Explanation:
In addition to being a weighing indicator, PWI-FILL of the PWI series also functions as a controller that manages weighing instruments used in bagging, filling and discharging applications. With a stainless steel housing that can be either mounted on a panel or used on desk, PWI-FILL offers resistance to dust, water and impacts and this makes it quite suitable for severe industrial conditions and for such sectors as food and chemicals.
Consisting of a single unit, PWI-FILL does not require an additonal panel since it handles all the bagging, filling and discharging operations using its built-in software and hardware. It can be easily operated by connecting the relay outputs on the indicator to the filling control mechanisms. PWI-FILL can communicate with PLCs, computers, etc. thanks to its various industrial input and output options.
