Parameter Analysis

The 330710-000-050-50-02-00 offers a 5-meter cable length, which is specifically matched to the five-meter Proximitor for accurate signal transmission. The probe’s DC resistance of 7.2 ± 0.8 ohms ensures consistent performance. The M16x1.5 thread and 50 mm case length provide robust mounting options. The miniature coaxial ClickLoc connector allows quick and secure installation. The probe is designed for flat target surfaces with a recommended minimum diameter of 30.5 mm (1.2 in) and shaft diameters of at least 152 mm (6.0 in) to avoid cross-talk limitations.

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 critical applications such as steam turbines, gas turbines, centrifugal compressors, and large pumps where precise measurement is essential for predictive maintenance and machine protection.

Installation Guide

When installing the 330710-000-050-50-02-00, ensure the probe case is torqued to 63.3 N•m (560 in•lb) for M16x1.5 threads. The connector should be finger tight, with a maximum torque of 0.565 N•m (5 in•lb). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. The probe must be used with the five-meter Proximitor Sensor only. Verify that the target surface meets the recommended size to avoid cross-talk.

Compatibility

The 330710-000-050-50-02-00 is part of the 3300 XL series and is compatible with Bently Nevada 3300/3500 monitoring systems when paired with the appropriate Proximitor. It is designed for use with the five-meter Proximitor Sensor only.

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) as this may cause premature failure of the pressure seal. Ensure proper torque during installation to prevent loosening.

Procurement Advice

When ordering the Bently Nevada 330710-000-050-50-02-00, confirm that the total length (5.0 meters) matches your application requirements. Verify that the thread type (M16x1.5) is suitable for your mounting configuration. This probe is an authentic Bently Nevada product, made in the USA, ensuring high quality and reliability.
