Bently Nevada 330193-09-20-10-00 3300 XL 8 mm ETR Proximity Probe

Description

The 330193-09-20-10-00 is an 8 mm ETR (Extended Temperature Range) proximity probe designed for non-contact eddy-current displacement measurement in demanding industrial environments. This configuration features an M10 x 1 thread, a 0.9 in unthreaded length (Option 09), an overall case length of 2.0 in (Option 20), and a 1.0 m total length (Option 10). As an ETR-series component, it is engineered to maintain system accuracy under wider thermal conditions compared to standard 3300 XL probes, while remaining fully compatible with the 3300 XL Proximitor sensor and standard 3300 XL extension cables.

This probe is intended for use in 3300 XL 8 mm transducer systems to monitor shaft vibration and axial position on critical rotating machinery such as turbines, compressors, and pumps. The unarmored design (Option 00 for connector/cable) requires careful routing to prevent mechanical damage. This specific SKU does not include agency approval (Option 00), making it suitable for non-hazardous locations where specific certification packages are not required.

Features

• M10 x 1 thread for standard metric mounting applications

• 0.9 in unthreaded length and 2.0 in total case length
• 1.0 m system length (probe-to-connector)
• Miniature ClickLoc coaxial connector
• Compatible with standard 3300 XL Proximitor sensors and 3300 XL extension cables

Applications

• Turbine and compressor shaft vibration monitoring
• Rotor axial position measurement
• Critical rotating machinery protection
• High-temperature industrial process monitoring

Installation Guidelines

Ensure the probe is installed using an M10 x 1 threaded mounting bracket to maintain electrical isolation if required. When gapping the probe, verify the gap voltage using a digital multimeter at the Proximitor sensor terminals. Ensure the coaxial cable is routed away from high-voltage lines and sources of extreme electromagnetic interference. Secure the cable to minimize vibration, ensuring the minimum bend radius is observed during routing to prevent damage to the connector and cable jacket.
