Product Overview

The 330101-36-80-10-02-05 is a specialized 8 mm eddy current proximity probe from the Bently Nevada 3300 XL series, engineered for high-precision machinery monitoring in complex mechanical configurations. This non-contacting transducer translates the distance between the probe tip and a conductive target into a proportional voltage signal, enabling real-time analysis of shaft vibration and position. This specific model is designed with an 8.0-inch case and a 3.6-inch unthreaded portion, making it ideal for "deep-reach" applications where the probe must pass through thick machine housings or insulation blankets to reach the bearing area. As a core element of a Turbine Supervisory Instrumentation (TSI) strategy, it provides the reliability needed for critical asset protection.

Industrial Deployment Scenarios

The extended reach of the 330101-36-80-10-02-05 makes it a preferred solution for large-scale rotating equipment in the power generation and oil and gas industries. It is frequently installed on industrial steam and gas turbines, centrifugal compressors, and heavy-duty gearboxes to monitor radial vibration and axial thrust position. In these environments, the probe's ability to operate accurately in high-temperature zones and its immunity to electromagnetic interference are critical for preventing false trips and ensuring early detection of rotor imbalances or bearing wear. Furthermore, its compatibility with SpringLoc terminal systems facilitates rapid and secure field wiring in high-vibration power plant applications.

FAQ

Q: What is the benefit of the 3.6-inch unthreaded length on this probe?

A: The unthreaded portion allows the probe to slide through a mounting sleeve or a smooth bore in a machine casing before the threads engage. This is particularly useful for reaching shafts that are set deep within a machine's internal architecture where continuous threading would be difficult to install.

Q: Can this probe be used in areas with heavy radio frequency interference?

A: Yes, the 3300 XL series is specifically engineered with enhanced RFI/EMI immunity. This allows the probe and its associated Proximitor to be installed in fiberglass housings or near high-frequency equipment without signal degradation or the need for specialized shielded conduit.

Q: Is the 330101-36-80-10-02-05 compatible with older 3300 series monitors?

A: This probe is fully backward compatible and interchangeable with non-XL 3300 series 5 mm and 8 mm transducer system components. This feature simplifies spare parts inventory and allows for incremental system upgrades without a total hardware overhaul.

Q: Does the cable on this probe include mechanical armor?

A: No, this specific model (option 10) is supplied with a standard 1.0-meter cable without armor. This provides maximum flexibility for routing through narrow internal conduits where the conduit itself provides the necessary mechanical protection.

Q: What is the significance of the ClickLoc connector?

A: The ClickLoc is a miniature gold-plated coaxial connector that provides a secure, vibration-resistant link to the extension cable. The "Click" mechanism ensures the technician knows the connection is fully seated, preventing signal loss due to loose couplings.
