Bently Nevada 330709-000-030-10-02-00 3300 XL 11 mm Proximity Probe

Description

Metric M16 x 1.5 threaded probe case without armor (330709 base) with 0 mm unthreaded length (Option 000), 30 mm case length (Option 030), and 1.0 m total length (Option 10) specifies this 3300 XL 11 mm proximity probe configuration — 330709-000-030-10-02-00. This non-contact eddy-current displacement probe is used in 3300 XL 11 mm monitoring chains to measure shaft vibration and axial position on critical rotating machinery. It operates with a 3.94 V/mm (100 mV/mil) output scale factor when paired with a matching 3300 XL 11 mm Proximitor Sensor and extension cable.

This variant features a standard triaxial cable without physical armor casing and is equipped with a miniature coaxial ClickLoc connector at the cable termination (Option 02) without a connector protector. Unlike armored options (such as the 330710 series), this unarmored configuration is suited for installations inside conduit or protective enclosures where direct mechanical abrasion protection is not required. The M16 x 1.5 metric body threads provide secure standard mounting directly into machine cases or brackets.

Features

• M16 x 1.5 metric thread without mechanical protective armor.
• 0 mm unthreaded length (fully threaded case) with 30 mm overall case length.
• 1.0 meter (3.3 feet) integrated FEP triaxial probe cable length.
• Gold-plated brass ClickLoc miniature coaxial connector without connector protector.
• Patented TipLoc molding for robust bonding between probe tip and case.
• Patented CableLoc design provides 330 N (75 lb) pull strength between probe case and lead.

Applications

• Turbine and compressor shaft radial vibration measurement on 11 mm systems.
• Thrust position and axial rotor displacement monitoring.
• Industrial rotating machinery protection on large steam/gas turbines, generators, and large pumps.
• Standard-mount metric installations inside machine housings or enclosures.

Installation Guidelines

• Probe Gap Setting: Recommended physical gap is 2.5 mm (100 mils) from the target surface, corresponding to a nominal output of approximately -9 Vdc.
• Mounting Torque: Do not exceed the maximum rated torque of 63.3 N-m (560 in-lb) during probe case installation. Tighten to the recommended 21.1 N-m (187 in-lb) torque.
• Minimum Target Size: For calibrated accuracy, the flat target surface must have a minimum diameter of 30.5 mm (1.2 in). For shafts, the recommended minimum diameter is 152 mm (6.0 in).
• Thread Engagement: Maximum length of thread engagement is 24 mm to prevent mechanical binding during installation.
• Cable Protection: Keep the minimum cable bend radius above 25.4 mm (1.0 in). Run cables through standard conduit or trays to prevent environmental or physical damage.
