330104-00-08-50-02-00 3300 XL 8mm Armored Proximity Probe | Bently Nevada

Product Overview

The Bently Nevada 330104-00-08-50-02-00 functions as a high-precision eddy current sensor for non-contacting shaft displacement and vibration measurements. As a core component of the 3300 XL ecosystem, this 8mm probe provides the critical data required for radial vibration, axial thrust, and phase reference (Keyphasor) monitoring. We supply this unit as 100% Brand New and Original, ensuring your protection system operates with OEM-certified accuracy and linearity.

Engineering Advantages

The 330104-00-08-50-02-00 provides specific mechanical solutions for complex industrial installations:

• Physical Damage Mitigation: The integrated stainless steel armor protects the coaxial cable from sharp edges, hot metal shavings, and heavy-duty maintenance activities that often sever unshielded lines.

• Simplified Installation: The 5.0-meter total length often allows direct connection to a junction box or Proximitor® without requiring an intermediate extension cable, reducing potential failure points in the signal loop.

• Locking Signal Integrity: The ClickLoc™ connector features a mechanical locking mechanism that prevents accidental disconnection or signal attenuation caused by high-frequency machinery vibration.

• Extreme Chemical Resistance: The PPS tip withstands synthetic lubricants and corrosive process fluids, preventing tip erosion and maintaining the pressure seal between the probe head and the case.

FAQs

• Can I install this probe into a machine with high internal pressure?

  Yes. The 3300 XL 8mm probes incorporate a Viton® O-ring to seal differential pressure between the tip and the case. If your application exceeds standard industrial pressures, contact our technical team for specific seal testing data.

• How do I ensure the correct gap setting for this 5.0m probe?

  Connect the probe to a 3300 XL Proximitor® and monitor the DC output. Adjust the probe position until you reach the specified voltage (typically -10.0 Vdc for the center of the linear range) before tightening the locknut.

• Is the armor flexible enough for tight conduit bends?

  The stainless steel armor provides excellent protection while maintaining sufficient flexibility for standard industrial routing. However, avoid exceeding the minimum bend radius of 25.4 mm (1 inch) to prevent internal coaxial damage.

• Can this model replace older 3300 series probes?

  Yes. The 3300 XL series offers full backward compatibility with non-XL 3300 systems. It provides improved scale factor linearity and better temperature stability compared to the legacy 3300 series.
