Based on electromagnetic induction, Eddy Current Sensors provide non-contact measurement of displacement, shaft position, and vibration in conductive metal targets. With fast response and rugged probes, they support axial position monitoring, radial vibration measurement, speed detection, and differential expansion monitoring, helping ensure reliable operation and protection of turbines and other rotating machinery.
The SensorsX SX-EEDNB series is a non-contact eddy current displacement measurement system for monitoring shaft position and vibration in rotating machinery. Each system consists of a probe, an extension cable and a matched preamplifier, providing a voltage output that represents the gap between the probe tip and an electrically conductive metal target. The system supports static position and dynamic vibration measurements. Probe size, measuring range and total cable length must be selected as a compatible configuration. Frequency response depends on the selected measuring range.
