- Extended Temperature Range: Suitable for both cryogenic and high-temperature process environments.
System Architecture & Signal Flow
The 330902-00-40-10-02-CN operates as a three-component eddy-current measurement chain:
- Probe (330902): Generates a high-frequency electromagnetic field. Eddy currents induced in the rotating target shaft attenuate the field proportionally to gap distance.
- Extension Cable: Transmits the oscillator signal between probe and Proximitor with controlled impedance to preserve measurement accuracy over distance.
- Proximitor® Sensor: Demodulates the oscillator signal and outputs a DC voltage linearly proportional to probe-to-target gap. Output feeds directly to the 3500 monitor rack or DCS analog input.

Technical FAQ
Q: Is the 330902-00-40-10-02-CN compatible with the Bently Nevada 3500/42M monitor?
A: Yes. The NSv output is directly compatible with the 3500/42M Proximitor/Seismic Monitor configured for 3300 XL NSv transducers.
Q: What is the difference between the -CN and standard connector versions?
A: The -CN suffix denotes a China-regional connector configuration. Electrically and mechanically identical to the standard version; only the field connector differs.
Q: Can this transducer be used on non-ferrous targets?
A: The standard calibration is optimized for AISI 4140 steel. For non-ferrous or exotic alloy targets, a target-specific calibration factor must be applied — contact our engineering team for guidance.
Q: Do you provide calibration certificates?
A: Factory calibration data is available for new units. For recertification services, we can coordinate with accredited metrology labs.
