D440IS Weight Indicator

Weightron’s versatile D440iS ATEX certified weight indicator is ideal for a wide range of process weighing applications including filling, dosing, mixing and blending. It can be used in hazardous areas where both gases and/or dusts are present.

The D440iS can operate directly in the hazardous area (including Zones 0 and 20), without the need to install additional galvanic barriers through to the safe area. This not only saves installation costs, but also gives a much neater and more professional installation. The D440 can be connected to external weight displays, weight repeaters, PCs and printers located in the safe area. The dedicated PS440-A power supply is available in 230 VAC, 115 VAC and 24 VAC versions.

The D440iS features:

  • Stainless steel enclosure with large back-lit graphic display
  • 18 key alphanumeric keypad for simple set up and operation
  • Single and double weighing function
  • Four electro-mechanical relay outputs, four opto-isolated inputs and two bi-directional optical-fibre serial channels as standard (optional voltage or current analogue outputs are also available)
  • 4000 d OIML certification (Directive 2014/31/eu – Non-automatic weighing machines)

Certification overview:

  • Operating zones: Zones 0, 1, 2 (gases) and Zones 20, 21, 22 (dusts)
  • Certificate: CESI 05 ATEX 022X
  • ATEX Designation:
    • Ex II 1G Ex ia IIC T5 Ga
    • Ex II 1D Ex ia IIIC T100°C Da IP54
    • Tamb (-20°C to + 55°C) –> T5/T100°C

Please contact us to discuss the full capabilities of the DD440iS.

PLEASE NOTE: The installation of weighing equipment in designated ATEX hazardous areas must be carried out by suitably qualified personnel.
