Memosens - Contactless sensor coupling
Moisture, potential interference and other harsh environmental conditions often pose problems for metallic sensor contacts. They can lead to reductions in sensor service life and may influence the measurement results. In order to eliminate problems like these, Memosens sensors are equipped with an inductive connection that is resistant to interfering influences.
