Power Generation Industry
Measures the relative thermal growth discrepancy between the steam turbine rotor and casing during startup and shutdown to prevent catastrophic rubs.
Oil & Gas Industry
Detects sudden shaft shifts or heavy vibrations in high-pressure process gas compressors to trigger emergency trip systems.
Chemical & Heavy Processing Industries
Functions as a critical input for critical safety interlock systems by continuously reporting rotor axial position in aggressive chemical areas.
Metallurgy & Mining Industries
Monitors the vast rotor displacement in steel plant air-supply blowers to handle high temperature and high volume air stress.
Marine, Water & General Heavy Machinery
Tracks propeller shaft thrust position changes caused by maritime hull flexing and varying marine propulsion thrusts. Monitors the relative positioning of low-speed high-torque shafts to protect internal gear meshes from uneven loading.
330850-50-05 is a Bently Nevada 3300 XL 25 mm Proximitor Sensor that supports a 5.0-meter total system length with panel mounting. It features multiple global hazardous area certifications and exceptional EMI immunity. Seamlessly backward compatible with legacy systems, this model serves as an industry-standard hardware solution to safeguard critical rotating machinery.
It serves as a proximity transducer to measure the distance between the sensor and a target object (e.g., turbine shaft) to monitor machinery vibration and position.
What is the 330850-50-05？
It signifies a 5.0-meter (16.4 feet) system length, usually including agency approval options.
What are the typical applications for the 330850-50-05 model?
It is ideal for monitoring Differential Expansion (DE) in large steam turbine generators, compression systems, and speed measurements.
Can the 330850-50-05 replace older models?
Yes, the 3300 XL 25 mm series is designed for backwards compatibility with previous 3300 XL transducer system components. However, for optimal performance when upgrading, it is advised to replace the entire system (probe, extension cable, and Proximitor).
What are the 330850-50-05 key features?
Features include an extended temperature range, high-density DIN-rail or panel mounting options, and improved RFI/EMI immunity for CE marking approval.
