PWI-EX EX-PROOF BOX
With its Ex-Proof housing, the PWI-E indicator of the PWI series offers resistance to flames and impacts, which makes it quite suitable for such environments where flammable chemicals, gases and petroleum products are present.
PWI-E finds application as an indicator in electronic weighing instruments. It can be used alone in various automatic weighing applications, and tank weighing, filling, discharging, batching and bagging systems as well, thanks to its various industrial input and output options. With PWI-E, it is also possible to communicate with PLCs, computers, etc.
