Contactless Capacitive Sensor Signal Conditioners Most Practical for Harsh Environments

摘要

Capacitive-based sensors have been in use for many years, but they are seeing a rapid increase in interest for a variety of reasons. One of the primary reasons for this is the expanding number of harsh environment applications where capacitive sensing is the best choice because it permits contactless sensing that is sealed from harsh or hazardous environments. Such harsh environments frequently occur in industrial control processes that contain corrosive chemicals, high temperatures, explosive gases, or even radioactive contamination.
