Eddy Current Sensors
Inductive Proximity Sensors using the eddy current principle are perfect for applications in harsh environments due to their high insensitivity to oil, dirt, dust, moisture and interference fields.
Eddy Current Sensors
These non-contact position sensors and position measurement systems rely on eddy currents. To measure a position, they transform the distance to a magnetizable or non-magnetizable metal surface into a proportional voltage output. Although the contactless position sensors are available for measurement ranges from 0.5 mm to 60 mm, most applications are between 1 and 6 mm. Since the area targeted by the eddy current sensor needs to be between 1.5 and 2.5 times the size of the measurement range in each direction, the target for a measurement of 60 mm would have to be at least 100 mm wide.
The ThreadChecker is a specialized version of these non-contacting distance sensors for detecting and identifying inside threads. This reduces losses in automated drilling, tapping, and driving processes.
