Parameter Analysis

The 330709-000-230-10-01-00 offers a DC resistance of 5.9 ± 0.5 ohms, ensuring consistent performance with compatible proximitors. The probe’s construction from PPS and stainless steel provides durability in harsh environments. With a temperature rating up to +177°C, it suits high-temperature applications. The miniature coaxial ClickLoc connector simplifies installation and ensures a secure connection.

Application Scenarios

This probe is ideal for monitoring vibration and shaft position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil & gas, power generation, and manufacturing plants where reliable condition monitoring is critical to prevent unplanned downtime.

Installation Guide

Mount the probe with an M16 x 1.5 thread engagement of up to 24 mm. Apply a recommended torque of 21.1 N•m (187 in•lb) and do not exceed 63.3 N•m (560 in•lb). Ensure the target surface is flat with a minimum diameter of 30.5 mm (1.2 in) and a shaft diameter of at least 152 mm (6.0 in) to avoid cross-talk. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable.

Compatibility

This probe is part of the 3300 XL series and is compatible with Bently Nevada 3300/3500 monitoring systems. It requires a compatible proximitor (e.g., 3300 XL 8 mm or 11 mm) and extension cable to form a complete sensing chain.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Keep the connector clean and protected. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. Calibrate the system periodically to ensure measurement accuracy.

Procurement Advice

When ordering, verify the model number 330709-000-230-10-01-00 to ensure it matches your system requirements. Confirm total length, thread type, and connector options. Purchase from authorized distributors to guarantee genuine parts and warranty support.
