Engineering Background: The Bently Nevada 3300 XL NSv (Non-Standard voltage) Proximity Transducer System is a precision eddy-current sensing solution engineered for continuous, non-contact measurement of shaft radial vibration, axial position, and differential expansion in rotating machinery. Developed under Baker Hughes’ Bently Nevada product line, the 3300 XL series represents decades of field-proven reliability in critical turbomachinery protection and condition monitoring applications.
Product Positioning: Part number 330903-00-10-05-01-00 is a complete transducer system comprising a 10 mm diameter probe, 5 m (16 ft) armored integral cable, and 1 m (3.3 ft) extension cable. It is designed to interface directly with Bently Nevada 3300 XL signal conditioning monitors and is fully compatible with the System 1 and 3500 Series monitoring platforms. This configuration is widely specified in OEM turbine, compressor, and pump protection systems worldwide.

System Architecture & Signal Flow
The 330903-00-10-05-01-00 operates as part of a three-component eddy-current chain:
- Probe (330903 series) — Generates a high-frequency electromagnetic field (typically 1 MHz oscillator). As the conductive target (shaft) moves within the field, eddy currents are induced, altering the probe’s impedance.
- Extension Cable (330130 / 330180 series) — Transmits the demodulated signal from the probe to the driver/oscillator. Total system cable length is calibrated; the 5 m + 1 m configuration (6 m total) is factory-matched.
- Driver / Oscillator-Demodulator — Converts impedance changes into a DC voltage proportional to gap distance. The NSv driver outputs a nominal –24 VDC at mid-gap, with sensitivity of 7.87 V/mm.
The output feeds directly into a Bently Nevada 3300 XL monitor card (e.g., 3300/16, 3300/20, 3300/25) or a 3500 Series rack-mounted monitor, which performs alarm, danger, and relay logic per API 670 setpoints.

Technical FAQ
Q: Can the 330903-00-10-05-01-00 replace a 330903-00-10-05-02-00?
A: The last digit denotes the driver/oscillator variant. Confirm the driver part number before substitution; NSv and standard voltage (Sv) drivers are not interchangeable without monitor card reconfiguration.
Q: What is the maximum total cable length for this system?
A: The 3300 XL NSv system is calibrated for a specific total cable length. The 5 m integral + 1 m extension = 6 m total is a factory-matched set. Do not add additional extension cables without recalibration.
Q: Is this probe suitable for non-ferrous targets?
A: Yes, but sensitivity will differ from the standard AISI 4140 calibration. A target material correction factor or field recalibration is required for aluminum, titanium, or Inconel shafts.
Q: What monitor cards are compatible?
A: 3300/16, 3300/20, 3300/25, 3300/46, 3300/50 (XL NSv input cards); 3500/40M, 3500/42M, 3500/44M, 3500/46M (3500 Series with NSv input configuration).
Q: Can Konmask provide a calibration certificate?
A: Yes. Factory calibration documentation is available for all new units. Third-party NIST-traceable recalibration can be arranged upon request.
