Bently Nevada 330101-00-12-10-01-CN 3300 XL 8 mm Proximity Probe

Description

Industrial machinery health monitoring systems rely on the Bently Nevada 330101-00-12-10-01-CN proximity probe to deliver high-precision shaft vibration and position measurements. This probe is a core component of the 3300 XL 8 mm Proximity Transducer System, which operates on eddy current technology to provide an output voltage directly proportional to the distance between the probe tip and the observed target. Designed to interface seamlessly with 3300 XL Proximitor Sensors, it excels in capturing static (position) and dynamic (vibration) measurements on fluid-film bearing machines.

The configuration of this specific model (330101-00-12-10-01-CN) features a 0.0-inch unthreaded length, a 1.2-inch overall case length, a 1.0-meter total length, and is fitted with a miniature coaxial ClickLoc connector with an integrated connector protector. It uses a standard FEP-insulated coaxial cable. Calibrated to an AISI 4140 steel target by default, this transducer system offers complete component interchangeability, eliminating any requirement for user recalibration in the field.

Features

• Complete Interchangeability: Eliminates the need for bench calibration or matching of individual probes, extension cables, and Proximitor sensors.
• TipLoc Molding Technology: Provides a robust, leak-resistant bond between the polyphenylene sulfide (PPS) probe tip and the stainless steel case.
• CableLoc Design: Supplies up to 330 N (75 lbf) pull strength to ensure secure attachment of the probe cable to the probe tip.
• Corrosion-Resistant Connectors: Gold-plated ClickLoc connectors lock securely with finger-tight torque, preventing accidental loosening.
• API 670 Compliance: Fully complies with the mechanical configuration, linear range, accuracy, and temperature stability specifications of the American Petroleum Institute (API) 670 Standard.

Applications

• Fluid-film bearing machines (turbines, compressors, pumps, and generators) for radial vibration and axial position monitoring.
• Keyphasor reference and phase angle measurements.
• Tachometer, speed, and overspeed detection systems.

Technical Specifications

Installation Guidelines

• Connector Torque: ClickLoc connectors require only finger-tight torque. The connectors "click" when they are adequately tightened. Do not use mechanical tools for standard ClickLoc connections.
• Cable Bend Radius: Maintain a minimum cable bend radius of 25.4 mm (1.0 inch) during routing to prevent core damage.
• Thread Engagement: Maximum recommended thread engagement length for 3/8-24 threads is 0.563 inches to prevent binding.
• Connector Protection: Ensure the connector protector is installed properly to guard against dirt, moisture, and potential environmental contamination. Do not use silicone tape if the connection is exposed to turbine oil.

Compliance and Certifications

• EMC: EN 61000-6-2 (Immunity), EN 61000-6-4 (Emissions), Directive 2014/30/EU
