Bently Nevada 330101-33-53-10-02-05 3300 XL 8 mm Proximity Probe

Description

The 330101-33-53-10-02-05 is a 3300 XL 8 mm proximity probe, configured with a 3/8-24 UNF thread, a 3.3 in. unthreaded length, and a 5.3 in. total case length. This probe is a core element of the Bently Nevada 3300 XL 8 mm transducer system, engineered for non-contact eddy-current displacement measurement, making it suitable for monitoring shaft vibration and axial position on critical rotating machinery such as turbines, compressors, and pumps.

This specific configuration utilizes a 1.0-meter total system length (Option 10) and features the Miniature coaxial ClickLoc connector with standard cable (Option 02) for reliable signal transmission. It is rated with CSA, ATEX, and IECEx hazardous area approvals (Option 05), ensuring compliance for installation in demanding industrial environments where explosive atmospheres may be present. The 3300 XL system is fully backward compatible with earlier 3300-series components, providing a seamless upgrade path for existing machinery protection installations.

Installation Guidelines

Ensure the probe is installed in an appropriate housing or bracket, maintaining the required air gap from the observed surface. Secure the ClickLoc connector firmly to the extension cable to ensure signal integrity. For hazardous area installations, adhere to the specific Bently Nevada control drawings (141092 for ia, 140979 for nA/ec) to ensure the system remains within certified parameters. Avoid over-tightening the probe mounting threads to prevent structural damage.
