Intrinsically Safe Scales
An intrinsically safe weighing scale is a device designed specifically for hazardous areas and corrosive environments. This type of scale is explosion proof, resistant to extremely high temperatures, and will function in gas and dust mixtures. Our scales take safety that extra step. An intrinsically safe scale is considered safe when its design is such that it is incapable of releasing enough energy to ignite flammable or combustible atmospheric mixtures in their most easily ignitable concentrations. In short, an intrinsically safe device eliminates the conditions for an explosion no matter what the circumstances.
Using special components, materials, ratings and component layouts, all the electric circuits and interconnected cables are designed so that there is no chance of a spark or any ignition under fault conditions. In order to make their scales as safe as possible, a scale manufacturer will try to limit the voltage, current or any storable energy. Our intrinsically safe design combined with explosion proofing provides a protection system that gives the user unbeatable safety while offering the cost-efficiency of on-site weight indication.
Intrinsically safe weighing scales can be calibrated and maintained without any interruption in power, they allow you to use general purpose wiring methods for connecting the scale to a power source, and there is no need for safety permits for the surrounding area because you won't have to shut down the power for servicing.
An intrinsically safe weighing scale is considered safe in those locations where hazardous concentrations of flammable gases or vapors exist, where there are combustible or electrically conductive dust or fibers or where there might be hazardous gases due to equipment failure, i.e., breakdown of containers or ventilation equipment. These scales are also to be used wherever there might be acetylene, hydrogen, gases or vapors of equivalent hazard, such as manufactured gas, ethyl ether vapors, ethylene or cyclopropane, gasoline, hexane, naptha, benzine, butane, propane, alcohol, acetone, benzol, lacquer solvent vapors or other natural gases.
Grain Elevators: - a grain elevator, for example, often contains combustible dusts. A spark in a non-explosion-proof scale could ignite an elevator-wide explosion. However, with and explosion-proof indicator, the spark (or even an explosion) is contained within the case. The hazardous atmosphere cannot be ignited, and the elevator is protected.
