Bently Nevada 330708-00-20-50-02-05 3300 XL 11 mm Proximity Probe, 5m Cable

Description

Product Overview

3300 XL 11 mm Proximity Probes deliver precise radial vibration and position measurements.
Bently Nevada designs these for critical rotating machinery in harsh environments.
The rugged construction ensures reliable data for protection and condition monitoring.

Key Benefits & Diagnostic Capability

• High accuracy – measures static and dynamic displacements with 7.2 Ω ±0.8 probe DC resistance.
• Diagnostic intelligence – built-in tip sense and cable fault detection via coaxial ClickLoc connector.
• Wide frequency response – captures both slow roll and high-speed vibration events.
• Environmental resilience – operates from -51 °C to +177 °C with FEP insulation.
• Interference immunity – triaxial 75 Ω cable design rejects EMI/RFI.

Frequently Asked Questions

• Q: Can I use this 5 m probe with a 1 m Proximitor?
  A: No. The 5‑meter probe must pair with a 5‑meter Proximitor. Matching lengths ensures correct calibration and sensitivity.
• Q: What is the pressure rating of the seal?
  A: Probes are designed to seal differential pressure but are not factory‑tested. Contact our custom department if you need a pressure test.
• Q: How do I choose between armored and unarmored cable?
  A: For high abrasion or severe mechanical stress, choose armored. Standard FEP suits most industrial environments.
• Q: Does the probe work below -34 °C continuously?
  A: Occasional exposure is acceptable, but continuous operation below -34 °C may shorten pressure seal life.
• Q: What is the advantage of ClickLoc connector?
  A: It provides a positive lock without tools, reduces installation time, and resists loosening from vibration.
