Bently Nevada 330103-00-02-10-02-05 3300 XL 8 mm Proximity Probe

Description

Fully threaded M10 x 1 metric probe body (Option 00) with a 20 mm overall case length (Option 02) and a 1.0 m total length (Option 10) defines the specific mechanical configuration of the 330103-00-02-10-02-05 3300 XL 8 mm proximity probe.

Unlike variants with standard 3/8-24 UNF threads (such as the 330101 series), this probe features metric M10 x 1 threads and is designed without protective armor (unarmored standard FEP cable). The configuration is equipped with a miniature coaxial ClickLoc connector (Option 02) without a connector protector and is certified with CSA, ATEX, and IECEx hazardous area approvals (Option 05) for operation in Zone 0, 1, and 2 environments. The probe works as part of a complete 3300 XL system, providing a voltage output proportional to the gap distance between the probe tip and target surface to track shaft vibration and axial position.

Features

• M10 x 1 metric thread configuration for direct installation in metric-threaded machine casings.
• 0 mm unthreaded length (Option 00) provides a fully threaded casing for maximum mounting depth flexibility.
• 20 mm overall case length (Option 02) designed for compact spaces and low-profile installation depths.
• 1.0 m total length (Option 10) unarmored coaxial cable terminates in a miniature male ClickLoc connector.
• Option 05 approvals package certifies the probe for ATEX, IECEx, and CSA hazardous area classifications.

Applications

• Eddy-current fluid-film bearing vibration measurements on rotating machinery.
• Shaft axial position and radial displacement tracking in steam turbines, gas turbines, and compressors.
• Speed and Keyphasor reference measurements in industrial power plants and petrochemical facilities.

Connections and Interfaces

The probe lead terminates in a miniature male coaxial ClickLoc connector. Below is the electrical termination path:

Installation Guidelines

• Set initial probe gap using dc voltage (typically -10 Vdc corresponds to a nominal 1.27 mm or 50 mil gap for standard calibration).
• Observe minimum cable bend radius of 25.4 mm (1.0 inch).
• Tighten the probe case to recommended torque limits: maximum case torque is 22.6 N-m (200 in-lb); recommended first-three-threads installation torque is 7.5 N-m (66 in-lb).
• Use safety wire holes in the lock nuts to secure the probe position.
• Avoid laying cables near high-voltage wiring to minimize electrical noise interference.

Compliance and Certifications

The Option 05 agency approval package certifies this probe for use in hazardous areas with the following standard registrations:

• CSA: Class I, Zone 0, 1, 2; Groups A, B, C, D; Ex ia IIC
• ATEX: II 1 G, Ex ia IIC T4/T5 Ga
• IECEx: Ex ia IIC T4/T5 Ga
• CE Mark: Complies with applicable European directives for electromagnetic compatibility and hazardous area safety
