Overview
Explanation:
With its Ex Proof (explosion proof) coating, the PWI-E indicator of the PWI series offers flame and impact resistance, making it extremely suitable for environments where flammable chemicals, gases and petroleum products are found.
PWI-E is used as an indicator in electronic measuring devices. It can be used on its own in a variety of automated weighing applications as well as tank weighing, filling, discharging, dosing and packaging systems thanks to its various industrial input and output options. With PWI-E it is also possible to communicate with PLCs, computers and other devices.
