Why Engineers Specify This Model
- NSv Architecture – Non-Standard Voltage output eliminates ground-loop interference in long cable runs common in large plant installations.
- 3300 XL Platform Compatibility – Drop-in replacement for legacy 3300 series installations; backward-compatible with existing 3300/05 and 3300/16 monitors.
- Extended Temperature Probe – Rated to 177 °C, suitable for hot-section turbine bearing pedestals without additional cooling.
- API 670 Compliant – Meets the 5th Edition standard for machinery protection systems, satisfying insurance and regulatory requirements.
- Plug-and-Play Integration – Pre-matched probe/extension/driver set eliminates field calibration; system ships as a calibrated assembly.
- Hazardous-Area Rated – ATEX/IECEx certification allows direct installation in Zone 1 and Zone 2 classified areas.

Application-Specific FAQ
Q: Is the 330904-00-12-50-02-00 compatible with the Bently Nevada 3500 rack?
A: Yes. The NSv Proximitor output is compatible with 3500/42 and 3500/45 monitor modules when configured for the correct input range. Verify the monitor’s input card revision before installation.
Q: Can this transducer measure axial position as well as radial vibration?
A: Yes. The 3300 XL NSv system measures both dynamic (vibration) and static (DC gap / axial position) displacement. Axial thrust position monitoring requires a dedicated axial probe mounting arrangement per API 670 §6.
Q: What is the difference between the standard 3300 XL and the NSv variant?
A: The NSv (Non-Standard Voltage) variant uses a different Proximitor supply voltage configuration to reduce common-mode noise in installations with long cable runs or shared power supplies. It is not interchangeable with standard 3300 XL drivers without reconfiguration.
Q: Do you supply calibration certificates?
A: Factory calibration data is available for units with traceable serial numbers. Third-party calibration certificates can be arranged on request at additional cost.
Q: Can I use this probe on non-ferrous targets such as aluminum impellers?
A: The standard calibration is for AISI 4140 steel. Non-ferrous or non-standard target materials require a target material correction factor or a custom calibration. Contact us for guidance.
