330103-02-12-05-02-CN Bently Nevada 3300 XL 8 mm Proximity Probe
Product Overview
The Bently Nevada 3300 XL 8 mm Proximity Probe is a premium, non-contact eddy current sensor engineered for precise vibration, position, and speed measurements on fluid-film bearing machinery. It delivers an output voltage directly proportional to the static or dynamic distance between the probe tip and the observed conductive target. Fully compliant with the American Petroleum Institute's API 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability, this system offers maximum protection for critical industrial assets.
Model Configuration Breakdown
Base Part Number (330103): 3300 XL 8 mm Metric Probe, M10 x 1 thread, without armor.
Unthreaded Length Option (02):20 mm unthreaded body case.
Overall Case Length Option (12):120 mm total threaded/unthreaded case housing.
Total Cable Length Option (05):0.5 meter (1.6 feet) integral probe lead.
Connector and Cable-Type Option (02): Miniature coaxial ClickLoc connector, standard triaxial cable without connector protector.
Agency Approval Option (CN): Specific national industrial and hazardous area safety certifications for China.
Key Features & Benefits
Advanced Mechanical Robustness: Featuring a high-performance Polyphenylene Sulfide (PPS) molded plastic tip and a patented TipLoc molding bond, the probe is built for rugged durability. The CableLoc design secures the connection with up to 330 N (75 lbf) of pull strength.
Complete Interchangeability: All 3300 XL 8 mm components support complete interchangeability among matching lengths of probes, extension cables, and Proximitor sensors, completely eliminating the need for tedious bench calibration. It is also fully backward compatible with non-XL 3300 series 5 mm and 8 mm components.
Secure ClickLoc Connectors: Outfitted with corrosion-resistant, gold-plated ClickLoc connectors that provide a secure, finger-tight locking mechanism. They dynamically click when locked into place, preventing loose connections from heavy machinery vibration without requiring specialized installation tools.
Extreme Environment Ready: Built to perform in demanding settings with a wide standard probe operating temperature range of -52°C to +177°C (-62°F to +350°F).
Global Distribution
Amikon delivers premium industrial automation spare parts—principally PLC, DCS, and TSI systems—to over 160 countries across major global regions:
North America (United States, Canada, Mexico) — oil & gas side is pretty active, and automotive plants also show up a lot in shipments.
Europe (Germany, UK, France, Italy) — more on machinery lines and chemical plants, nothing too surprising here, but demand stays consistent.
Middle East & Africa (UAE, Saudi Arabia, South Africa) — refineries mostly, plus mining projects in harsher environments where equipment reliability matters.
Asia-Pacific (China, Singapore, Australia, India) — quite mixed, from semiconductor fabs to metallurgy and power stations, depends on the country.
South America (Brazil, Chile, Argentina) — mining is the big one, especially copper-related projects, hydropower also comes up from time to time.

Frequently Asked Questions
Q1: How to do gap calibration during installation of 330103-02-12-05-02-CN?
A1: Field setup is mostly about finding the right midpoint of the linear range. The Bently Nevada 330103-02-12-05-02-CN 3300 XL 8mm Proximity Probe usually runs within a 2 mm span, so engineers just adjust the probe position while watching the Proximitor sensor output.
When the DMM sits around the reference point (roughly -9 Vdc), that’s generally the sweet spot — around 1.27 mm / 50 mils gap. At that stage, the M10x1 thread proximity probe Bently Nevada is locked with the dual nuts and left in place.
Q2: Can 330103-02-12-05-02-CN work with older 3300 systems?
A2: Yes, in most cases. The 330103-02-12-05-02-CN probe still fits older non-XL Bently Nevada 3300 XL system spares setups.
But in real plant work, mixing new probe + old electronics usually means the system performance follows the weaker side — things like accuracy and stability won’t fully match API 670 levels anymore.
Q3: How to build the full loop length for 330103-02-12-05-02-CN?
A3: This version comes with a 0.5 m cable, so it’s basically the probe head only. To complete the loop, it connects through ClickLoc gold-plated connector to a 330130 extension cable integration.
Most common setups:
0.5 m probe + 4.5 m cable → standard 5 m loop
or 0.5 m probe + 8.5 m cable → longer monitoring runs
This keeps the eddy current transducer impedance balanced in the Bently Nevada 3500 rack module system.
Q4: What happens on different shaft materials with 330103-02-12-05-02-CN?
A4: Factory calibration is based on AISI 4140 steel. If the rotor is stainless steel or other alloys, the reading can drift a bit. It won’t break anything, but the radial vibration monitoring scale factor may shift slightly.
In critical steam turbine rotor vibration or compressor cases, engineers sometimes do recalibration or apply correction curves for more accurate non-contact shaft displacement data.
Q5: How to check the 330103-02-12-05-02-CN health during shutdown?
A5: Quick field check is resistance measurement. Disconnect the ClickLoc connector cable and measure across the probe.
A healthy 330103 proximity probe usually sits around 7.45 ohm (± small tolerance).
Open circuit → likely broken coil inside
Near zero → short circuit
In both cases, it’s basically a replacement situation, especially in machinery protection system (MPS) or ESD critical asset protection setups.
