Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or equivalents for the 330903-00-24-50-02-00. Always verify gap voltage, scale factor, and cable length before substitution:
- Bently Nevada 330903-00-24-10-02-00 — Same transducer, 10 ft extension cable (shorter run)
- Bently Nevada 330903-00-24-30-02-00 — 30 ft extension cable variant
- Bently Nevada 330905-00-24-50-02-00 — 3300 XL 8 mm standard series, compatible driver/monitor
- Bently Nevada 330780-50-00 — 3300 5 mm proximity transducer (different thread; verify monitor compatibility)
- Epro PR6423/010-040 — Third-party equivalent, 8 mm eddy-current, verify scale factor 8 V/mm
- Metrix ST5484E — Alternative proximity system; confirm monitor input range before use
⚠ Note: Cross-brand substitutions require full system validation including driver, extension cable, and monitor compatibility. Contact our engineers at support@konmask.com for a free compatibility check.
Why Choose the Original Model
- Factory-calibrated scale factor — 200 mV/mil ensures direct plug-in compatibility with Bently Nevada 3300 series monitors (3300/16, 3300/20, 3500/42)
- NSv (Non-Standard velocity) optimized — Designed for low-frequency shaft vibration measurement in steam turbines, compressors, and pumps
- Integral cable design — Eliminates connector failure points in harsh industrial environments
- API 670 compliant — Meets machinery protection standard for critical rotating equipment
- Long field service life — Robust stainless-steel housing rated for high-temperature, high-vibration zones
Typical Applications
- Steam turbine shaft radial vibration monitoring
- Centrifugal compressor rotor position measurement
- Pump and motor bearing displacement monitoring
- Gearbox differential expansion measurement
- Turbine thrust position monitoring
- Petrochemical plant rotating machinery protection systems
System Compatibility
The 330903-00-24-50-02-00 transducer is designed to operate within the complete Bently Nevada 3300 XL NSv system, which includes:
- Driver/Oscillator: Bently Nevada 330180-X1-05 (3300 XL NSv driver)
- Extension Cable: Bently Nevada 330130-045-00-CN (50 ft, included in this configuration)
- Monitors: 3300/16, 3300/20, 3500/42M, 3500/42 (radial vibration monitors)
- System: Bently Nevada System 1 / System 1 Evolution (condition monitoring software)
Do not mix NSv transducers with standard 3300 XL drivers — the scale factor and gap voltage differ. Confirm driver part number before installation.

Replacement & Compatibility FAQ
Q: Can I use a standard 3300 XL transducer instead of the NSv version?
A: No. The NSv (Non-Standard velocity) series uses a different scale factor and requires a matched NSv driver. Mixing series will result in incorrect vibration readings and potential monitor alarms.
Q: Is the 330903-00-24-50-02-00 compatible with the Bently Nevada 3500 system?
A: Yes, when paired with the 3500/42M or 3500/42 monitor module and the correct NSv driver. Verify the monitor’s input configuration before installation.
Q: What is the gap voltage for this transducer?
A: The recommended gap voltage is approximately −10.0 VDC (corresponding to a 50 mil / 1.27 mm gap on AISI 4140 steel target).
Q: Can Konmask supply the complete 3300 XL NSv system (transducer + driver + cable)?
A: Yes. Contact us with your system requirements and we will quote the complete assembly.
Q: Do you offer a warranty?
A: All units carry a minimum 12-month warranty against manufacturing defects. Extended warranty options available for project orders.
