The 76683-90 is a high-temperature 35 mm Proximitor Sensor designed for precise differential expansion (DE) and shaft position monitoring in medium and large steam turbines. It is part of a 35 mm proximity transducer system that includes a 7200 series probe, extension cable, and the Proximitor sensor, which conditions and converts displacement signals into usable electrical outputs for machinery monitoring systems.
The 76683-90 is specifically engineered for applications where the measurement range exceeds 4 mm and operating temperatures are above 125°C. It provides stable signal conditioning for critical turbine environments, ensuring accurate measurement of rotor-to-stator expansion and shaft movement under extreme conditions.
Constructed with a durable A380 aluminum housing, the sensor offers excellent corrosion resistance and long-term reliability. It supports combined system electrical lengths up to 9 meters and integrates seamlessly with Bently Nevada monitoring systems for industrial protection and diagnostics.
