Verifying Ball Valve Position with Inductive Proximity Sensors
http://www.am.pepperl-fuchs.com - A chemical plant uses Ball Valves to sample and analyze chemicals during the production process. F25 inductive proximity sensors from Pepperl+Fuchs are used to determine the on/ off position of the ball Valves. The F25 inductive proximity sensors are installed with actuators. The inductive sensors are available in NAMUR, DC and AC types.

Fisher V-Ball valve test — chopping a pencil in half
