Quick Detail

Description

The 330851-04-000-030-10-00-05 3300 XL 25 mm Proximity Probe features a smooth 1.06-inch diameter side-exit case with a 30 mm overall length and a 25.4 mm vertical probe adapter travel, enabling precise differential expansion measurements on midsize to large steam turbines. Its 0.787 V/mm (20 mV/mil) output provides a 12.7 mm linear range for accurate rotor-to-stator monitoring. The 330851-04-000-030-10-00-05 3300 XL 25 mm Proximity Probe operates continuously from -35°C to +200°C, and tolerates short-term exposure up to +250°C, with a 1.0-metre extension cable for flexible placement in automation systems. The PEEK probe tip and AISI 304 stainless steel case protect against harsh turbine conditions. ClickLoc connectors and removable collars on the 330851-04-000-030-10-00-05 3300 XL 25 mm Proximity Probe simplify cable routing through tight clearances, while front and rear seals with FluidLoc cable prevent moisture intrusion. Designed to replace older 7200 DE probes, this 330851-04-000-030-10-00-05 3300 XL 25 mm Proximity Probe integrates seamlessly with 3300 XL Proximitor Sensors, enabling precise high-temperature automation monitoring with minimal installation adjustments.
