Parameter Analysis

The 330709-000-230-50-11-05 probe is designed for use with the five meter Proximitor Sensor only. Its resistance of 7.2 ± 0.8 ohms ensures proper matching with the proximitor. The PPS tip and stainless steel case provide durability in harsh environments. The temperature range allows operation in extreme conditions, though exposure below -34°C may affect the pressure seal.

Application Scenarios

This probe is ideal for monitoring vibration and position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil & gas, power generation, and industrial process industries where reliable condition monitoring is critical.

Installation Guide

Install the probe with M16 x 1.5 thread into a suitable mounting hole. Apply recommended torque of 21.1 N•m (187 in•lb) to the probe case. Ensure the target surface is flat and has a minimum diameter of 30.5 mm (1.2 in) for flat surfaces, or a shaft diameter of at least 152 mm (6.0 in). Connect the ClickLoc connector to the extension cable, tightening finger tight only. Avoid bending the cable beyond a 25.4 mm radius.

Compatibility

This probe is designed for use with Bently Nevada 3300 XL system components, specifically the five meter Proximitor Sensor. It is not compatible with other proximitor lengths. The miniature coaxial ClickLoc connector is compatible with standard 3300 XL extension cables.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Keep the probe tip clean and free of debris. Avoid exposing the probe to temperatures below -34°C to prevent premature failure of the pressure seal. Check connector tightness periodically, but do not overtighten.

Procurement Advice

When ordering, verify the model number 330709-000-230-50-11-05 to ensure correct configuration. Confirm the cable length (5.0 meters) and connector type (miniature coaxial ClickLoc) match your system requirements. Ensure you have the corresponding five meter Proximitor Sensor.
