Δ About the Product

The Bently Nevada 330878-90-00 is a 3300 XL 50 mm Proximitor® Sensor that forms part of a non-contact eddy current transducer system for measuring vibration and displacement. It accepts one 3300 XL 50 mm proximity probe and extension cable, converting the probe's signal into a voltage output proportional to the target's position. It is an advanced sensor conditioning unit that accepts radio-frequency inputs from a 50 mm proximity probe and extension cable, converting the relative raw distance gaps into a highly accurate, linearly proportional analog DC voltage output for monitoring industrial machinery behavior.

Δ Real-World Applications

1) Differential Expansion (DE) Monitoring: Measuring the difference in relative expansion between the turbine rotor and its casing due to thermal stress during startup and shutdown in large steam turbine generators.

2) Rotor Expansion (RX) Tracking: Monitoring long-distance axial movement of the target shaft to ensure that moving parts do not collide with stationary components.

3) Machinery Protection: Providing critical input data for industrial turbines, generators, and large process compressors to prevent catastrophic failures.

4) Vibration and Displacement Measurement: Delivering precise, non-contact measurement of shaft position and vibration in rotating machinery for early fault detection and predictive maintenance.
