Description

330876-01-90-00-00 is a high-performance proximity probe within the Bently Nevada 3300 XL 50 mm Proximity Transducer System, specifically engineered for differential expansion and rotor position monitoring in large steam turbine applications. Featuring a long measurement range of up to 27.9 mm, this probe delivers reliable displacement data for critical rotating machinery operating under demanding industrial conditions.

Designed for harsh environments, 330876-01-90-00-00 utilizes a rugged stainless-steel probe body, high-temperature FluidLoc cable technology, and advanced sealing construction to maintain measurement stability in temperatures up to 200°C. Its non-contact eddy current sensing technology helps reduce wear while improving machinery protection and predictive maintenance capabilities.

Compatible with 3300 XL 50 mm Proximitor Sensors, extension cables, and legacy 7200-series mounting configurations, 330876-01-90-00-00 enables seamless system upgrades without major monitoring modifications. It is widely deployed in power generation, oil & gas, petrochemical, and heavy industrial facilities where precise shaft movement and differential expansion measurements are essential for equipment reliability.
