Bently Nevada 330103-00-05-50-12-00 3300 XL 8 mm Proximity Probe
The Bently Nevada 330103-00-05-50-12-00 is a high-reliability 3300 XL 8mm proximity probe designed for non-contact shaft displacement measurement and radial vibration monitoring in critical rotating machinery. As a core component of API 670 compliant protection systems, it ensures maximum uptime for steam turbines, compressors, and pumps.
- High-Precision Monitoring: Engineered for axial thrust position and shaft vibration monitoring, delivering a stable scale factor of 7.87 V/mm (200 mV/mil) calibrated for AISI 4140 steel.
- Rugged Mechanical Design: Features a fully threaded M10 x 1 metric thread probe (50mm case length / 0mm unthreaded) for precise gapping and easy installation.
- FluidLoc & ClickLoc Technology: Equipped with a miniature coaxial ClickLoc connector and an advanced FluidLoc cable that stops oil and process fluids from leaking through the wire strands.
- 5-Meter System Length: Unarmored 5.0-meter configuration designed for direct, seamless integration with Bently Nevada 3500 rack modules and 3300 XL Proximitor sensors.
Frequently Asked Questions
Q1: What are the exact physical dimensions and thread specifications of the Bently Nevada 330103-00-05-50-12-00 proximity probe?
A: The 330103-00-05-50-12-00 is a 3300 XL 8 mm probe, forward mount, M10 x 1 thread. Pretty standard. “00” means no unthreaded section, fully threaded body. “05” gives 50 mm case length. In most cases it’s just treated as a 5.0 m system length probe.
Q2: Does the Bently Nevada 330103-00-05-50-12-00 probe require an external extension cable for system integration?
A: No. It already comes as a 5.0 meter system length, so it connects directly to a 3300 XL Proximitor sensor like 330180-50 series. No extension cable in between. People usually don’t add one anyway, since changing length can affect calibration a bit in radial vibration monitoring or shaft displacement measurement.
Q3: What specific cable and connector technologies are utilized in the 330103-00-05-50-12-00 model?
A: It uses “12” ClickLoc connector with FluidLoc cable. Not much to explain here. FluidLoc just blocks oil or moisture from moving through the cable. Common in industrial rotating machinery, where contamination shows up often. Helps keep eddy current sensor signals stable.
Q4: What are the calibration and measurement standards for the Bently Nevada 330103-00-05-50-12-00?
A: Used for non-contact shaft displacement, also radial vibration monitoring, sometimes axial thrust position. Calibration on AISI 4140 steel target. Range about 2.0 mm (80 mils), sensitivity 200 mV/mil (7.87 V/mm). Fits directly into API 670 system with Bently Nevada 3500 system, no extra setup.
Q5: What hazardous area certification does the 330103-00-05-50-12-00 probe hold?
A: “00” means no hazardous approvals. So only standard industrial use. For ATEX / IECEx / CSA, you need a different variant, especially for refinery or ESD systems. This one is just normal 3300 XL 8 mm probe type.
