Parameter Analysis

The 330709-000-230-90-02-00 offers a 9.0-meter cable length, ideal for installations where the monitor is remote from the measurement point. The 11 mm probe size provides a linear range suitable for most rotating machinery applications. The PPS tip and stainless steel case ensure durability in harsh environments. The probe’s DC resistance is tightly controlled for consistent performance.

Application Scenarios

This proximity probe is widely used for monitoring radial vibration and axial position in turbines, compressors, pumps, and other rotating machinery. It is compatible with Bently Nevada 3300 XL monitoring systems, providing critical data for predictive maintenance and machine protection.

Installation Guide

Install the probe with recommended torque of 21.1 N•m (187 in•lb) for M16x1.5 cases. 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, with a maximum torque of 0.565 N•m (5 in•lb).

Compatibility

Compatible with Bently Nevada 3300 XL monitoring systems, including 3300/3500 series monitors. The probe works with standard extension cables and proximitors designed for 3300 XL 11 mm probes.

Maintenance Advice

Regularly inspect the probe tip for damage or contamination. Ensure the cable is not bent beyond the minimum radius. Check connector tightness periodically. Avoid exposing the probe to temperatures below -34°C (-30°F) during operation to prevent premature failure of the pressure seal.

Procurement Advice

When ordering, verify the model number 330709-000-230-90-02-00 to ensure exact specifications. Consider spare probes for critical machinery to minimize downtime. Purchase from authorized Bently Nevada channels to guarantee genuine parts and support.
