Description

The Bently Nevada 330907-05-30-05-02-05 is a 3300 NSv (Narrow Side View) Reverse Mount Proximity Probe designed for high-precision vibration and position monitoring in constrained environments. This transducer system is engineered for applications where standard 3300 XL 5 mm and 8 mm systems cannot be utilized due to counterbore, sideview, or rearview restrictions. It serves as an advanced replacement for legacy 3300 RAM, 3000-series, and 7000-series 190 transducer systems.

Features

• Designed for tight installation requirements with enhanced side-view characteristics.
• Average Scale Factor of 7.87 V/mm (200 mV/mil).
• Features patented TipLoc molding for a robust bond between probe tip and body.
• Equipped with gold-plated brass ClickLoc connectors to prevent loosening and ensure signal integrity.
• CableLoc design provides 220 N (50 lb) of pull strength.
• M10 x 1 metric probe thread configuration.

Applications

• Centrifugal Air Compressors: Ideal for internal high-speed shafts where space is limited.
• Refrigeration Compressors: Suitable for large-scale industrial chilling and HVAC systems.
• Process Gas Compressors: Offers superior chemical resistance compared to older RAM models.
• Small Hydrodynamic Bearing Machines: Enables precise radial and axial monitoring on small-diameter fluid-film bearings.

Technical Specifications

Installation Guidelines

• Ensure the probe is mounted in a counterbore of at least 13 mm (0.5 in) to avoid signal interference.
• Recommended torque for M10 x 1 probe cases is 11.3 N-m (100 in-lb); do not exceed 33.9 N-m (300 in-lb).
• Use connector protectors on all probe-to-extension cable and cable-to-Proximitor connections to prevent liquid ingress.
• Always power down the monitoring system before connecting or disconnecting transducer components to prevent electrical damage.
• Handle with care to avoid damaging the probe tip or kinking the coaxial cable.

FAQs

What is the 330907-05-30-05-02-05?

The Bently Nevada 330907-05-30-05-02-05 is a 3300 NSv Reverse Mount Probe designed for measuring radial vibration and axial position, often in small shaft, high-speed compressors.

What is the function of this probe?

It is a reverse mount proximity probe for measuring dynamic and static displacements, specifically optimized for small-target applications and hydrodynamic bearing machinery.

Is this probe chemically resistant?

Yes, the 3300 NSv probe offers greater chemical resistance to turbine oils and industrial lubricants compared to the older 3300 RAM probe.

What is the difference between this and the 3300 RAM probe?

The 3300 NSv provides improved side-view characteristics, allowing accurate measurement at closer distances to the probe target, making it ideal for small machinery where standard probes cannot fit.
