusted to around -10.0V DC), it is possible to visually diagnose whether the probe has become physically loose, excessively worn, or has an abnormal shaft position deviation.
- Performance Improvement: The 3300 XL probe can directly replace the older 3300 series 8mm probe. It is recommended to replace the 3300 XL preamplifier simultaneously after the upgrade for more stable linearity (7.87 V/mm) and better electromagnetic interference immunity.
- Certification Compliance (-05): Possesses multiple international explosion-proof certifications (such as ATEX/IECEx/NEPSI), ensuring safe operation in hazardous areas such as Zone 0 or Class I, Div 1.
