System Architecture & Signal Flow
The 330180-12-BR operates as the sensing element within a three-component Bently Nevada transducer system:
- Probe (330180-12-BR): Generates an oscillating electromagnetic field; eddy currents induced in the target shaft modulate the field proportionally to gap distance.
- Extension Cable (330130-XX-CN): Transmits the modulated RF signal from probe to driver with minimal loss; total system cable length must match driver calibration.
- Proximitor® Driver (3300 XL NSv / 3500 series): Demodulates the RF signal and outputs a DC voltage proportional to gap (–24 VDC supply; 0 V to –18 V output range).
The DC output feeds directly into Bently Nevada 3500 Series monitor cards or any 4–20 mA / voltage-input DCS/PLC system via appropriate signal conditioning.

Technical FAQ
Q: Is the 330180-12-BR interchangeable with the 330180-12-CN?
A: The probe body and sensing performance are identical. The suffix denotes connector type: BR = Bayonet Reverse; CN = Cannon (MIL-spec). Verify your extension cable and driver connector before ordering.
Q: Can this probe measure non-ferrous targets (aluminum, titanium)?
A: Yes, but the scale factor will deviate from the nominal 7.87 V/mm. Bently Nevada provides target material correction tables; contact our engineering team for application-specific calibration guidance.
Q: What is the maximum shaft speed this sensor can monitor?
A: The 10 kHz frequency response supports shaft speeds up to approximately 600,000 RPM for once-per-revolution events, well beyond the range of any practical rotating machinery.
Q: Do you supply the matching extension cable and Proximitor® driver?
A: Yes. We stock the complete 3300 XL transducer system. Contact us with your total cable length requirement and driver model for a matched-system quotation.
Q: Is ATEX certification available?
A: ATEX/IECEx variants exist within the 330180 family. Confirm your hazardous area classification (Zone/Group/Temperature Class) and we will identify the correct certified part number.
