Bently Nevada 330703-00-060-10-11-00 3300 XL 11 mm Proximity Probe

Description

Option 00 (0 mm unthreaded length), Option 060 (60 mm overall case length), and Option 11 (ClickLoc connector with connector protector, FluidLoc cable) specify this standard metric 3300 XL 11 mm Proximity Probe configuration — 330703-00-060-10-11-00. This non-contact eddy-current displacement probe has an M14 x 1.5 metric thread and does not feature stainless steel armor. It is used in 3300 XL 11 mm Proximity Transducer Systems for shaft vibration, axial position, and Keyphasor measurements on rotating machinery such as steam turbines, gas turbines, and compressors.

This specific configuration incorporates a FluidLoc cable (Option 11) to prevent oil or other fluids from leaking along the internal cable conductor or jacket. It has a pre-installed fluorosilicone connector protector at the ClickLoc coaxial connector interface to seal against moisture and environmental contaminants. With a total length of 1.0 meter (Option 10), this probe does not require agency approval certifications (Option 00) and is designed to interface with a 3300 XL 11 mm extension cable and Proximitor sensor for a complete 5-meter or 9-meter transducer system.

Features

• M14 x 1.5 metric thread case configuration without protective armor (base model 330703)
• 0 mm unthreaded length (Option 00) and 60 mm overall case length (Option 060)
• 1.0 meter total probe length (Option 10)
• FluidLoc coaxial cable (Option 11) to seal against fluid leakage along the inner conductors
• ClickLoc coaxial connector with integrated fluorosilicone connector protector (Option 11)
• 4.0 mm (160 mils) linear range for high-accuracy measurement of shaft vibration and axial position
• Standard scale factor (ISF) of 3.94 V/mm (100 mV/mil) for precise signal reproduction

Applications

• Turbine and compressor shaft vibration monitoring
• Axial (thrust) position measurements on steam turbines
• Rod position and rod drop monitoring on reciprocating compressors
• Tachometer, zero speed, and Keyphasor phase reference signal generation
• Fluid film bearing machine monitoring where a wider linear range than 8 mm probes is required

Installation Guidelines

Observe the minimum bend radius of 25.4 mm (1.0 in) for the coaxial cable during installation to avoid signal attenuation or inner core fracture. Tighten the M14 x 1.5 probe case to the recommended installation torque of 21.1 N-m (187 in-lb); do not exceed the maximum limit of 63.3 N-m (560 in-lb) to prevent thread strip-out or structural failure of the probe casing. The pre-installed fluorosilicone connector protector must be properly positioned over the probe-to-extension-cable coaxial mating interface to ensure an environmental seal against oil, water, and atmospheric contaminants.
