Bently Nevada 330101-00-28-10-02-00 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-28-10-02-00 is an unarmored 8 mm proximity probe configured with a fully threaded 3/8-24 UNF housing (0.0 inches unthreaded length), a 2.8-inch case length, and a 1.0-meter (3.3 feet) standard coaxial cable with a miniature ClickLoc connector. Designed for systems that do not require hazardous area approvals, this specific variant provides non-contact vibration and shaft position measurements in industrial machinery. It acts as a critical sensing element within a 3300 XL monitoring chain, pairing seamlessly with a 330180 series Proximitor sensor and a corresponding standard extension cable to deliver highly accurate displacement readings.

This proximity probe utilizes eddy-current technology to track dynamic displacement, such as radial shaft vibration and axial thrust position. Since it is constructed without protective armor, this variant is ideal for installations where the cable path is adequately protected inside conduits or dry machine casings. Its 1.0-meter cable must be integrated into a 5-meter or 9-meter overall system configuration to maintain precise calibration and minimize interference.

Features

• 8 mm tip diameter proximity probe designed for non-contact eddy-current displacement measurement.
• Fully threaded 2.8-inch case length without protective armor, optimal for installations where external mechanical wear is not a primary risk.
• Equipped with a miniature coaxial ClickLoc connector, ensuring a secure, click-verified snap connection.
• Standard cable design suited for typical industrial environments with oil and moisture exposure.
• Robust stainless steel case construction with high-performance PPS tip material.

Applications

Typical applications for this probe include turbine shaft vibration and position monitoring, critical compressor and pump rotor displacement measurements, and general rotating machinery protection within power generation, oil and gas, and chemical processing facilities.

Installation Guidelines

To ensure proper operation of the proximity probe, verify that it is mounted with the correct probe gap (typically adjusted to -9 Vdc or approximately 1.27 mm / 50 mils) according to system calibration. Route the probe cable with proper shielding and grounding practices to eliminate noise coupling. Ensure that the thread engagement limits are respected during installation, and finger-tighten the ClickLoc connectors to prevent damage to the gold-plated contacts.
