Description

The 330850-51-CN is a high-performance 3300 XL 25 mm Proximitor Sensor designed for accurate Differential Expansion (DE) and rotor position monitoring in steam turbine generator systems. It forms a critical part of the 3300 XL 25 mm Transducer System, operating together with a 25 mm proximity probe and extension cable to deliver stable, high-precision measurement signals.

The sensor accepts one non-contacting 3300 XL 25 mm Proximity Probe and Extension Cable, producing an output proportional to shaft displacement and rotor movement. With a sensitivity of 7.87 V/mm (200 mV/mil) and a frequency response up to 10 kHz, the module provides reliable monitoring of rotor-to-stator thermal expansion in medium and large turbine applications.

Constructed from durable A380 aluminum, the 330850-51-CN is engineered for harsh industrial environments and supports DIN rail mounting for compact control panel integration. The system supports a total cable length of 5.0 meters (16.4 ft) and maintains reliable performance across extreme operating temperatures from −51°C to +100°C.
