Bently Nevada 330104-00-12-10-02-00 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330104-00-12-10-02-00 is a brand new, original 3300 XL 8 mm proximity probe engineered with an extended threaded casing. This rugged sensor utilizes eddy current technology to capture precise static (gap) and dynamic (vibration) measurements of rotating shafts. It serves as the primary data-gathering component for continuous machinery protection layouts, tracking radial vibration and axial thrust position on large industrial assets like steam turbines, gearboxes, and turbo-compressors. This genuine, US-manufactured probe provides stable, noise-free input signals directly to standard Bently Nevada Proximitor sensors and monitoring racks.

Part Number Breakdown

Bently Nevada manufactures this hardware configuration to accommodate deep mounting profiles and standard cabling paths:

Engineering Advantages

• Bypasses Deep Housing Obstructions: The extended 120 mm fully threaded casing solves difficult spatial constraints. This long-reach profile allows installation through thick machine castings or water-jacketed bearing housings, reaching internal shaft target areas without requiring separate custom sleeve extensions.

• Defends Interfacial Runs from Physical Stress: The integral stainless steel armor sleeve surrounds the core coaxial line. This protective jacket guards the cable path against sharp housing burrs, hot metal shavings, and regular maintenance foot traffic near the machine casing.

• Withstands Turbulent Industrial Fluids: A specialized high-performance polyphenylene sulfide (PPS) tip molds securely over the probe coil. This structural plastic prevents moisture ingress and resists chemical degradation from synthetic lubricants, ensuring linear measurement stability across rapid temperature cycles.

• Eliminates Vibration-Induced Connector Disconnects: The ClickLoc coaxial connector features a built-in mechanical lock. Field operators mate the connection by hand with a clear tactile click, establishing a high-strength union that eliminates signal disruption caused by continuous, high-amplitude machine frame vibration.

FAQs

• Can I pair this 1.0-meter probe directly with a 5-meter Proximitor sensor?

  No. You must add a 4.0-meter 3300 XL extension cable between this probe and a 5-meter Proximitor sensor. The total hardware length must equal exactly 5.0 meters to satisfy the system's electrical inductance calibration and maintain the accurate 200 mV/mil scale factor.

• How should I handle the physical positioning of the probe during the initial installation gap adjustment?

  Connect the probe to its calibrated system and supply power. Thread the probe slowly toward the target shaft while monitoring the DC voltage output on the Proximitor sensor. Stop rotation once the multimeter displays the specified target bias voltage (typically -9.0 VDC for the center of the linear range), then tighten the locknuts.

• What is the maximum temperature rating for this probe tip and armored cable assembly?

  The probe tip and armored cable withstand continuous operating temperatures from -51°C to +177°C (-60°F to +350°F). Exceeding this thermal threshold de-calibrates the sensor coil and breaks down the internal cable insulation.
