The Bently Nevada 3300 XL 25 mm Proximity Probe 330851-02-000-050-50-00-05 is a specialized 25mm proximity transducer system designed for differential expansion measurements in large turbine applications. This configuration features an M30x2 threaded connection with a 50mm minimum unthreaded length and comes without armor protection, making it suitable for precise installation in constrained spaces. The system includes a 5.0-meter cable and carries multiple international approvals for global industrial use.

This 330851-02-000-050-50-00-05 Bently Nevada 25 mm Proximity Probe delivers a 0.787 V/mm (20 mV/mil) output with an extensive linear range of 12.7 mm (500 mils), specifically engineered for monitoring differential expansion between turbine rotors and stationary components. The complete system consists of three key components: the 25mm probe, extension cable, and 3300 XL 25mm Proximitor Sensor, working together to provide accurate position data.

The primary application for the 330851-02-000-050-50-00-05 Bently Nevada is measuring differential expansion in mid-size to large steam turbine generators, where it tracks the differential growth rates between rotating and stationary elements. This measurement is critical for preventing internal rubbing and maintaining safe operational clearances during turbine startup, shutdown, and load changes.

Engineered for reliability in demanding power generation environments, the Proximity Probe 330851-02-000-050-50-00-05 represents Bently Nevada's expertise in large-scale machinery protection. This 330851-02-000-050-50-00-05 Bently Nevada 3300 XL 25 mm Proximity Probe demonstrates the manufacturer's commitment to providing specialized monitoring solutions for critical turbine protection applications where precise clearance monitoring is essential for operational safety and equipment longevity.
