Digital hanging scales are electronic versions of hanging spring scales. A spring scale is a weighing scale that measures the weight of an object by determining how much force the object exerts upon a spring which is enclosed in the body of the scale. Spring scales can be divided into two different categories: scales in which the spring stretches and scales in which the spring is compressed. This article will only focus on scales in which the spring is stretched by the item being weighed, or hanging scales.

Aggregates are everywhere we look in the world around us. These materials, which are made up of an aggregate of different other materials, including various types of stones, clay, silt, and sand, include the asphalt that paves our roads, the concrete that is used for the foundations of our skyscrapers, or the cement that makes up the bricks of our homes. There is no single aggregate-each one is made differently for a different purpose. One aggregate that uses a certain mixture of stones, silt, and petroleum-based binding may have very different characteristics than one that uses another mixture of pebbles, clay, and a different binding. One aggregate may be more suitable for roads while another may be more suitable for sidewalks.

Recycling programs have become widespread in many industries for several different reasons. Economically, it is extremely viable for companies to sell any unused materials, including steel, iron, glass, plastic, rubber, wood, paper, and precious metals, to recycling companies. Environmentally, any products that are reused rather than placed in landfills help protect valuable land and nature. Legally, it is becoming more and more common for states and municipalities to pass legislation required industrial entities to create these recycling programs. When recycled products are brought to recycling plants, these plants must first sort out the different products, and then must weigh them in order to determine how much to pay the donator. Digital platform scales are ideal for weighing this recycled material. These digital scales usually have a [+]

Industrial scales are often subject to very harsh conditions. A cylinder scale may have to support a 250 pound tilted liquid gas cylinder as it is being loaded on and off. A platform scale may be subject to high shock loads as large pallets are placed on it by a forklift. Parts counting scales may also have to support these shock loads if a large batch of parts are placed on it at one time.

The primary purpose of industrial scales is to simply weigh objects. How much of each chemical is being fed into this mixture? How much do those boxes weigh that are being loaded onto the truck? How many metal stampings are in the container? However, sometimes, it is just as important to collect this weight data from electronic scales as it is to do the actual weighing. It may be useful to keep track of how quickly the inventory of metal stampings is being used, what the total weight is of each truck that is leaving the warehouse, and the total quantity of chemicals that is used over the course of the week.

Every living being has an interest in our environment. We all need to breathe clean air and drink safe water. We would all like to be able to use the outdoors without being subjected to medical and other hazardous wastes. No one wants to deal with beaches that are littered with dangerous items, and no one wants to discover that inappropriate materials have been dumped in their neighborhoods.

For all of these reasons, there are many rules and regulations pertaining to the management of hazardous wastes. Some of these simply define what materials and items are deemed to be hazardous and which are not. Others outline the methods required for physically handling hazardous materials. There are specifications for the types of clear and accurate [+]

An industrial scale is a wonderful instrument for determining the weight of an item. Bench scales accurately weigh small items. Depending on the capacity of the digital scale, the readability of the weight can be as small as 0.0001 lb. Platform scales weigh larger packages and drums up to 1000 lb, whereas floor scales and pallet scales can accepts loads up to 20,000 lb. The accuracy of the electronic scale is dependent on the type of technology used. High quality industrial strain gage scales have an accuracy range of approximately 1/10 of 1%. If greater accuracy is required, alternate ultra precision scales, such as Arlyn Scales Surface Acoustic Wave technology can provide ten or even twenty times better accuracy. But even an industrial scale with the best accuracy obtainable will not [+]
