Product Overview

The Bently Nevada 330104-01-08-50-01-05 is a ruggedized 8mm proximity sensor designed for high-precision, non-contact displacement and vibration monitoring. Part of the industry-standard 3300 XL Transducer System, this probe is specifically engineered for environments where mechanical protection is a priority. It features a robust armored cable to prevent abrasions and fluid ingress in heavy-duty machinery. By utilizing an eddy current sensing principle, it provides critical data on shaft position and radial vibration for Turbine Supervisory Instrumentation (TSI) systems. This module is fully interchangeable with other 3300 XL components, eliminating the need for tedious bench calibration or component matching during field replacement.

Strategic Industrial Implementations

Hydrocarbon Processing and Refining

The 330104-01-08-50-01-05 is extensively used in centrifugal compressors and large pumps within refineries. The armored cable is essential here to protect signal integrity from the corrosive effects of oils and heavy vibration.

Power Generation Turbines

In steam and gas turbine monitoring, this probe tracks radial vibration and axial thrust. Its PPS tip encapsulation allows it to maintain accuracy even when exposed to the high temperatures typical of turbine bearing housings.

High-Speed Rotating Machinery

Perfect for monitoring motors and gearboxes where shaft speeds require high-frequency response. The ClickLoc connector ensures the electrical path remains secure despite constant mechanical oscillation.

Hazardous Zone Monitoring

Given its multiple global safety certifications, this probe is the standard choice for monitoring equipment in Zone 0 and Zone 1 environments where explosive gas mixtures may be present.

FAQ

Q: Does the 8-meter length of the 330104-01-08-50-01-05 require an extension cable?

A: This specific probe features an 8-meter integrated cable. Depending on your system configuration (5-meter or 9-meter total), you must ensure it is paired with the corresponding Proximitor. Typically, an 8-meter probe is used with a 1-meter Proximitor to reach a 9-meter system total.

Q: What is the benefit of the armored coating on the sensor cable?

A: The stainless steel armor provides a physical barrier against crushing, kinking, and abrasion. It also helps prevent chemical degradation of the internal fluoropolymer insulation in environments with heavy oil or solvent exposure.

Q: Is it necessary to calibrate the probe to the Proximitor sensor before installation?

A: No. One of the primary advantages of the 3300 XL 8mm system is complete interchangeability. Any 3300 XL probe can be used with any 3300 XL extension cable and Proximitor without re-calibration, provided the total electrical length is correct.

Q: Can this probe be used to measure speed or just vibration?

A: It can do both. While primarily used for vibration and position, it is frequently employed as a Keyphasor or tachometer sensor by detecting a notch or projection on the rotating shaft.

Q: How does the PPS plastic tip improve the probe's lifespan?

A: Polyphenylene Sulfide (PPS) is a high-performance thermoplastic that is highly resistant to chemical attack and can withstand higher operating temperatures than standard epoxy tips, preventing the sensing coil from shifting or failing over time.
