Bently Nevada 330173-00-03-10-02-00 – 8mm Eddy Current Proximity Probe | 3300 XL Series Platform
Engineering Background
The Bently Nevada 3300 XL Series represents the industry benchmark for non-contacting shaft vibration and position measurement in rotating machinery. Developed by Baker Hughes (Bently Nevada), this platform is deployed globally in turbines, compressors, pumps, and motors where continuous, high-accuracy rotor dynamic data is mission-critical. The 330173 probe series is the 8mm standard-range transducer within this ecosystem, engineered for direct integration with 3300 XL extension cables and proximitor/driver modules.
Product Positioning
The 330173-00-03-10-02-00 is a factory-configured 8mm eddy current proximity probe with a 1-metre armored cable, metric thread body, and standard sensitivity output. It is the preferred choice for procurement engineers specifying OEM-equivalent replacements or expansion of existing 3300 XL monitoring systems. Konmask.com supplies this part as a verified, traceable unit suitable for critical-service installations.

- Direct OEM Replacement – Pin-compatible with all 3300 XL proximitor/driver modules; no recalibration required when replacing like-for-like
- Long Service Life – Non-contacting measurement eliminates wear; MTBF exceeds 100,000 hours in typical installations
System Architecture & Signal Flow
The 330173-00-03-10-02-00 operates as the sensing element in a three-component transducer system:
- Proximity Probe (330173-00-03-10-02-00) – Generates the eddy current field and converts gap distance to a proportional voltage signal via the integral coaxial cable.
- Extension Cable (330130 Series) – Transmits the high-frequency oscillator signal between probe and proximitor over distances up to 9 m total system cable length.
- Proximitor / Driver (3300 XL 8mm, e.g. 330180) – Provides −24 VDC excitation, demodulates the RF signal, and outputs a DC voltage proportional to gap. Interfaces directly with 3500 Series monitoring racks or standalone monitors.
Total system cable length (probe + extension) must not exceed 9.0 m for specified sensitivity. Verify proximitor part number compatibility before ordering extension cables.

Technical FAQ
Q: Can the 330173-00-03-10-02-00 be used with older 3300 (non-XL) proximitors?
A: The 3300 XL 8mm probe series is designed for XL-series proximitors. Cross-compatibility with legacy 3300 drivers requires sensitivity verification; contact our engineering team for guidance.
Q: What is the maximum operating temperature for the probe cable?
A: The integral armored cable is rated to +120 °C continuous. For higher ambient temperatures at the cable routing path, specify a high-temperature extension cable (330130-XX-XX series).
Q: Is factory calibration documentation available?
A: Yes. Original Bently Nevada calibration certificates can be requested at time of order for new-surplus units. Reconditioned units include Konmask.com in-house calibration reports traceable to NIST standards.
Q: What target materials require special calibration?
A: The standard calibration is for AISI 4140 steel. Stainless steel, titanium, Inconel, and other alloys require material-specific calibration factors. Bently Nevada provides calibration curves for common alloys; contact us to specify your target material.
Q: Do you offer expedited shipping for critical plant shutdowns?
A: Yes. Express air freight is available globally. Contact [email protected] with your required delivery date and we will confirm availability and logistics options within 2 business hours.
