Weight Indicator in Explosion Proof Box – W200 Series for ATEX Zones

The Laumas ADPEW200 is a high-performance W200 series weight indicator integrated in a rugged, explosion-proof aluminum enclosure. Certified for ATEX and IECEx zones, it is ideal for hazardous environments where safe and precise batching, loading, and weighing are critical. The ADPEW200 includes an internal W200 indicator with 6-button keypad, and 5 external magnetic switches for operation without opening the box. It supports RS485 communication with Modbus RTU, CANopen, Profibus DP, Ethernet/IP, Modbus TCP, and more. Extensive I/O capabilities, modular relay expansions, and fieldbus options make it perfect for industrial dosing systems in Ex-rated areas.
