- CN Connector: Bayonet-lock CN connector ensures secure, vibration-resistant field termination
System Architecture & Signal Flow
The 330901-00-40-10-02-CN operates as the sensing element within a three-component Bently Nevada proximity system:
- Proximity Probe (330901-00-40-10-02-CN) — Generates eddy-current field; outputs raw impedance change as voltage shift via integral cable to driver.
- Extension Cable (3300 XL NSv compatible) — Transmits signal from probe to driver/oscillator; length must be matched to system calibration.
- Driver / Oscillator (3300 XL NSv series) — Conditions signal, provides –24 VDC excitation, outputs calibrated –1 V to –19 V proportional to gap distance to monitor card.
- Monitor Card (3300 XL NSv) — Processes driver output for vibration amplitude, phase, and DC gap; triggers alarms and trips per API 670 setpoints.
Note: Total system cable length (probe + extension) must match the driver calibration. Consult Bently Nevada system documentation (D/N 141536-01) for cable length combinations.

Technical FAQ
Q: Is this probe compatible with the standard 3300 series (non-XL NSv) drivers?
A: No. The 3300 XL NSv probe is calibrated for NSv-architecture drivers. Use with standard 3300 drivers will result in incorrect scale factor output. Verify your driver part number before ordering.
Q: Can this probe be used with non-AISI 4140 target materials?
A: Yes, with a correction factor. Bently Nevada publishes target material correction factors for common alloys (stainless steel, titanium, etc.). Contact us for the applicable factor for your application.
Q: What is the maximum allowable cable length for this probe?
A: The integral cable is 1.0 m. Total system length (probe + extension) is determined by the driver calibration — typically 5 m, 9 m, or 15 m total. Consult your driver documentation.
Q: Do you provide calibration certificates?
A: Functional verification data is available. NIST-traceable calibration certificates can be arranged for an additional fee — contact support@konmask.com.
Q: What is the lead time for out-of-stock units?
A: Typical sourcing lead time is 2–4 weeks for confirmed OEM-channel procurement. Contact us for urgent requirements.
