Bently Nevada 330101-02-21-10-01-00 3300 XL 8 mm Proximity Probe

Description

Features

• Proximity tip diameter of 8 mm designed for precise non-contact eddy-current displacement measurements.
• Integrated connector protector (option 01) safeguarding the miniature ClickLoc coaxial connection against oil, moisture, and contaminants.
• Unarmored stainless steel threaded body (3/8-24 UNF) designed for bearing housing or machine casing mount.
• Compact 0.2 in unthreaded length and 2.1 in case length for tight mechanical clearance installations.
• 1.0 meter total cable length (standard coaxial) suited for neat connection to local junction boxes.
• Excellent thermal performance and mechanical durability across harsh industrial rotating environments.

Applications

• Steam and gas turbine shaft vibration and axial position measurement.
• Rotor dynamic displacement monitoring in large compressors and industrial pumps.
• Bearing oil film clearance and thickness monitoring.
• Radial vibration, thrust position, and speed sensing on high-speed rotating shafts.

Installation Guidelines

• Probe Gap Calibration: Mount the probe with the correct initial mechanical gap (typically 1.27 mm or 50 mils) to target the midpoint of the Proximitor sensor's calibrated linear voltage range.
• Thread Integrity: Use care when threading the probe into brackets or casings. Do not exceed recommended tightening torque to prevent thread damage.
• Cable Protection: Route the standard unarmored coaxial cable inside rigid or flexible conduit to protect it from mechanical wear, pinching, and high temperatures.
• Connector Protection: Verify that the integrated connector protector is properly seated to insulate the ClickLoc junction from lubricating oil, moisture, and debris.
• Grounding and Shielding: Properly terminate cable shields at the instrument/monitor end of the loop only, preventing ground loops that introduce electronic noise.
