Description

Operating on eddy-current principles, the 330103-04-09-10-02-CN proximity sensor is engineered for high-precision, non-contact displacement and vibration measurements. This component belongs to the 3300 XL 8mm series, delivering reliable shaft dynamic vibration, axial position, and speed monitoring under extreme industrial conditions. It serves as a vital sensing element in machinery protection systems, providing continuous diagnostics to ensure the mechanical integrity of critical rotating assets.

The construction combines a chemically inert polyphenylene sulfide (PPS) tip with a robust stainless steel body, ensuring longevity when exposed to lubricating oils, corrosive gases, and high moisture levels. This configuration incorporates a 40mm unthreaded length, 90mm overall case length, and a 1.0-meter integrated standard cable terminating in a ClickLoc miniature coaxial connector.

Features

• Resilient Tip Design: Manufactured from high-performance polyphenylene sulfide (PPS) to withstand harsh process media, operating fluids, and temperature variations.
• Robust Case Construction: AISI 303 or 304 stainless steel (SST) housing provides resistance to physical impact and mechanical stress during installation.
• Secure Interconnects: ClickLoc miniature coaxial connector ensures a reliable, low-impedance connection with standard coaxial extension cables.
• Stable Calibration: Fully compatible with Bently Nevada 3300 XL series Proximitor sensors, preserving calibration consistency over long service lives.

Applications

• Steam and gas turbine shaft vibration and axial position tracking
• Centrifugal and reciprocating compressor monitoring
• Large industrial pump and motor shaft dynamics
• Hydroelectric generator thrust and radial displacement monitoring
• Gearbox input/output shaft speed and runout measurements

Installation Guidelines

• Thread Protection: Avoid over-torqueing the probe during thread engagement to prevent damage to the stainless steel casing and the machine housing threads.
• Minimum Bend Radius: Maintain the recommended minimum bend radius for the integrated coaxial cable (typically 25.4 mm or 1.0 inch) to prevent internal conductor breakage.
• Connector Security: Ensure the ClickLoc connector is clean, dry, and fully locked prior to applying silicone tape or heat-shrink tubing for environmental sealing.
• Clearance Angle: Maintain appropriate side clearance from surrounding metal components to avoid target signal distortion from nearby surfaces.
