Parameter Analysis

The 5-meter cable length is specifically matched to the five-meter Proximitor Sensor for optimal performance. The probe’s DC resistance of 7.2 ± 0.8 ohms ensures accurate signal transmission. The M16x1.5 thread and 50 mm case length provide versatile mounting options. The miniature coaxial ClickLoc connector allows quick and secure installation. Multiple approvals (option 05) ensure compliance with various international standards.

Application Scenarios

This probe is ideal for vibration and position monitoring on 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 reliable condition monitoring is essential to prevent downtime and equipment failure.

Installation Guide

Install the probe with the recommended torque of 63.3 N•m (560 in•lb) for the M16x1.5 case. Ensure the target surface meets the recommended minimum sizes: flat surface diameter of 30.5 mm (1.2 in) and shaft diameter of 152 mm (6.0 in) to avoid cross-talk limitations. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. Connect the ClickLoc connector finger tight, then tighten to a maximum of 0.565 N•m (5 in•lb). Verify that the total length matches the Proximitor sensor (5 meters).

Compatibility

This probe is designed for use with Bently Nevada 3300 XL system components, specifically the five-meter Proximitor Sensor. It is compatible with 3300/3500 series monitoring systems when paired with the appropriate Proximitor. The miniature coaxial ClickLoc connector ensures compatibility with standard extension cables.

Maintenance Advice

Regularly inspect the probe cable and connector for damage or wear. Keep the probe tip clean and free from debris. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. Check torque connections periodically to ensure secure mounting.

Procurement Advice

When ordering, verify the model number 330710-000-050-50-02-05 to ensure you receive the correct configuration. Confirm that your Proximitor sensor is a five-meter version. Consider purchasing from an authorized channel like TenBN to guarantee genuine Bently Nevada parts and technical support.
