Bently Nevada 330709-000-050-10-02-05 3300 XL 11 mm Proximity Probe

Description

An unthreaded length of 0 mm (Option 000) and an overall case length of 50 mm (Option 050) define the metric M16 x 1.5 unarmored body configuration of this 330709-000-050-10-02-05 3300 XL 11 mm proximity probe. This metric non-contact transducer operates without stainless steel armor and is equipped with a 1.0 m (3.3 ft) integrated coaxial cable (Option 10) terminated in a standard miniature coaxial ClickLoc connector (Option 02) without a connector protector.

With an Option 05 configuration, this probe includes multiple international agency certifications for hazardous areas, allowing for direct installation in intrinsically safe and non-incendive environments. Designed to work in coordination with a 330730 extension cable and a 330780 Proximitor sensor, this transducer system offers a 4.0 mm (160 mils) linear range, which is approximately double that of the standard 8 mm transducer systems, making it highly effective for axial position, ramp differential expansion, and reciprocating compressor rod measurements.

Features

• Metric M16 x 1.5 threaded case with 0 mm unthreaded length and 50 mm total case length.
• Integrated 1.0 m (3.3 ft) triaxial FEP insulated standard cable without protective armor.
• Gold-plated brass miniature coaxial ClickLoc connector for reliable signal transmission.
• Generates a scale factor of 3.94 V/mm (100 mV/mil) over a 4.0 mm (160 mils) linear range.
• Multiple agency approvals (Option 05) including ATEX, IECEx, and CSA certifications for hazardous areas.

Applications

• Axial thrust position monitoring on steam and gas turbines.
• Ramp differential expansion measurements on power generation turbines.
• Reciprocating compressor rod position and rod drop monitoring.
• Shaft vibration and Keyphasor phase reference sensing on large rotating machinery.

Installation Guidelines

• Gap Adjustment: Adjust the sensor gap to 2.5 mm (100 mils) from the target surface, corresponding to a nominal output voltage of -10 Vdc.
• Minimum Bend Radius: Maintain a minimum coaxial cable bend radius of 25.4 mm (1.0 in) during installation to protect signal transmission.
• Torque Limit: Tighten the M16 x 1.5 probe case to a recommended 21.1 N-m (187 in-lb). Do not exceed the maximum rated torque of 63.3 N-m (560 in-lb) to prevent damage.
• Connector Connection: Screw ClickLoc connectors together hand-tight. Do not use mechanics tools that could over-torque the brass housing.
