Quick Detail

Description

The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe is a 25 mm differential expansion transducer system for steam turbine automation. The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe includes a probe, extension cable, and Proximitor Sensor, delivering 0.787 V/mm output across a 12.7 mm linear range. Its probe case is AISI 304 stainless steel with PEEK tip, threaded M39x1.5, 70 mm length, and operates from -35 °C to +200 °C (short-term 250 °C). The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe measures rotor differential expansion using single or complementary transducer configurations and supplies linear outputs compatible with 7200 and 25 mm DE systems. The Proximitor Sensor’s thin design allows DIN-rail or panel mounting, with RFI/EMI immunity. SpringLoc terminals enable fast wiring, while optional sliding brackets facilitate precise probe alignment and gap verification. The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe supports automated DE monitoring and high-temperature operation for midsize to large turbine generators, ensuring accurate rotor movement tracking.

Applications

Measure Differential Expansion in Turbine Rotors

The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe measures rotor differential expansion with a linear range of 12.7 mm (0.787 V/mm output). Using single or complementary transducer setups, the 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe captures axial movement on steam turbine generators for automation monitoring.

Monitor High-Temperature Shaft Environments

The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe operates continuously from -35 °C to +200 °C, with short-term tolerance up to 250 °C, allowing accurate readings in high-temperature turbine casing areas.

Provide Linear Output for Automation Systems

The Proximitor Sensor in the 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe outputs signals identical to 7200 and 25 mm DE systems, enabling seamless integration into existing turbine monitoring automation without changing monitor configurations.

Facilitate Precise Probe Alignment

With optional sliding brackets, the 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe allows technicians to adjust the probe over 25.4 mm vertical travel, verifying alignment and linear gap for accurate shaft monitoring.

Track Long Distance Rotor Movements

The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe system supports extension cables up to 5 m (16.4 ft), enabling installation on midsize to large turbine generators while maintaining precise differential expansion measurements.

Specifications

Competitive Advantage

Direct Replacement for Legacy Systems

The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe fits all standard 7200 25 mm, 7200 35 mm, and DE integral probes, allowing upgrades without changing existing automation monitors.

High-Temperature and Moisture Resistance

The 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe tip is PEEK with dual front and rear seals, and FluidLoc cable prevents moisture ingress, ensuring operation in shafts up to 200 °C and intermittent 250 °C.

Flexible Mounting Options

The thin Proximitor Sensor design allows DIN-rail or panel mount, and the 330851-06-000-070-50-00-05 3300 XL 25 mm Proximity Probe supports threaded M39x1.5, M30x2, or English threads, and side or rear exit configurations.
