Parameter Analysis

The 330709-000-080-10-01-00 offers a low DC resistance (5.9 Ω) ensuring signal integrity. The PPS tip and stainless steel case provide robustness in harsh environments. The temperature range covers most industrial applications, though exposure below -34°C may affect the pressure seal. The M16 thread and 80 mm case length allow flexible mounting.

Application Scenarios

This proximity probe is ideal for vibration and position monitoring on turbines, compressors, pumps, and other rotating machinery. It is commonly used in conjunction with Bently Nevada 3300/3500 monitoring systems to detect shaft vibration, axial position, and eccentricity.

Installation Guide

Install the probe with the M16 x 1.5 thread into a suitable mounting hole. Apply recommended torque of 21.1 N·m (187 in·lb) for the probe case. Ensure the target surface meets minimum size requirements (30.5 mm flat, 152 mm shaft diameter). Connect the miniature coaxial ClickLoc connector to the extension cable, tightening finger tight (max 0.565 N·m). Maintain a minimum bend radius of 25.4 mm for the cable.

Compatibility

The 330709-000-080-10-01-00 is compatible with Bently Nevada 3300 XL and 3500 series monitoring systems. It requires a compatible extension cable and proximitor (e.g., 3300 XL 8 mm or 5 mm proximitor) for signal conditioning. The ClickLoc connector ensures secure connection.

Maintenance Advice

Periodically inspect the probe tip and cable for damage. Keep the connector clean and dry. Avoid exposing the probe to temperatures below -34°C to prevent pressure seal failure. Check torque settings during installation and after any maintenance.

Procurement Advice

When ordering, verify the exact model number 330709-000-080-10-01-00 to ensure correct configuration. Confirm total length (1.0 m) and connector type (miniature coaxial ClickLoc) match your system requirements. Purchase from authorized Bently Nevada channels to guarantee authenticity and warranty.
