Description

The Bently Nevada 330101-00-44-10-02-05 is a high-performance, non-contact 8 mm proximity probe designed as a core component of the 3300 XL 8 mm Proximity Transducer System. This specific model configuration features an unthreaded length of 0.0 inches and an overall case length of 4.4 inches, terminated with a 1.0-meter standard coaxial cable and a miniature ClickLoc coaxial connector. It is engineered with the -05 Agency Approval Option, certifying it for hazardous areas under CSA, ATEX, and IECEx standards. By utilizing the eddy-current operating principle, the probe enables highly precise non-contact vibration and shaft position measurements. It interfaces seamlessly with a 330180 series Proximitor sensor and extension cable to form an integrated machinery protection and condition monitoring loop, making it highly suitable for installations on critical rotating machinery where mechanical armor is not required.

Technical Specifications

Installation Guidelines

• Mount the proximity probe using the recommended probe gap per system calibration specifications (typically 1.27 mm or 50 mils over the target area).
• Ensure target material matches AISI 4140 steel unless the transducer system has been specifically calibrated to an alternative target.
• Limit the maximum thread engagement length to 1.5 times the nominal thread diameter to prevent binding during installation.
• Exposing the probe to temperatures below -34 degC (-30 degF) may degrade or compromise the internal Viton pressure seal.
• Route the standard coaxial cable securely using proper shielding, grounding, and conduit protection to prevent electrical noise interference.

Compliance and Certifications

• CSA: Approved for hazardous locations.
• ATEX: Certified for explosive gas and dust atmospheres (Ex ia IIC T5...T1 Ga / Ex nA IIC T5...T1 Gc / Ex ec IIC T5...T1 Gc).
• IECEx: Globally certified for intrinsically safe and non-sparking hazardous areas.
