Bently Nevada 330902-00-40-10-02-CN 3300 NSv Proximity Probe

Description

330902-00-40-10-02-CN is an armored 3300 NSv proximity probe with a 1/4-28 UNF thread. It is designed for non-contacting vibration and position measurements where installation clearance is limited.

The probe operates as part of the 3300 XL NSv Proximity Transducer System. A complete system consists of a 3300 NSv probe, a compatible extension cable, and a 3300 XL NSv Proximitor Sensor.

This configuration has a 0.0 in unthreaded length, a 4.0 in overall case length, and a 1.0 m total length. It includes stainless steel armor, a standard FEP-insulated coaxial cable, and a miniature coaxial ClickLoc connector.

The NSv design supports applications where counterbore, side-view, rear-view, or target-size restrictions limit the use of standard 5 mm and 8 mm proximity probes.

Features

• Armored standard-mount probe construction
• Suitable for restricted-clearance installations
• Improved side-view characteristics for small shafts and targets
• Gold-plated brass ClickLoc connector
• TipLoc probe-tip molding construction
• CableLoc probe cable attachment
• Increased chemical resistance for process compressor applications
• Compatible with 3300 NSv extension cables
• Compatible with 3300 XL NSv Proximitor Sensors

Applications

• Centrifugal air compressors

Installation Guidelines

• Install the probe in a correctly tapped 1/4-28 mounting hole.
• Use a number 3 or larger tap drill when preparing the mounting hole.
• Do not exceed 0.375 in of thread engagement.
• Apply 5.1 N*m recommended installation torque.
• Do not exceed the maximum torque of 7.3 N*m.
• Maintain a minimum cable bend radius of 25.4 mm.
• Set the initial probe gap to 1.0 mm when used in a complete NSv system.
• Select the extension cable so the combined system length equals 5 or 7 m.
• Protect the ClickLoc connection from oil, moisture, and contamination.
• Use a connector protector or approved silicone tape where required.
• Maintain at least 25 mm tip separation for parallel axial measurements.
• Maintain at least 23 mm tip separation for radial X-Y measurements.
• Avoid sustained probe exposure below -34 degC to protect the pressure seal.
• Verify that process liquids and gases remain safely contained if probe leakage occurs.
