Bently Nevada 330851-02-000-060-90-00-00 Probe

Technical Specifications

Product Overview

The Bently Nevada 330851-02-000-060-90-00-00 is a high-performance 3300 XL 25 mm proximity probe engineered for large-scale shaft position and differential expansion measurements in industrial turbomachinery. Featuring an M30x2 threaded 304 stainless steel case, 0 in unthreaded length, and 60 mm case length, this unarmored sensor includes an integrated 9.0-meter (29.5 ft) PFA FluidLoc cable. Weighing 230 g (0.23 kg) with a durable PEEK polymer tip, it operates reliably in harsh temperature environments up to 200°C (392°F).

Key Features

• Extended 25 mm Linear Range: Designed for high-displacement applications such as shaft differential expansion and axial position monitoring.
• PEEK Tip & 304 SS Housing: High-grade materials provide robust chemical resistance, mechanical durability, and thermal tolerance.
• 9.0-Meter FluidLoc Cable: Integrated 75 Ω triaxial cable with high fluid sealing prevents ingress along the lead path.
• Extreme Thermal Performance: Continuous operation up to 200°C with peak survival up to 250°C for demanding power generation environments.

Installation Essentials

Thread M30 housing to 68 N·m torque. Route 9m cable, set target gap, and prevent ESD damage.
