Operating Principles

of ZET 7140-S Digital Eddy Current Displacement Sensors

A digital eddy current sensor consists of a primary transducer (eddy current probe) and the ZET 7140-S measuring unit.

The primary transducer is installed on the object to be studied and is connected to the measuring unit. A signal proportionate to the distance to the studied object is generated at the primary transducer output. The measuring unit digitizes the sensor output signal and generates the measured value. The measurement results are transmitted via CAN interface.
