Bently Nevada 330104-02-19-10-01-00 3300 XL 8 mm Armored Proximity Probe

Description

Option 02 (20 mm unthreaded length) and Option 19 (190 mm case length) specify this 3300 XL 8 mm proximity probe configuration — 330104-02-19-10-01-00. This eddy-current probe features M10 x 1 metric threads and an integrated stainless steel armor sleeve to protect the lead cable in challenging mechanical environments. The system delivers a voltage output proportional to the gap between the probe tip and the observed target surface, allowing static and dynamic measurements of shaft position and vibration.

Unlike configurations that omit mechanical protection, the armored casing on this variant guards the coaxial cable from physical abrasion, pinching, and fluid exposure. With a total length of 1.0 meter and standard cable material, it connects to a standard 3300 XL extension cable and Proximitor sensor to form a complete 5-meter or 9-meter transducer loop. This configuration is ordered with a miniature coaxial ClickLoc connector and a pre-installed connector protector (Option 01) but without hazardous area agency approvals (Option 00).

Features

• M10 x 1 metric threads with integrated stainless steel armor protection on the coaxial cable.
• Option 02 specifies a 20 mm unthreaded body length to accommodate specific mounting bracket depths.
• Option 19 provides an extended 190 mm overall case length for deep-reach installation requirements.
• Option 10 total length of 1.0 meter (3.3 feet) matches standard transducer system layout practices.
• Option 01 ClickLoc coaxial connector comes with a pre-installed fluorosilicone connector protector.
• PPS plastic probe tip is chemically resistant to turbine oils and industrial solvents.

Applications

• Machinery protection systems monitoring fluid-film bearing machines.
• Shaft radial vibration and axial position measurement on industrial turbines, compressors, and pumps.
• Keyphasor reference and rotational speed monitoring on metric-threaded machinery.
• Heavy industrial machinery installations requiring robust armored physical cable protection.

Installation Guidelines

• Always maintain a minimum thread engagement of 15 mm into the metric mounting bracket.
• Ensure the unthreaded length (20 mm) matches the application casing clearance to avoid probe tip damage.
• Route the armored cable using standard industrial conduits or cable trays, respecting a minimum bend radius of 25 mm.
• Use only the recommended gold-plated ClickLoc connector tools during final connector assembly to ensure finger-tight electrical contact.
• Isolate the probe case electrically from any nearby high-voltage sources; the 3300 XL Proximitor sensor housing provides baseline isolation.
