Description

Configured with a 5.0-meter total length and a 2.7-inch overall case length with no unthreaded portion, the Bently Nevada 330101-00-27-50-02-05 represents a specific non-armored 3/8-24 UNF threaded 8 mm proximity probe variant. This configuration utilizes a miniature coaxial ClickLoc connector on a standard cable and is certified with CSA, ATEX, and IECEx approvals. Because it features a 5.0-meter total cable length, this proximity probe is explicitly designed to pair directly with a 5-meter Proximitor sensor without the use of an intermediate extension cable, making it an ideal choice for compact installations where extra connection points must be minimized to maintain signal integrity.

As part of the 3300 XL 8 mm Proximity Transducer System, the probe operates on the eddy-current principle to provide high-precision, non-contact displacement and vibration measurements. The robust construction features a polyphenylene sulfide (PPS) tip and a stainless steel probe body, providing excellent resistance to harsh environments such as those found on steam or gas turbines, centrifugal compressors, and industrial pumps. It integrates seamlessly into 3300 XL monitoring systems and 3500 protection racks to provide continuous machinery health data.

Features

• 8 mm tip diameter proximity probe designed for reliable, non-contact eddy-current displacement measurements.
• Rugged polyphenylene sulfide (PPS) tip and high-grade stainless steel probe body suited for harsh industrial machine environments.
• 5.0-meter total length, enabling direct connection to a 5-meter Proximitor sensor without intermediate cabling.
• Standard coaxial cable equipped with a miniature ClickLoc connector for reliable RF transmission.
• Excellent structural integrity with built-in pressure sealing between the probe tip and the case.
• Hazardous area approvals (CSA, ATEX, and IECEx) for use in intrinsically safe and non-incendive environments.

Applications

• Non-contact shaft vibration and radial position measurement in power-generation turbines.
• Axial thrust position and rotor displacement monitoring in high-speed centrifugal compressors.
• Bearing housing and machine casing mounting for industrial pump diagnostics.
• Critical rotating machinery protection and continuous condition monitoring.

Technical Specifications

Installation Guidelines

• Mount the probe with the appropriate probe gap per system calibration requirements to maintain measurement accuracy.
• Verify that the maximum thread engagement does not exceed 0.563 inches (per industry standard limits for 3/8-24 UNF threads) to prevent mechanical binding.
• Route the standard cable with proper shielding and grounding practices to prevent electromagnetic or radio-frequency interference.
• Ensure the ClickLoc connection is clean and securely mated; use appropriate sealing or protection if exposed to liquids or turbine oil.

Compliance and Certifications

• CSA, ATEX, IECEx approvals for hazardous areas.
• Suitable for intrinsically safe (Ex ia) and non-incendive (Ex nA / Ex ec) installations in Class I, Zones 0, 1, and 2 or Class I, Division 1 and 2 environments.
