Intrinsically safe weighing instruments

Hardy Process Solutions has introduced two UL–rated intrinsically safe weighing indicators designed for hazardous areas. The HI 8100IS and the HI8200IS are high-performance weighing instruments designed to operate in all Classes, Divisions, and Groups in accordance with U.S. UL and American National Standards Institute (ANSI) and with CAN Standards.

Both Hardy Process Solutions instruments feature two available power options: AC line power for permanent installation in the hazardous area; or external rechargeable battery packs that are can be switched out for recharging in the safe area.

The instruments have optional serial communication interface delivered over two fibre optic ports to bring data out to a safe area or to daisy chain the instruments to an optional remote display.

The HI 8100IS is a basic five-button indicator, while the HI 8200IS is an advanced indicator with check weighing features.

Each instrument supports up to four 350-ohm load cells suitable for interface with IS-certified floor scales or tank and hopper scales. The instruments feature IP6X, 304 stainless steel construction.
