They do so by sending a small current through their probe tip. Current flowing between the sensor and some reference (often the metal tank holding the liquid) is compared inside the sensor to current ...

On-line conductivity measurement of mineral contamination in water allows reliable and inexpensive monitoring of water quality through the various stages of treatment. In comparison to having to ...

AutomationDirect has added new ProSense CLC series conductive liquid level controllers to their line of quality level sensors and controllers. The CLC series level controllers detect and control ...

Pressure sensors are important tools for accurate sensing of applied forces. However, they can mostly sense forces along only a single direction. In a new study, scientists from South Korea take ...
