Description

330851-02-000-080-10-00-00 3300 XL 25 mm Proximity Probe is a high-precision eddy current transducer for industrial automation and steam turbine monitoring. The 330851-02-000-080-10-00-00 3300 XL 25 mm probe features an M30x2 threaded stainless steel case, 80 mm overall length, and 1.0-meter (3.3 ft) extension cable. Its polyetheretherketone (PEEK) tip and FluidLoc cable ensure reliable operation in harsh environments, withstanding temperatures from -35°C to +200°C (-31°F to +392°F) and short-term peaks up to 250°C (482°F).

The 330851-02-000-080-10-00-00 3300 XL 25 mm probe provides a linear range of 12.7 mm (500 mils) with 0.787 V/mm (20 mV/mil) output, ideal for measuring Differential Expansion (DE) on midsize to large steam turbine generators. Its front and rear seals, high-temperature ClickLoc connectors, and optional sliding bracket facilitate precise installation and reliable automated monitoring. Fully compatible with 3300 XL 25 mm Proximitor Sensors, the 330851-02-000-080-10-00-00 3300 XL 25 mm probe supports accurate vibration, position, and DE measurements while offering robust durability, high-temperature resistance, and simplified field wiring for industrial automation systems.

Applications

Differential Expansion Measurement on Steam Turbines
The 330851-02-000-080-10-00-00 3300 XL 25 mm probe accurately measures differential expansion (DE) between turbine rotor and casing. With a linear range of 12.7 mm (500 mils) and 0.787 V/mm (20 mV/mil) output, this probe monitors axial movement in midsize to large steam turbines, ensuring safe and efficient automated operation.

Vibration Monitoring on Large Rotating Equipment
The 330851-02-000-080-10-00-00 3300 XL 25 mm probe detects dynamic vibrations in turbine generators and other industrial machinery. Its polyetheretherketone (PEEK) tip, AISI 304 stainless steel case, and FluidLoc cable allow stable operation from -35°C to +200°C (-31°F to +392°F), with short-term resistance up to 250°C (482°F).

Position Sensing and Alignment Verification
The 330851-02-000-080-10-00-00 3300 XL 25 mm probe measures static positions for alignment checks and Keyphasor references. Its M30x2 threaded case, 80 mm overall length, and 1.0-meter extension cable provide precise installation and repeatable measurements in automated monitoring systems.
