Bently Nevada 330192-00-68-05-05 3300 XL 8 mm ETR Probe Proximity Transducer System

Description

The Bently Nevada 330192-00-68-05-05 is an Extended Temperature Range (ETR) 3300 XL 8 mm proximity probe designed for reliable non-contact vibration and position measurements in high-temperature rotating machinery applications. It features a 3/8-24 UNF threaded stainless steel armored probe with a 6.8-inch case length and an integrated 0.5-meter cable. As part of the 3300 XL 8 mm Proximity Transducer System, the probe provides an output proportional to the distance between the probe tip and the conductive target, enabling accurate shaft vibration and axial position monitoring. The probe is fully interchangeable with other 3300 XL system components and is supplied with CSA, ATEX, and IECEx hazardous area approvals for demanding industrial environments.

Frequently asked questions

Q:What is the Bently Nevada 330192-00-68-05-05?
A:The Bently Nevada 330192-00-68-05-05 is an industrial 3300 XL 8 mm Extended Temperature Range (ETR) Proximity Probe with stainless steel armor.

Q:What makes the 330192-00-68-05-05 ETR series different from standard 3300 XL probes?
A:Standard 3300 XL probes are limited to +177°C (+350°F). The ETR (Extended Temperature Range) design upgrades the internal construction. This allows the probe tip to function reliably at continuous temperatures up to +218°C (+425°F), and the integrated cable to handle up to +260°C (+500°F)

Q:Is 330192-00-68-05-05 approved for hazardous areas?
A:Yes. The Bently Nevada 330192-00-68-05-05 is approved for hazardous area installations with CSA ATEX and IECEx certifications under Agency Approval Option 05.

Application areas

The Bently Nevada 330192-00-68-05-05 is an Extended Temperature Range (ETR) proximity probe wrapped in rugged stainless steel armor.

• Differential Expansion: Measuring the relative structural growth difference between the hot turbine rotor and the casing during startup and shutdown cycles.
• Bearing Compartment Monitoring: Positioned inside or adjacent to the hot-end bearings (near the combustion and exhaust sections) where standard sensors would melt or fail prematurely.
• Boiler Feed Pumps: Installed on critical high-pressure water pumps within power plants.
• Corrosive & High-Abuse Environments: The stainless steel armor casing protects the delicate inner coaxial cable from being crushed, cut, or damaged by flying debris, maintenance foot traffic, or aggressive chemical washdowns.
