Bently Nevada 330710-000-060-50-02-00 3300 XL 11 mm Proximity Probe

Description

330710-000-060-50-02-00 specifies an M16 x 1.5 metric threaded 3300 XL 11 mm proximity probe with integrated stainless steel armor. This configuration is defined by a 60 mm overall case length (Option 060) that is fully threaded with 0 mm unthreaded length (Option 000). The probe has a total length of 5.0 meters (Option 50) and is equipped with standard FEP triaxial cable terminated in a miniature coaxial ClickLoc connector (Option 02) with no agency approvals required (Option 00).

Operating as a non-contact eddy-current displacement sensor, this probe is part of the Bently Nevada 3300 XL 11 mm transducer system. The 11 mm tip diameter provides a linear range of 4.0 mm (160 mils), enabling measurements of axial shaft position, steam turbine differential expansion, or reciprocating compressor rod drop. The integrated flexible AISI 302 stainless steel armor with FEP outer jacket protects the triaxial cable from physical abrasion and mechanical damage in demanding industrial environments.

Features

• M16 x 1.5 metric threaded steel probe body with built-in flexible AISI 302 stainless steel armor and FEP outer jacket.
• Fully threaded 60 mm overall case length with 0 mm unthreaded section.
• 5.0 meters total probe length designed specifically for direct connection to a 5.0 meter system length Proximitor sensor.
• Miniature coaxial ClickLoc connector providing secure, click-locking connection to the system extension cable.
• Standard triaxial cable with 75 ohm impedance and fluoroethylene propylene (FEP) insulation.
• Polyphenylene sulfide (PPS) probe tip material designed to withstand high-temperature and chemical exposure.

Applications

This proximity probe is used within heavy industrial machinery protection and monitoring networks. Key applications include:

• Axial (thrust) shaft position measurements on large turbines and compressors.
• Ramp differential expansion measurements on industrial steam turbines.
• Rod position or rod drop monitoring on reciprocating compressors.
• Tachometer, phase reference (Keyphasor), and zero speed measurements on rotating shafts.

Installation Guidelines

To establish safe and accurate operation, the 3300 XL 11 mm proximity probe requires proper physical installation and electrical setup:

• Ensure the probe tip is free from proximity to adjacent metal structures other than the observed target shaft to avoid cross-talk or inaccurate calibration. The target surface should be a minimum of 30.5 mm (1.2 in) in diameter.
• Avoid over-torquing the probe during installation; do not exceed the maximum rated installation torque of 63.3 N-m (560 in-lb) for M16 x 1.5 cases. The recommended mounting torque is 21.1 N-m (187 in-lb).
• Maintain the minimum cable bend radius of 25.4 mm (1.0 in) when routing the armored lead.
• Verify the 5.0-meter probe is matched with a corresponding 5.0-meter Proximitor sensor and that the total system length (including any extension cable) matches the Proximitor's calibration requirement.
• Tighten ClickLoc coaxial connections to finger tight during final assembly.
