Bently Nevada 330185-02 3300 XL Precision Micrometer

Description

The Bently Nevada 330185-02 is a 3300 XL Precision Micrometer configured in metric units (0–25 mm). It serves as a verification tool designed for acceptance testing and performance verification of eddy current proximity transducer systems according to original published specifications or American Petroleum Institute standard API 670.

The device checks transducer system performance by holding a probe in a dedicated mounting adapter while moving a high-precision AISI 4140 steel target button toward or away from the probe tip in measured increments, simulating shaft movement. By reading the corresponding output voltage from the Proximitor Sensor using a voltmeter, users can generate a voltage-versus-gap curve to evaluate linear range, average scale factor (ASF), incremental scale factor (ISF), and deviation from straight line (DSL). Additionally, the system provides verification capabilities for shaft position monitoring equipment.

Features

• High-Precision Calibration: Designed for precise measurement and curve generation to verify transducer linear range, ASF, ISF, and DSL specifications.
• Standardized Target Material: Utilizes a precision ground AISI 4140 alloy steel target button to match standard machinery target characteristics.
• Modular Probe Adapters: Accommodates various probe thread sizes including 1/4 inch, 3/8 inch, 1/2 inch, 5/8 inch, M8, M10, M14, and M16 using standard mounting collets/adapters.
• Standard Compliance: Facilitates field or laboratory verification testing compliant with API 670 guidelines.

Applications

• Field verification of proximity probe and Proximitor Sensor transducer systems.
• Factory and laboratory acceptance testing of 3300 XL transducer components.
• Calibration and operation verification of shaft position and machinery protection monitors.

Installation Guidelines

• Probe Setup: Select the correct probe mounting adapter corresponding to the probe thread size (e.g., M8, M10, 3/8 inch) and secure the probe firmly in the holder.
• Zero Calibration: Verify target button condition and clean the surface before zeroing or commencing measurements.
• Mechanical Stability: Ensure the unit is positioned on a flat, stable, vibration-free surface during test procedures to prevent reading variations.
