Description

The Bently Nevada 330101-02-21-10-01-00 is an unarmored 8 mm proximity probe engineered for high-precision, non-contact machinery protection and condition monitoring. This specific configuration features a 3/8-24 UNF thread with a short unthreaded case length of 0.2 inches (option 02) and an overall case length of 2.1 inches (option 21). Fitted with a 1.0 meter standard coaxial cable (option 10) and a miniature coaxial ClickLoc connector with an integrated connector protector (option 01), this sensor does not require agency approvals (option 00) and is optimized for standard industrial vibration chains. Operating on the eddy-current measurement principle, this probe determines the precise dynamic and static distance between the probe tip and a target conductive shaft. It is part of the 3300 XL 8 mm Transducer System, pairing with a 3300 XL extension cable and a 330180 series Proximitor sensor. Together, this chain generates a highly stable voltage output proportional to shaft vibration and position, feeding critical real-time diagnostic data to Bently Nevada 3500 rack modules or other machinery protection systems.

Features

Proximity tip diameter of 8 mm designed for precise non-contact eddy-current displacement measurements.
Integrated connector protector (option 01) safeguarding the miniature ClickLoc coaxial connection against oil, moisture, and contaminants.
Unarmored stainless steel threaded body (3/8-24 UNF) designed for bearing housing or machine casing mount.
Compact 0.2 in unthreaded length and 2.1 in case length for tight mechanical clearance installations.
1.0 meter total cable length (standard coaxial) suited for neat connection to local junction boxes.
Excellent thermal performance and mechanical durability across harsh industrial rotating environments.

Applications

The Bently Nevada 330101-02-21-10-01-00 probe is ideal for permanent mounting on critical rotating machinery, including:

Steam and gas turbine shaft vibration and axial position measurement.
Rotor dynamic displacement monitoring in large compressors and industrial pumps.
Bearing oil film clearance and thickness monitoring.
Radial vibration, thrust position, and speed sensing on high-speed rotating shafts.

Installation Guidelines

Ensure reliable transducer system performance by adhering to the following engineering guidelines:

Probe Gap Calibration: Mount the probe with the correct initial mechanical gap (typically 1.27 mm or 50 mils) to target the midpoint of the Proximitor sensor's calibrated linear voltage range.
Thread Integrity: Use care when threading the probe into brackets or casings. Do not exceed recommended tightening torque to prevent thread damage.
Cable Protection: Route the standard unarmored coaxial cable inside rigid or flexible conduit to protect it from mechanical wear, pinching, and high temperatures.
Connector Protection: Verify that the integrated connector protector is properly seated to insulate the ClickLoc junction from lubricating oil, moisture, and debris.
Grounding and Shielding: Properly terminate cable shields at the instrument/monitor end of the loop only, preventing ground loops that introduce electronic noise.

Product Documentation

Technical Datasheet (PDF) Complete specifications and technical drawings.

What does option 01 represent in the 330101-02-21-10-01-00 model number?

Option 01 indicates that this probe features a miniature coaxial ClickLoc connector paired with an integrated connector protector designed for standard coaxial cable.

What are the unthreaded and overall case length dimensions of this probe?

This configuration has an unthreaded length of 0.2 inches (option 02) and an overall threaded case length of 2.1 inches (option 21) with a 3/8-24 UNF thread structure.

Is this proximity probe armored or unarmored?

The base model 330101 is an unarmored proximity probe. If your installation requires rugged flexible steel armoring, you should look at the 330102 probe family instead.

What is the total length of this sensor, and which Proximitor does it pair with?

The probe has a total length of 1.0 meter (approx. 3.3 feet), denoted by option 10. It is designed to work as part of a 3300 XL 8 mm system when matched with a 3300 XL Proximitor sensor calibrated to the correct loop length.
