Bently Nevada 330104-00-20-15-12-05 3300 XL Vibration Sensor

Product Overview

The 330104-00-20-15-12-05 is a high-precision 3300 XL 8mm proximity probe engineered by Bently Nevada for critical machinery protection. This eddy current sensor provides non-contacting displacement measurements, primarily used to monitor shaft radial vibration and axial thrust position. As a part of the 3300 XL series, the 330104-00-20-15-12-05 ensures compatibility with API 670 standards, delivering a linear scale factor of 7.87 V/mm (200 mV/mil) when integrated into a calibrated transducer system. This specific configuration features a FluidLoc cable and miniature coaxial ClickLoc connector, designed to maintain signal integrity in environments where fluid migration through the cable is a concern.

Engineering Advantages and Applications

The 330104-00-20-15-12-05 is frequently deployed on high-speed centrifugal compressors, steam turbines, and large pumps. The 20 mm case length makes it an ideal choice for internal mounting within bearing housings where space is constrained. By utilizing FluidLoc technology, this probe prevents process fluids or lubricating oils from wicking through the cable into the Proximitor sensor housing, which is a common failure point in pressurized machinery. The gold-plated ClickLoc connector provides a secure, vibration-resistant mechanical link, ensuring low-impedance signal transmission throughout the life of the machine.

Frequently Asked Questions

• Can I swap a standard cable probe for this FluidLoc version?Yes, the 330104-00-20-15-12-05 maintains the same electrical calibration as standard 3300 XL 8mm probes. However, ensure that the total system length (Probe + Extension Cable) matches the Proximitor sensor's calibration (typically 5.0 or 9.0 meters).

• Does this probe require a specific extension cable?It requires a 3300 XL extension cable. For a 1.5-meter probe like the 330104-00-20-15-12-05, you must pair it with a 3.5-meter or 7.5-meter extension cable to reach standard system lengths.

• What is the benefit of the PPS tip?The Polyphenylene Sulfide tip provides excellent resistance to chemical corrosion and thermal degradation, preventing the sensing coil from being damaged by aggressive industrial lubricants.
