Parameter Analysis

The 330709-000-230-90-01-00 offers a 9.0-meter cable length, suitable for installations where the probe must be located away from the monitor. The M16 x 1.5 thread ensures secure mounting, and the PPS tip provides excellent chemical resistance. The probe’s temperature range covers most industrial environments, and the stainless steel case ensures corrosion resistance.

Application Scenarios

This proximity probe is ideal for monitoring vibration and shaft position in critical rotating machinery, including turbines, compressors, pumps, and other industrial equipment. It is commonly used in oil & gas, power generation, and manufacturing plants for predictive maintenance and protection.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m. Ensure the target surface is clean and meets the minimum size requirements. Route the cable with a minimum bend radius of 25.4 mm to avoid damage. Connect using the miniature coaxial ClickLoc connector, tightening finger tight only.

Compatibility

The 330709-000-230-90-01-00 is compatible with Bently Nevada 3300 XL systems, including 3300/3500 monitors and proximity transducer systems. It is designed to work with standard 3300 XL extension cables and proximity probes.

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 (-30°F) to prevent premature failure of the pressure seal. Calibrate the system as per manufacturer recommendations.

Procurement Advice
