E 90/1

Weighing Instrumentation Atex and Stainless Steel

DOWNLOADS

  • Designed for installation in potentially explosive environments
  • Complete digital programming of the instrument directly from the front 
  • RS232 or RS422/RS485, MODBUS RTU or ASCII protocols
  • Instrument suitable for use in many applications required by most industries in the chemical, pharmaceutical and paint
  • Intrinsically safe barriers housed into the deflagration case
  • The instrument E 90/1 can be interfaced with most popular PLCs via Profibus-DP -installable as an option directly in the instrument
