Parameter Analysis

The 330709-000-040-10-12-05 is configured with a 40 mm overall case length and a 1.0 meter total length, making it suitable for installations where space is limited. The M16 x 1.5 thread ensures secure mounting, and the recommended installation torque is 21.1 N•m (187 in•lb), with a maximum of 63.3 N•m (560 in•lb). The probe’s DC resistance of 5.9 ± 0.5 ohms ensures accurate signal transmission. The minimum recommended target flat surface diameter is 30.5 mm (1.2 in), and the minimum shaft diameter is 152 mm (6.0 in).

Application Scenarios

This proximity probe is ideal for monitoring vibration and axial position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil & gas, power generation, and manufacturing industries to prevent machine failure and optimize maintenance schedules.

Installation Guide

Install the probe with the M16 x 1.5 thread into a suitable mounting hole. Apply the recommended torque of 21.1 N•m (187 in•lb) for proper seating. Ensure the probe tip is positioned correctly relative to the target surface, maintaining the recommended gap. Connect the ClickLoc connector to the extension cable, tightening finger tight, with a maximum torque of 0.565 N•m (5 in•lb). Avoid bending the cable below the minimum bend radius of 25.4 mm (1.0 in).

Compatibility

This probe is compatible with Bently Nevada 3300 XL series systems, including 3300/3500 monitors and proximitors. It uses a standard miniature coaxial ClickLoc connector, ensuring compatibility with matching extension cables and proximity transducers.

Maintenance Advice

Regularly inspect the probe cable and connector for damage. Keep the probe tip clean and free from debris. Avoid exposing the probe to temperatures below -34°C (-30°F) during operation, as this may affect the pressure seal. Periodically verify the probe resistance to ensure it remains within specification.

Procurement Advice

When ordering, verify the model number 330709-000-040-10-12-05 to ensure it matches your system requirements. Consider purchasing spare probes to minimize downtime. Ensure you have the correct extension cable and proximitor for your monitoring system.
