Hardy Process Solutions, a provider of precision measurements in automation, has released two UL—rated intrinsically safe weighing indicators designed for hazardous areas. The HI 8100IS and the HI8200IS are designed to be high-performance weighing instruments that operate in all Classes, Divisions, and Groups* in accordance with U.S. UL and American National Standards Institute (ANSI) and with CAN Standards.
Both instruments are meant to feature two available power options: AC line power for permanent installation in the hazardous area; or high-performance external rechargeable battery packs that are easy to switch out for recharging in the safe area. For continuous battery power, maintaining multiple batteries should allow for fast swapping in/out. Both instruments have optional serial communication interface delivered over two fiber optic ports to bring data out to a safe area or to daisy chain the instruments to an optional remote display.
The HI 8200IS is made as an advanced indicator with checkweighing features. The instrument is meant for manufacturing processes where equipment operates near flammable gases; flammable or combustible liquid-produced vapors; combustible dusts or ignitable fibers; or flyings.
The HI 8200IS is supposed to be very versatile for a range of environments and weighing demands. With both battery or AC power options it should be able to serve everywhere from on-site testing where portable battery-powered equipment is required to large manufacturing facilities that facilitate permanent AC installation, according to the company. Specific applications and environments include fuel refineries, machinery maintenance, chemical plants, chemical storage, distilleries, and textile manufacturing.
The HI 8100IS is a basic five-button indicator designed for use in hazardous locations. It is ideal for manufacturing processes where equipment is exposed to flammable gases; flammable or combustible liquid-produced vapors; combustible dusts or ignitable fibers; or flyings.
The HI 8100IS also features both battery and AC power options. The simplified user interface makes it intuitive to use by a wide range of operators with varying degrees of technical expertise. The HI 8100IS is extremely versatile for a range of weighing demands, from tank-based inventory control to batching operations in chemical environments. Specific applications and environments include fuel refineries, machinery maintenance, chemical plants, chemical storage, distilleries, and textile manufacturing.
Each instrument is designed to support up to four 350-ohm load cells, meant for interface with IS-certified floor scales or tank and hopper scales. The instruments feature IP6X, 304 stainless steel construction for heavy washdown, and resistance to many chemicals, dust, and corrosion.
