System Architecture & Signal Flow
The 330910-00-23-50-02-00 operates as part of a three-component eddy-current system:
- Proximity Probe (330910 series): Generates a high-frequency electromagnetic field; detects gap change to rotating shaft.
- Extension Cable: Transmits the RF signal from probe tip to driver with controlled impedance (matched to system).
- Proximitor® Driver / Signal Conditioner: Demodulates the RF signal and outputs a DC voltage proportional to gap distance (–24 VDC powered, 0 to –18 VDC output range).
Output signal feeds directly into Bently Nevada 3300 XL monitor input cards for display, alarming, and trip logic within a DCS or standalone machinery protection panel.

Technical FAQ
Q: Is 330910-00-23-50-02-00 compatible with the Bently Nevada 3500 monitor system?
A: Yes. The 3300 XL NSv transducer system is electrically compatible with 3500 series monitor input cards when used with the appropriate driver. Confirm driver part number with your system integrator.
Q: What is the difference between the -02-00 and -00-00 suffix?
A: The connector suffix (-02-00) specifies the 2-pin MIL-C-5015 connector configuration. The -00-00 suffix denotes a bare-wire termination. Ensure your installation matches the connector type.
Q: Can this transducer measure axial position as well as radial vibration?
A: Yes. With appropriate mounting orientation and monitor card configuration, the 3300 XL NSv system supports radial vibration, axial position (thrust), and differential expansion measurements.
Q: What target material is required?
A: The probe is calibrated for AISI 4140 steel. For other target materials (stainless steel, titanium, Inconel), a material correction factor must be applied. Contact Konmask technical support for recalibration guidance.
