Features:

  • ClickLoc™ Secure Connectivity
  • Patented Structural Integrity
  • High RFI/EMI Immunity
Designed for high-vibration environments, the ClickLoc™ mechanism provides a positive "click" feedback upon secure engagement. This gold-plated connector system eliminates loosening issues common with threaded connectors, ensuring long-term signal integrity without specialized tools.

Featuring a robust TipLoc and CableLoc design, the Bently Nevada 330101-00-77-20-02-CN withstands a 330N (75 lbf) pull force. This ruggedization protects the probe tip and cable lead from mechanical stress, physical abuse, and severe operational vibrations found in large turbomachinery.

Engineered to exceed international CE mark standards, this transducer system offers superior radio frequency immunity. It can be installed in fiberglass or non-metallic housings without the costly requirement for shielded conduits, simplifying installation and reducing overall project complexity.

The 330101-00-77-20-02-CN Bently Nevada 3300 XL 8mm Proximity Transducer System may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
