Product Overview

The Bently Nevada 330101-00-34-15-02-05 is a precision-engineered 8mm proximity transducer probe designed for non-contact displacement and vibration measurements. As a core element of the 3300 XL Proximity Transducer System, this eddy current sensor monitors the gap between the probe tip and the target material, typically a rotating shaft. It is a fundamental component for Turbine Supervisory Instrumentation (TSI), providing critical data for radial vibration monitoring, axial thrust position, and tachometer speed measurements.

This specific configuration utilizes a 3/8-24 UNF threaded housing with a 3.4-inch case length and a 1.5-meter integral cable. Its robust design ensures high-accuracy signal transmission in the extreme conditions of industrial power plants and refineries, where mechanical reliability is paramount for machinery protection.

Technical Characteristics and Construction

The 3300 XL series is recognized for its industry-leading performance in harsh environments, featuring several proprietary technologies that enhance service life and data integrity.

• Advanced Mechanical Bonding: The probe employs TipLoc molding, which creates a chemical and physical bond between the probe tip and the body, preventing tip separation. CableLoc technology ensures the cable can withstand pull forces up to 220 N (50 lb).

• Signal Precision: Designed for maximum EMI/RFI immunity, the probe operates without interference in proximity to heavy electrical equipment, meeting stringent CE standards for electromagnetic compatibility.

• Corrosion Resistance: The gold-plated ClickLoc connector system provides a low-resistance connection that is resistant to oxidation and remains secure even under intense vibration.

• Installation Efficiency: The internal design provides built-in electrical isolation, removing the need for external isolator plates when mounting to a machine casing.

• System Integration: It is fully backward compatible with earlier 3300 series systems, allowing for seamless integration into existing monitoring infrastructures during maintenance or upgrades.
