Engineering Advantages
- Non-contact measurement — Zero mechanical wear; suitable for continuous 24/7 operation
- High bandwidth (DC–10 kHz) — Captures sub-synchronous, synchronous, and super-synchronous vibration components
- Temperature-compensated electronics — Maintains calibration accuracy across the full operating temperature range
- API 670 compliant system — Meets international machinery protection standard when paired with 3300 NSv driver and monitor
- Plug-and-play 3300 NSv compatibility — Direct replacement for existing 3300 NSv installations; no recalibration of the driver required
- Robust coaxial connector — Resists vibration-induced loosening; IP67-rated cable assembly
System Architecture & Signal Flow
The 330903-00-09-10-01-CN operates as the sensing element in a three-component eddy current transducer system:
- Proximity Probe (330903-00-09-10-01-CN) — Generates the high-frequency electromagnetic field and senses target displacement.
- Extension Cable (3300 XL series) — Transmits the RF signal from the probe to the driver/oscillator with minimal loss.
- Driver / Oscillator (3300 NSv) — Conditions the signal and outputs a DC voltage proportional to the gap distance (–24 VDC supply required).
Note: The probe, extension cable, and driver must be purchased and calibrated as a matched set. Mixing components from different series will invalidate the scale factor and may trigger false alarms.

Technical FAQ
Q: Can I use this probe with a 3300 XL driver instead of the 3300 NSv driver?
A: No. The 3300 NSv probe is calibrated specifically for the NSv driver. Using an XL driver will produce an incorrect scale factor and unreliable output.
Q: What is the maximum shaft speed this probe can monitor?
A: The 10 kHz frequency response supports shaft speeds up to approximately 600,000 RPM for 1× vibration; practical limits depend on the monitor’s sampling rate.
Q: Is this probe suitable for stainless steel shafts?
A: The standard calibration targets AISI 4140 steel. Stainless steel (300 series) has different conductivity/permeability and requires a target-material correction factor or a custom calibration.
Q: Do you provide a warranty?
A: Yes — 90-day functional warranty on all units. Extended warranty available upon request.
Q: Can you supply the complete 3300 NSv system (probe + cable + driver)?
A: Yes. Contact us with your cable length and mounting requirements for a complete system quotation.
