For potentially hazardous Class I, Div. 1 environments, Hardy Process Solutions has designed safety into
its components with an appropriate level of protection for different applications. Hardy recommends
using intrinsically safe low-energy components in hazardous areas (including instruments, load cells,
scales, and summing boxes) and limit power and current to them through intrinsic barriers that prevent
energy from crossing over from the safe area.
These devices limit current, voltage, & total energy delivered to a sensor or summing card located in a hazardous area. When used in areas with hazardous chemicals, gases, or other ignitable atmospheres, limiting the energy helps prevent any possible fires & explosions.
