Product Overview
When vibration monitoring systems fail due to probe damage or signal degradation, the Bently Nevada 330709-000-080-10-11-00 3300 XL 11 mm Proximity Probe provides a robust solution. This probe is engineered for demanding industrial environments, featuring a polyphenylene sulfide (PPS) tip and AISI 304 stainless steel case. The 330709-000-080-10-11-00 uses a miniature coaxial ClickLoc connector with a connector protector and FluidLoc cable, ensuring secure connections and resistance to moisture and contaminants. With an operating temperature range of -52°C to +177°C, it handles extreme conditions without failure.

Installation and Setup
Proper installation of the 330709-000-080-10-11-00 ensures accurate readings and long service life. For M16x1.5 probe cases, apply the recommended torque of 21.1 N·m (187 in·lb) and do not exceed the maximum rated torque of 63.3 N·m (560 in·lb). The connector should be finger tight, with a maximum torque of 0.565 N·m (5 in·lb) to avoid damage. When routing the cable, maintain a minimum bend radius of 25.4 mm (1.0 in) to prevent internal conductor stress. Ensure the target surface is at least 30.5 mm wide and the shaft diameter is at least 152 mm to avoid cross-talk interference.
Maintenance and Reliability
The Bently Nevada 330709-000-080-10-11-00 3300 XL Proximity Probe is built to withstand harsh conditions, but regular inspection of the cable and connector is recommended. Check for cracks or wear on the FluidLoc cable and ensure the connector protector is intact. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal, so avoid such conditions. The probe's stainless steel case resists corrosion, and the PPS tip offers excellent chemical resistance. Routine checks of the DC resistance (5.9 ± 0.5 ohms for 1.0 m probe) can verify signal integrity.
Selection Guide
When ordering the 330709-000-080-10-11-00, verify that the unthreaded length (0 mm), overall case length (80 mm), and total length (1.0 meter) meet your application requirements. The probe comes with a miniature coaxial ClickLoc connector and FluidLoc cable, ideal for environments where moisture or vibration is present. For reliable supply and expert support, consider UBEST Automation (ubest101) as your sourcing partner. Ensure your system accepts 75 ohm triaxial FEP insulated cable and that the mounting thread (M16x1.5) matches your bracket or adapter.
