Going wireless can streamline position monitoring in explosive environments

Switches operate at extremely low voltage and current; feature an electro-dynamic energy generator
Monitoring a control valve’s position in process industries is typically done using conventional cabled position switches meant for normal manufacturing environments. While these devices address the functional requirements for sensing “open/closed” valve positions, inherent design characteristics may limit their life expectancy or make them unsuitable for use in potentially explosive gas/dust environments.
