Description

The Bently Nevada 330901-00-90-10-02-CN is a 3300 NSv (Non-Standard vibration) proximity probe designed for high-precision vibration and position monitoring in space-constrained industrial environments. This probe utilizes eddy current technology to provide accurate measurements in applications where standard 5 mm or 8 mm probes are physically restricted by counter-bore, side-view, or rear-view limitations.

Features

• Designed for tight installation requirements where standard transducer systems cannot fit.
• Average scale factor of 7.87 V/mm (200 mV/mil).
• Compatible with 3300 NSv Proximitor sensors for high-precision signal conditioning.
• Features ClickLoc connectors for secure, reliable cable termination.
• Suitable for small target applications, including shafts smaller than 51 mm (2 in).

Applications

• Radial vibration and radial position monitoring for fluid-filmed bearing machines.
• Axial (thrust) position measurements on flat targets.
• Tachometer and zero-speed detection.
• Phase reference (Keyphasor) signal generation.

Technical Specifications

Installation Guidelines

• Handling: Use care when handling the probe tip to avoid damage to the sensing element.
• Connection: The probe utilizes ClickLoc connectors. Tighten these by hand only; the use of pliers or tools may damage the connector housing.
• Field Wiring: Use three-conductor shielded triad cable (16 to 24 AWG). Ensure the total distance between the Proximitor sensor and the monitor does not exceed 305 meters (1,000 feet).
• Grounding: Ensure proper system grounding to prevent electrostatic buildup, particularly in hazardous area installations.
• Environment: Verify that the installation area is free from excessive mechanical stress on the cable assembly.

FAQ

What does the NSv designation mean?

NSv stands for Non-Standard vibration. These probes are specifically engineered for smaller machinery or tight spaces where standard 3300 XL 8 mm probes are too large to be installed effectively.

Can this probe be used for axial position measurement?

Yes, it is ideal for axial (thrust) position measurements on flat targets as small as 15 mm (0.6 in).

What is the primary benefit of the ClickLoc connector?

The ClickLoc connector provides a secure, vibration-resistant connection that simplifies installation and ensures signal integrity without the need for specialized crimping tools.
