Intrinsically Safe Scale

Please browse our selection of intrinsically safe scale products and rely on Doran and Rice Lake's years of experience in hazardous area weighing applications. The equipment is Factory Mutual approved for use in hazardous areas. For use in volatile areas, Rice Lake Weighing Systems offers the very best in intrinsically safe and explosion-proof equipment. These devices require detailed attention to specification and installation guidelines. For IS system compatibility, use these intrinsically safe indicators with Rice Lake's selection of FM-approved load cells.

We offer the very best selection of intrinsically safe and explosion-proof equipment. This equipment requires attention to specification and installation guidelines. For IS system compatibility, our suppliers offer a complete line of FM-approved load cells that interface with these indicators in accordance with the official FM control drawings. Designed with the level of safety your location requires, the 320IS and 320IS Plus hazardous area scales meet hazardous environment requirements without hesitation. With Factory Mutual (FM) entity approval, it is the ideal solution for dangerous and highly explosive environments. An optional safe area I/O module allows communication with printers, computers and other peripherals. The IQ 700IS is designed to be operator friendly. The intrinsically-safe 115 VAC power supply has been designed for mounting within the hazardous area. The EL232 XPCD offers 20 mA current loop or RS-232 input, NEMA 4, 7CD, 9EFG enclosure, and is compatible with all IQ plusģ series indicators.

Caution The equipment contained within this Explosive Environment section requires greater attention to specification and installation guidelines. Improper specification, installation or service of these products can result in loss of equipment or serious injury.

Below are Rice Lake's definitions and examples of Explosion proof and Intrinsically safe systems. What is an explosion-proof indicator? Itís simply a digital weight indicator enclosed in a special case. The purpose of an explosion-proof indicator is not, as the name suggests, to protect the indicator. Instead, the case prevents any explosion WITHIN the case from causing subsequent fire or explosion in the surrounding atmosphere.

For example, in a grain elevator application, combustible dusts (Class II hazardous atmosphere) may be present. A spark in a non-explosion proof indicator could ignite an elevator-wide explosion. However, with an 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.

Intrinsically safe load cells and safety barriers take the explosion proof principle a step further. Intrinsic safety ensures that the indicatorís electrical wiring and components are, by design, 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.

Hazardous atmospheres are divided into three general classes and two divisions:
CLASS I: Flammable Gases or Vapors
CLASS II: Combustible Dusts
CLASS III: Ignitable Fibers or Flyings

DIVISION 1: Hazard exists under normal conditions.
DIVISION 2: Hazardous material is handled, processed or stored. Hazard is not normally present, but may be released due to accident or equipment malfunction.

Central Carolina Scale's individual suppliers warrant that all intrinsically safe (IS) equipment and systems installed by a distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed the individual manufacturers. All systems and components are warranted against defects in materials and workmanship for one year. All Intrinsically Safe equipment we offer carries a Factory Mutual approval and is documented. To preserve the warranty and Factory Mutual approval, all repairs or replacement of circuit boards or components housed within the enclosures must be performed by factory authorized personnel at the respective manufacturer of the equipment. The customer is responsible for choosing the correct equipment that meets their individual classification requirements.
