Design and Functional Characteristics

This sensor operates using the established eddy current principle for accurate gap measurement. The probe tip generates a high-frequency electromagnetic field during operation. This field then interacts with any nearby conductive target material, typically a machine shaft. Subsequently, the connected monitoring system detects specific changes in the field’s energy characteristics. These changes create a linear voltage output that directly corresponds to the distance to the target.

Furthermore, its compact 5mm diameter allows installation in space-limited mounting locations. The robust stainless steel housing provides reliable protection against moisture and mechanical impact. Additionally, the sensor contains no batteries or internal energy storage components. It draws all required operating power directly from its paired EPRO monitor, ensuring maintenance-free operation and long-term signal stability for continuous monitoring applications.
