Bently Nevada 330703-000-080-10-02-00 3300 XL 11 mm Proximity Probe

Description

330703-000-080-10-02-00: 3300 XL 11 mm proximity probe featuring an M14 x 1.5 metric thread without armor, configured with 0 mm unthreaded length (Option 000), 80 mm overall case length (Option 080), 1.0 m total length (Option 10), miniature ClickLoc coaxial connector (Option 02), and no agency approvals required (Option 00).

Unlike armored versions or variants with integrated connector protectors, this configuration is supplied with an unarmored triaxial cable and a standard miniature coaxial ClickLoc connector. The 11 mm tip diameter provides a wider linear range than standard 8 mm systems, making this probe suitable for displacement and vibration monitoring on turbine and compressor shafts.

Features

• Thread Interface: Metric M14 x 1.5 thread, without armor (base model 330703).
• Mechanical Construction: Fully threaded case with 0 mm unthreaded length (Option 000) and an 80 mm case length (Option 080).
• Cable Length: 1.0 meter (3.3 feet) total cable length (Option 10) for compact installation configurations.
• Connector Options: Standard miniature coaxial ClickLoc connector (Option 02) without a connector protector.
• System Compatibility: Operates as part of a 3300 XL 11 mm proximity transducer system, connecting to a 3300 XL 11 mm extension cable and Proximitor sensor.

Applications

• Axial shaft position measurements on steam turbines and utility compressors.
• Ramp differential expansion measurements on industrial turbomachinery.
• Rod position or rod drop monitoring on reciprocating compressors.
• Tachometer speed and zero-speed measurements.
• Phase reference (Keyphasor) signal generation for machine vibration analysis.

Installation Guidelines

Ensure correct thread engagement with the machine housing or mounting bracket. For M14 x 1.5 threads, the recommended installation torque is 21.1 N-m (187 in-lb), with a maximum rated torque of 63.3 N-m (560 in-lb). The cable must maintain a minimum bend radius of 25.4 mm (1.0 in). Take precautions to protect the coaxial connector from moisture, dirt, and mechanical stress. Using silicon tape on the connection is not recommended where exposure to turbine oil is expected. Ensure the physical gap is adjusted to approximately 2.5 mm (100 mils) to align the measurement within the linear center of the transducer output range.

Compliance and Certifications

• CE Mark: Complies with European Community Directives (EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU).
• EMC Standards: EN 61000-6-2 (Immunity) and EN 61000-6-4 (Emissions) for industrial environments.
• Agency Approvals: No specialized hazardous area certifications required for this configuration (Option 00).
