When a single terminal is not enough, multi-terminal designs are available, with agency-approved power supply, optional ISB (Intrinsically Safe Barrier) and additional features as required for the application.
|Operational Area||Process weighing; hazardous areas|
|Degree of protection||IP66|

The stainless steel enclosure housing the IND131xx DIN and IND331xx panel packaged solutions is FM-approved for use in safe areas, and in Division 2, Zone 2 hazardous areas. The enclosure is ATEX/IECEx certified for Zone 22 (dust) hazardous areas. Cable entry points can be either conduit hubs for use in the U.S., or ATEX-approved glands for European applications.
In applications with load cells installed in Division 1/Zone 1 or Zone 1/21 areas, an intrinsically safe analog load cell barrier (ISB) is required. IND131xx and IND331xx terminals packaged with a METTLER TOLEDO ISB05 intrinsically safe barrier provide an integrated solution for such applications – click on the image at right to see a typical installation, including an IND131xx, ISB and power supply. Refer to the control drawing (available on the documentation tab of this page) for load cell compatibility.
