Description

Bently Nevada 330101-00-30-50-02-00 3300 XL 8mm Proximity Sensor

The Bently Nevada 330101-00-30-50-02-00 is a high-precision eddy current sensor engineered for the non-contact measurement of radial vibration and axial shaft position. As a foundational component of the 3300 XL 8mm Transducer System, this probe provides a consistent 200 mV/mil (7.87 V/mm) output when paired with a matching Proximitor. It is specifically designed to monitor critical rotating machinery, such as high-speed turbines and centrifugal compressors, where accurate displacement data is essential for asset protection.

Enhanced Measurement Accuracy for Industrial Assets

This transducer configuration is optimized for installations requiring specific reach and cable management. Specifically, the 330101-00-30-50-02-00 features a 3.0-inch threaded case length and a 5.0-meter integral cable, allowing for extended reach in deep-casing applications without the need for an immediate extension cable connection. Furthermore, it is factory-calibrated for AISI 4140 steel targets, ensuring linear performance across an 80-mil (2.0 mm) sensing range. As a result, maintenance engineers can achieve repeatable and reliable vibration data under a wide variety of machine load conditions.

Technical Specification Matrix

Resilience in Hazardous and High-Temperature Zones

The 330101-00-30-50-02-00 is built to maintain signal integrity in the most aggressive process environments. Moreover, the probe tip is constructed from high-grade polyphenylene sulfide (PPS), which creates a hermetic seal against pressurized lubricants, steam, and corrosive chemical vapors. In addition, the 5.0-meter integral cable is FEP-insulated, providing excellent mechanical flexibility and thermal resistance. Therefore, this probe is the preferred choice for reliability professionals who require long-term sensor stability in hazardous area classifications and high-temperature machinery housings.

FAQ

What are the advantages of the 5.0-meter integral cable option?

The 5.0-meter cable allows the probe to connect directly to a Proximitor in a 5-meter system without using an extension cable. Specifically, this reduces the number of connection points, which can lower the risk of signal interference and oil ingress in the field.

Is this probe compatible with a 9-meter 3300 XL system?

Yes, but only if it is paired with a 4.0-meter extension cable. Furthermore, you must verify that the 3300 XL Proximitor sensor is calibrated for a total electrical length of 9.0 meters to ensure the scale factor remains accurate.

How does the “02” approval code benefit my facility?

The 02 code provides multi-agency certification, making the probe compliant with safety standards across various global jurisdictions. Accordingly, this ensures the sensor is rated for intrinsically safe installation in explosive or flammable atmospheres when used with the appropriate barriers.

Can this 8mm probe be used on shafts with a diameter smaller than 3 inches?

While technically possible, a smaller shaft diameter may cause “cross-talk” or side-view interference. Ultimately, for shafts with very small diameters, the 3300 XL NSv (Near Surface version) or a smaller diameter probe may be more appropriate to maintain linearity.
