• Minimum Bend Radius: 25.4 mm (1.0 in)

Parameter Analysis

The 330709-000-060-50-11-05 is configured for use with a 5-meter Proximitor sensor. The probe resistance is tightly specified to ensure accurate signal transmission. The PPS tip and stainless steel case provide durability in harsh environments. The temperature range covers most industrial applications, though exposure below -34°C may affect the pressure seal.

Application Scenarios

This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, pumps, and other rotating machinery. It is commonly used in oil, gas, power generation, and petrochemical industries where reliable condition monitoring is critical.

Installation Guide

Install the probe with the recommended torque of 21.1 N•m (187 in•lb) for M16x1.5 threads. Ensure the target surface meets minimum diameter requirements: 30.5 mm for flat surfaces and 152 mm for shafts. Maintain a minimum bend radius of 25.4 mm for the cable. Connect using the ClickLoc connector, tightening finger tight only.

Compatibility

This probe is designed for use with Bently Nevada 3300 XL systems and is compatible with the 5-meter Proximitor sensor. It is part of the 3300 XL series, which includes models 330703, 330704, 330705, and 330709.

Maintenance Advice

Regularly inspect the probe tip and cable for damage. Keep the connector clean and properly torqued. Avoid exposing the probe to temperatures below -34°C to prevent premature pressure seal failure. Calibrate the system periodically to ensure accurate readings.

Procurement Advice

When ordering the 330709-000-060-50-11-05, verify the exact model number to ensure correct configuration. Consider purchasing spare probes to minimize downtime. Ensure compatibility with your existing Proximitor and monitoring system.
