Proven Application Environments
- Steam & Gas Turbines – continuous shaft orbit and vibration trending per API 670
- Centrifugal Compressors – radial bearing clearance monitoring in LNG and refinery trains
- Boiler Feed Pumps – axial thrust position measurement in high-temperature, high-pressure service
- Large Electric Motors & Generators – rotor eccentricity and differential expansion tracking
- Gearboxes – gear mesh frequency analysis in conjunction with 3300 XL monitors
- Hydro Turbines – slow-speed shaft runout measurement in hydro-electric installations
Engineering Advantages
- Non-Contact Measurement – zero mechanical wear; suitable for continuous 24/7 operation
- Wide Frequency Bandwidth (DC – 10 kHz) – captures slow-roll runout and high-frequency sub-synchronous instabilities in a single channel
- NSv Output Compatibility – direct integration with 3300 XL NSv extension cables and monitor cards; no field re-calibration required for like-for-like replacement
- 316 SS Enclosure – resists H₂S, chloride-bearing atmospheres, and process fluid splash
- IP67 Sealing – maintains calibration integrity in wash-down and condensing-moisture conditions
- API 670 Compliant Signal Chain – supports machinery protection system certification audits
System Architecture & Signal Flow
The 330904-00-22-10-01-00 operates as the sensing element in a three-component eddy-current system:
- Proximity Transducer (this unit) – generates a high-frequency oscillating magnetic field; shaft proximity modulates the field and produces a DC-biased AC output voltage proportional to gap distance.
- Extension Cable (3300 XL NSv series) – low-loss coaxial cable transmits the raw transducer signal to the proximitor/oscillator; cable length must match PN segment “-22-” (22 in).
- Proximitor / Oscillator (3300 XL NSv) – conditions the signal, provides oscillator drive, and outputs a calibrated voltage to the monitor card (typically –24 VDC bias at mid-gap).
Note: All three components must be from the same NSv sub-family. Mixing standard and NSv components will introduce measurement error.
Sourcing & Quality Verification

Technical FAQ
Q: Can I use this transducer with a standard (non-NSv) 3300 XL proximitor?
A: No. The NSv sub-family uses a different output voltage range. Mixing components will produce calibration errors and may trigger false alarms or missed trips.
Q: What target material is this transducer calibrated for?
A: Factory calibration is performed on AISI 4140 steel. For other alloys (e.g., 17-4 PH stainless, Inconel), a field calibration or correction factor is required per Bently Nevada application note.
Q: Is the “-22-” in the part number the cable length?
A: Yes. “330904-00-22-10-01-00″ indicates a 22-inch (559 mm) integral cable. Confirm your installation geometry accommodates this length before ordering.
Q: Do you provide a Certificate of Conformance?
A: Yes. A CoC is available upon request at no additional charge. Please specify your requirements at the time of order.
Q: What is the minimum order quantity?
A: Single-unit orders are accepted. Volume discounts apply for orders of 3 units or more — contact us for a tiered pricing schedule.
