The 330186-02 is an essential tool utilized for performing acceptance testing and field verification on proximity transducer systems. This metric version provides a 0 to 25 mm range with a 0.01 mm resolution and ±0.003 mm accuracy, ensuring full compliance with the transducer's performance specifications and the American Petroleum Institute's Standard API 670.
True Shaft-Targeting
Compliant with API 670 standard
If offline testing is required, it can be converted into a standard workstation/desktop calibrator at any time
Unlike benchtop units, the 330186-02 Shaft Micrometer is primarily utilized to check the output signal of a Proximitor Sensor directly against the actual rotor shaft or a reciprocating compressor piston rod. During operation, a specialized strap attaches to a mounting base, wrapping tightly around the target shaft to hold the mechanism firmly in position.
A probe mounting adapter holds the probe within the mounting base, while the spindle micrometer precisely adjusts the probe's distance relative to the shaft surface in specific metric increments. By recording the voltage output from the Proximitor Sensor using a voltmeter, technicians can instantly plot a newly generated calibration curve. This allows for a direct comparison with published specifications—verifying critical metrics such as linear range, average scale factor (ASF), incremental scale factor (ISF), and deviation from straight line (DSL) under real-world machine conditions. Additionally, it serves as a reliable solution for verifying the proper operation of shaft position monitors.

Oil & Gas Exploration and Production
Used on offshore drilling platforms and onshore gathering stations for gas compressors and water injection pumps to perform in-situ calibration of shaft displacement probes, preventing high-pressure false trips.
Petrochemical and Refining
Verifies eddy current sensors on core rotating equipment like cracked gas compressors and hydroprocessing feed pumps, ensuring shaft vibration monitoring meets API 670 standards in extreme high-temperature and high-pressure environments.
Thermal Power Generation
Mounted directly onto the main shafts of steam turbines and generators in coal-fired or gas-fired power plants to calibrate axial position (differential expansion/thrust) and shaft vibration probes, safeguarding grid power supply.
Nuclear Power Generation
Used for periodic static verification of proximity probe loops on main feedwater pumps, reactor coolant pumps (MCP), and high-capacity turbine units outside the nuclear island, complying with strict nuclear safety regulations.
Hydroelectric Power Generation
Tailored for the low-speed, large-diameter shafts of large hydro-generator units, strapped directly to vertical or horizontal shafts to verify the linearity of wide-range turbine shaft runout sensors.
Iron, Steel and Metallurgy
Verifies bearing vibration sensors on blast furnace blowers, large exhaust fans, and rolling mill drive motors, withstanding the harsh environments of heavy vibration and high dust.
When using the 330186-02 shaft micrometer, securely fasten the magnetic base or straps to the machine casing or shaft to prevent displacement during testing, and ensure the shaft target surface is clean and free from severe wear.
Maintain a single direction of rotation during calibration to eliminate mechanical backlash, apply corresponding curve corrections to the proximitor output voltage if the actual shaft material is not standard 4140 steel, and strictly avoid live operation in hazardous areas.

Technical notes
Technical notes
The Bently Nevada 330186-02 is a 3300 XL series Metric Shaft Micrometer verification kit (0-25 mm range) compliant with the API 670 Standard. This instrument is engineered to mount the verification apparatus directly onto the physical shaft or machine casing of rotating equipment for in-situ proximity transducer system verification and loop testing. Its core assembly comprises an adjustable magnetic base, heavy-duty mounting straps, and a comprehensive set of metal probe collets (supporting 1/4 in, 3/8 in, 1/2 in, 5/8 in, as well as M8, M10, M14, and M16 threaded probes).
The 330186-02 is a 3300 XL series Shaft Micrometer manufactured by Bently Nevada, designed for verifying the output signals of eddy current proximity transducer systems directly on-site at the machine.
What is the primary application for the 330186-02?
It is primarily used to check the Proximitor Sensor's output signal when the proximity probe is viewing a rotating machinery rotor shaft or the piston rod of a reciprocating compressor.
What is the difference between the 330186-02 Shaft Micrometer and a benchtop micrometer?
hile a benchtop micrometer uses a built-in metal target button (such as AISI 4140), the 330186-02 Shaft Micrometer mounts directly onto the actual machine shaft or piston rod, utilizing the real machinery surface as the measurement target.
How does the 330186-02 operate to perform a test?
Rotating the micrometer head moves the probe precisely, comparing probe displacement with Proximitor voltage output.
What does the -02 suffix mean in 330186-02?
The "-02" suffix indicates that the micrometer utilizes metric scale units, typically covering a measurement range of 0 to 25 mm.
