Installation Guide

Install the probe with recommended torque of 21.1 N•m (187 in•lb). Ensure the target surface is flat and has a minimum diameter of 30.5 mm (1.2 in) for flat surfaces, or a shaft diameter of at least 152 mm (6.0 in). Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable. The connector should be finger tight, with a maximum torque of 0.565 N•m (5 in•lb).

Compatibility

The 330709-000-080-90-01-00 is compatible with Bently Nevada 3300 XL monitoring systems, including 3300/3500 series monitors and proximitors. It is designed to work with extension cables and other system components.

Maintenance Advice

Regularly inspect the probe and cable for damage. Avoid exposing the probe to temperatures below -34°C (-30°F) as this may cause premature failure of the pressure seal. Clean the probe tip with a soft cloth if contaminated. Ensure connectors are properly tightened.

Procurement Advice

When ordering, verify the model number 330709-000-080-90-01-00 to ensure it matches your requirements. Consider purchasing spare probes to minimize downtime. Check the agency approval requirements for your specific application.
