The model 330878-51-05 is a high-reliability eddy current proximity transducer system designed for continuous measurement of shaft vibration and axial displacement in rotating machinery. It uses a non-contact sensing principle to detect micro-scale variations in the distance between the probe tip and the conductive target surface.
This system is widely applied in machinery protection and condition monitoring applications where real-time vibration data is essential for safe operation. It is commonly used in turbines, compressors, pumps, generators, and other high-speed rotating equipment.
The “51-05” configuration typically represents a specific cable length, calibration variant, or installation-oriented design within the same probe architecture.
The product belongs to a globally recognized industrial condition monitoring and machinery protection technology manufacturer specializing in vibration monitoring systems, proximity sensing technologies, and predictive maintenance instrumentation.
