Bently Nevada 330910-01-08-10-01-05 3300 NSv Probe Proksimit

Description

330910-01-08-10-01-05 specifies this 3300 NSv proximity probe configuration featuring an M10x1 metric thread with stainless steel armor, a 10 mm unthreaded length, an 80 mm case length, a 1.0 m total length, a ClickLoc connector with protector, and multiple agency approvals. This transducer component is used for non-contact shaft vibration and axial position measurement on high-speed equipment where mounting clearance is tightly constrained and a reduced target area is present.

This configuration incorporates flexible stainless steel armor to provide physical protection for the FEP-insulated coaxial cable in demanding machine casings, contrasting with unarmored configurations such as the 330905 probe. The inclusion of a pre-installed fluorosilicone connector protector (Option 01) seals the miniature coaxial ClickLoc connection against turbine oil, humidity, and atmospheric particulate ingress, differentiating it from standard non-protected configurations (Option 02).

Features

• Option 01 unthreaded length: Identifies a 10 mm unthreaded probe case length.
• Option 08 case length: Provides an 80 mm overall metric case length with M10x1 threads.
• Option 10 total length: Configured with a 1.0 m (39 inches) FEP-insulated coaxial probe lead.
• Option 01 connector: Features a miniature male coaxial ClickLoc connector with a pre-installed protective sleeve.
• Option 05 agency approval: Certified with multiple hazardous area approvals for zone-classified environments.
• Stainless steel armor: Features flexible AISI 302 stainless steel armor for protection against physical wear and abrasion.

Applications

This proximity probe is used in the following industrial scenarios:

• Radial vibration and axial position measurements on small shaft diameters under 20 mm (0.8 in).
• Vibration monitoring on high-speed turbomachinery and aeroderivative gas turbines.
• Small-bore machinery and process compressors with restricted internal mounting clearance.
• Hazardous-area rotating machinery installations requiring certified, armored instrumentation.

Installation Guidelines

• The maximum thread engagement length for M10x1 probe threads is 15 mm. Thread engagement exceeding this limit may result in binding during installation.
• Mount the probe case using the recommended torque of 11.3 N m (100 in lb), ensuring that the torque does not exceed the maximum rated limit of 33.9 N m (300 in lb).
• Ensure the armored cable lead is routed with a bend radius of at least 25.4 mm (1.0 in) to prevent internal conductor damage.
• Verify that the total combined length of this 1.0 m probe and the mating extension cable equals the required system length of the calibrated 3300 XL NSv Proximitor (typically 5.0 m or 7.0 m).
• Utilize the pre-installed fluorosilicone connector protector to completely seal the connection interface against industrial fluids and machine oils.
