The 330185-02 is a 3300 XL series Metric Precision Micrometer Verification Kit with a measurement range of 0-25 mm. Compliant with the API 670 Standard, this instrument is utilized for performance verification, acceptance testing, and calibration of proximity transducer systems in both laboratory and field environments. By moving a high-precision 4140 target button in precise metric increments to simulate physical shaft movement, it allows the evaluation of the proximitor sensor's voltage output against engineering specifications for linear range, average scale factor (ASF), and incremental scale factor (ISF).
Validates key transducer system characteristics efficiently
Engineered to support testing in strict accordance with industry standards
Features a compact footprint, making it ideal for laboratory or workshop workbenches
The 330185-02 is utilized for performing acceptance testing on transducer systems to the transducer's performance specifications or to the American Petroleum Institute's Standard API 670. Bently Nevada transducer systems are all manufactured to meet published performance specifications. They have a specified linear range, average scale factor (ASF), and incremental scale factor (ISF). Transducer systems have maximum deviation from straight line (DSL) and ISF tolerances, both at ambient temperatures and for extended temperatures.
The 330185-02 Precision Micrometer supports the verification of whether the transducer system is working properly and within published specifications. This precision micrometer checks the transducer system. A probe mounting adapter holds the probe while a high-precision 4140 target button is moved toward or away from the probe tip in specific metric increments.
This target button simulates the position of the shaft. The output from the Proximitor Sensor is recorded using a voltmeter. The operating condition of the transducer system is verified by comparing a newly generated probe curve using the 330185-02 Precision Micrometer with published specifications for that transducer system. It is also used to check and verify the proper operation of shaft position monitors.

When using the 330185-02 micrometer, maintain a clean 4140 steel target surface free from demagnetization or pitting, and rotate the micrometer in a uniform, single direction during calibration to eliminate mechanical backlash. Utilize the correct probe sleeve matching the probe diameter to prevent eccentricity, and avoid live operation in hazardous areas to ensure instrument loop safety.

Technical notes
Technical notes
Maintaining the Bently Nevada 330185-02’s Average Scale Factor (ASF) within its ±0.6% tolerance requires the supplied AISI 4140 alloy steel target button. For accurate calibration curves that match factory datasheets, testing must be conducted at a controlled room temperature of 22±3°C (72±5°F).
The 330185-02 works with all 3300 XL proximity probe systems. It also supports earlier Bently Nevada Proximitor sensor models.
How often should I calibrate the 330185-02?
Bently Nevada recommends annual calibration for the 330185-02. For proper traceable calibration, send it to an accredited laboratory.
What is the difference between 330185-01 and 330185-02?
The 330185-02 is the metric version with 0-25 mm range. It offers 0.0005 mm resolution. In contrast, the -01 version uses imperial units (0-1 inch range).
Can the 330185-02 test high-temperature transducer systems?
Yes, the 330185-02 supports extended temperature testing. For such tests, you must place the entire micrometer in an environmental chamber.
What transducer parameters can the 330185-02 verify?
It can verify multiple critical parameters of a transducer system, including linear range, incremental gain, Deviation from Best Fit Straight Line (DSL), and Average Scale Factor (ASF).
