Bently Nevada 330901-00-90-05-02-00

Product Overview

The Bently Nevada 330901-00-90-05-02-00 is a core component of the 3300 XL NSv proximity sensor system. 3300 XL NSv Proximity probe is a standard-mount, unarmored eddy-current probe designed for high-precision vibration and position measurement on rotating machinery where space is extremely limited. It fully integrates the probe, extension cable, and proximity sensor into a reliable monitoring system, ideal for compact equipment where standard 5 mm and 8 mm sensor systems cannot fit.

Product Features

The probe head and housing are designed for simple installation in counterbores, side-viewing areas, or tight spaces behind equipment. This makes it a good choice for measuring in small or hard-to-reach places.

The patented TipLoc process ensures a strong bond between the probe tip and the housing.

The patented CableLoc design offers a pull-out strength of up to 220 N (50 lbs), helping prevent the cable from coming loose.

The gold-plated brass ClickLoc connector has a locking feature that prevents it from loosening due to vibration and ensures good electrical contact.

Compared to earlier models, the 3300 NSv probe housing material is more resistant to chemicals. This makes it suitable for use in tough process compressor environments.

330901-00-90-05-02-00 can work reliably in very cold or hot temperatures, from -52°C to +177°C. This allows use in tough industrial conditions.

This model (330901-00-90-05-02-00) comes with a 1/4-28 UNF thread, a 9-inch body, a 0.5-meter overall length, and includes a standard cable and ClickLoc connector. No extra assembly is needed.

Applications

Bently Nevda Proximity probe system is widely used for condition monitoring of the following rotating machinery: Centrifugal air compressors, refrigeration compressors, process gas compressors, small water pumps, motors, and fans. Also used in Radial Vibration Measurement, Axial (Thrust) Position Measurement, Keyphasor Reference Signal,Zero Speed Detection.

Compatibility and Interchangeability

330901 probe is mechanically and interchangeable with the probes and extension cables of Bently Nevada's previous 3300 RAM systems. When upgrading from a 3300 RAM system to a 3300 XL NSv system, the existing probe and extension cable can continue to be used.

When upgrading from earlier 3000 or 7000 Series I90 sensor systems, 330901 probe, extension cable, and proximity sensor must be replaced with the NSv components.

Bently Nevada 330901-00-90-05-02-00 be used with the specified 3300 NSv extension cable and 3300 XL NSv proximity sensor to form a complete and fully functional measurement system.

Performance Impact

For radial vibration measurements, the recommended minimum shaft diameter is 30 mm. Measuring on smaller shaft diameters can cause the average scale factor to vary by more than 10%.

For the probe axial position measurements, the target plane diameter should be at least 8.9 mm, and 13 mm or greater is recommended. The other side, the scale factor will be affected.

The recommended minimum countersunk diameter is 13 mm. A value smaller than this will alter the system scale factor at high clearances.

Bently Nevada 330901-00-90-05-02-00 has a 1.5 mm linear range, starting approximately 0.25 mm in front of the target. The recommended gap setting is 1.0 mm to ensure the output signal is within the optimal linear range.
