Parameter Analysis
The probe’s DC resistance of 8.5 ± 1.1 ohms ensures consistent performance. The recommended minimum target size is 30.5 mm (1.2 in) flat surface, and minimum shaft diameter is 152 mm (6.0 in). The probe case torque rating is 63.3 N•m maximum, with recommended 21.1 N•m. Connector-to-connector torque is finger tight (max 0.565 N•m). Minimum bend radius is 25.4 mm (1.0 in). The probe is designed to seal differential pressure between tip and case, using a Viton O-ring.
Application Scenarios
This probe is ideal for monitoring vibration and axial position in turbines, compressors, pumps, and other rotating machinery. It is suitable for use in harsh environments, including hazardous areas, thanks to multiple approvals.
Installation Guide
Mount the probe with an M16 x 1.5 thread, ensuring proper torque (recommended 21.1 N•m). Maintain a minimum bend radius of 25.4 mm for the cable. Connect using the miniature coaxial ClickLoc connector, tightening finger tight only. Ensure the target surface meets minimum size requirements.
Compatibility
The 330710-000-050-90-02-05 is part of the 3300 XL series and is compatible with Bently Nevada 3300/3500 monitoring systems. It works with standard extension cables and proximitors.
Maintenance Advice
Regularly inspect the probe and cable for damage. Keep connectors clean and protected from moisture. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. Do not submerge the probe.
Procurement Advice
When ordering, verify the model number 330710-000-050-90-02-05 to ensure correct specifications. Consider spare probes for critical machinery to minimize downtime. Consult with TenBN for availability and technical support.
