Bently Nevada 330701-00-15-10-02-05 – Eddy Current Proximity Transducer System | 3300 XL Series
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for non-contact shaft vibration and position measurement in rotating machinery. Engineered for continuous operation in harsh industrial environments, this proximity transducer system delivers the signal fidelity and long-term stability demanded by API 670-compliant machinery protection systems worldwide.
Product Positioning
The 330701-00-15-10-02-05 is a complete eddy current proximity transducer system comprising a 5mm probe tip, 5-metre (16.4 ft) armored integral cable, and 2-metre (6.6 ft) extension cable — factory-matched and calibrated as a system. It is the preferred choice for procurement engineers specifying vibration, axial position, differential expansion, and eccentricity measurements on turbines, compressors, pumps, and motors.

- Wide Frequency Bandwidth — DC to 10 kHz captures sub-synchronous, synchronous, and high-frequency events
- Non-Contact Measurement — Zero mechanical wear; suitable for continuous 24/7 operation
- High Temperature Probe — Rated to +177°C for hot-section and exhaust-end installations
- API 670 Compliant — Drop-in compatible with Bently Nevada 3500 and 3300 series monitor racks
- Armored Cable — Stainless steel armor protects against mechanical damage and EMI in industrial environments
System Architecture & Signal Flow
The 330701-00-15-10-02-05 operates as a three-component eddy current system:
- Probe (330701 series) — Generates a high-frequency electromagnetic field at the tip; eddy currents induced in the target shaft modulate the field proportional to gap distance.
- Extension Cable (330130 / 330180 series) — Transmits the RF signal from probe to driver with matched impedance; length is factory-specified in the part number.
- Driver / Oscillator-Demodulator — Converts the modulated RF signal to a DC voltage output (–1 to –17 VDC); output feeds directly to Bently Nevada 3500 or 3300 monitor input cards.
The complete system is calibrated on AISI 4140 steel targets. For non-standard target materials (Inconel, titanium, stainless), a material correction factor must be applied — consult the Bently Nevada application engineering team or reference TIL-073.

Technical FAQ
Q: Is this a complete system or just the probe?
A: This listing is for the complete factory-matched system: probe + integral cable (5 m) + extension cable (2 m). The driver/oscillator-demodulator is sold separately if not already installed in your monitor rack.
Q: Which Bently Nevada monitors is this compatible with?
A: Compatible with Bently Nevada 3500/40M, 3500/42M, 3300/16, and all standard 3300 XL monitor cards that accept –24 VDC powered proximity inputs.
Q: Can I use this with a non-Bently Nevada monitor?
A: Yes, provided the monitor accepts a –1 to –17 VDC output at 200 mV/mil sensitivity. Consult your monitor manufacturer’s input specifications.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. Contact us for current inventory status.
Q: Do you provide calibration certificates?
A: Factory calibration is inherent to the matched system. Third-party recalibration certificates can be arranged upon request at additional cost.
