Description

Bently Nevada 330101-37-57-10-02-05 3300 XL 8mm Proximity Sensor

The Bently Nevada 330101-37-57-10-02-05 is a high-precision eddy current proximity probe engineered for the non-contact measurement of radial vibration and axial position. As a primary sensor in the 3300 XL 8mm Transducer System, it provides a consistent linear output of 200 mV/mil (7.87 V/mm) when integrated with a matching Proximitor. This specific configuration is designed to offer specialized reach and connection lengths for critical assets in power generation, oil and gas, and heavy manufacturing sectors.

Precision Engineering for Machinery Protection

This proximity probe facilitates advanced predictive maintenance by detecting microscopic changes in shaft behavior. Specifically, the 330101-37-57-10-02-05 features a 3.7-inch threaded case length and a 5.7-inch unthreaded section, making it ideal for deep-housing installations where the probe must pass through internal machine walls. Furthermore, the 1.0-meter (approx. 3.3 feet) integral cable is equipped with gold-plated ClickLoc miniature coaxial connectors, ensuring a high-integrity signal path to the system’s extension cable. As a result, operators receive real-time data to prevent catastrophic failures in turbines, compressors, and pumps.

FAQ

What is the benefit of the 02 agency approval option?

The 02 option provides multi-agency certification, including ATEX, IECEx, and North American approvals. Specifically, this allows the probe to be utilized globally in intrinsically safe applications and hazardous atmospheres without requiring separate regional parts.

Can this probe be used in a 5-meter or 9-meter system?

Yes, the 1.0-meter integral cable version is compatible with both 5-meter and 9-meter 3300 XL systems. Furthermore, you must ensure that the extension cable and Proximitor are selected to match the desired total electrical length for accurate calibration.

How does the PPS tip protect the sensor?

The PPS (Polyphenylene Sulfide) tip is molded to the probe lead, creating a liquid-tight seal. Accordingly, this prevents oil or other contaminants from wicking through the probe to the connector, ensuring long-term signal stability even in high-pressure environments.

Is this probe compatible with older 3300 series monitors?

While the 3300 XL series is backward compatible with most non-XL 3300 systems, the scale factor must be verified. Ultimately, the 330101-37-57-10-02-05 is optimized for use with the 3300 XL Proximitor to achieve the best linearity and temperature stability.
