There are a wide variety of digital scales used in different industries. They include bench scales, floor scales, and parts counting scales. A less common, but important type are hanging scales.
Industries That Use Digital Hanging Scales
Hanging scales are used in many industries for various weighing functions. They are used in industries such as scientific research, manufacturing, and many outdoor weighing functions. These scales are extremely useful because of their portability, precision, and durable design.
The portability of their design is one of the reasons that hanging weight scales are so popular. These scales include one hook at the top, which is used to hang the scale from some sturdy structure. Another hook is included at the bottom of the scale.
The item to be weighed is suspended from the bottom hook. It uses a load cell to measure and calculate the weight to be displayed on an electronic readout. If the item or items to be weighed are not easily hung from the scale or are very numerous, a pan or scoop can be hung from the scale, instead.
Consumer & Commercial Grade Hanging Scales
Relatively inexpensive hanging scales are used in supermarkets to make it easy for individual consumers to find out how much their vegetable or fruit purchases are going to cost. These are often spring scales, with limited precision and ruggedness.
A commercial-grade digital hanging scale is very accurate and may also include capabilities for many other functions such as the capability to switch weight measuring units. This would allow for weights to be read in pounds, ounces, grams, kilograms, or many other choices. The precision of this type of instrument allows the user to weigh in confidence, knowing that their results are valid.
These hanging scales must sometimes withstand a large amount of weight. Therefore, they are constructed from high-quality materials, such as heavy-duty stainless steel, that are tested to be durable enough to withstand the heavyweights.
Features Of Hanging Scales
In its simplest form, a hanging scale simply displays the weight of the load. Additional features, though, can make it more versatile.
The size of the display is directly related to the ease of reading the weight results. Arlyn’s standard indicator features 1” high graphics digits. The UpScale color touchscreen indicator provides easy to read, backlit, 2” digits, which expand to 3” height in the scoreboard mode.
Both indicators provide a choice of weighing units. They include a tare button, allowing the weight of any pans, slings, or other holding devices to be automatically subtracted from the results. The net / gross button gives the user a method of toggling between those modes.
There are situations where it can be important to record the weight of each load. The optional data-logging function can record thousands of results in a thumb drive. This can later be offloaded into a computer spreadsheet or database.
Power is not always easily accessible to a scale of this type. Batteries must often be used as an alternative power source. Good design will allow the unit to operate for many hours before the battery pack is fully depleted.
For the best user experience, rechargeable batteries are an excellent choice. Good quality rechargeable packs have virtually the same operating life as disposable batteries. A spare pack allows almost non stop usage.
The best rechargeable cells will retain their charge for a number of years, with a minimum level of self-discharge. To provide maintenance-free operation for many years, they also can be recharged for hundreds of cycles.
The purpose of using any scale is to achieve precision weight readings. Some applications are particularly sensitive to high accuracy. This can often be the case in the pharmaceutical and chemical industries.
Standard industrial scales use strain gauge load cells. This is a decades-old technology that provides tried and true results. High-quality manufacturers utilize heat-treated stainless steel for the load cells to provide years of abuse-resistant performance.
The accuracy level of these load cells is often suitable for the required use. Moderate precision is quite adequate for weighing commodities or dispensing ingredients. As with all industrial applications, it is generally not useful to significantly exceed the requested specifications.
But there are situations that demand much higher precision. This can be the case in the biopharmaceutical, chemical, and electronic industries. The allowed error in measuring may be much smaller than can be achieved by standard scales.
Ultra-precision scales, designed and manufactured by Arlyn Scales, provide ten to twenty times enhanced accuracy when compared to strain gauge scales. A unique semiconductor-based sensor technology operates completely in the digital domain. Weight capacities up to 500 kg can be achieved with a weight resolution of 5 g.
Hanging scales may be used in different locations of a typical manufacturing facility. It may not be feasible to equip each of these locations with a separate scale. The ability to quickly and easily move the scale to the required location is important.
Some parameters which help achieve the desired level of portability include a rechargeable battery pack, a large readout, and lightweight. Versatile load-receiving devices are also useful. A carrying handle can also be helpful.
Weight Ranges For Hanging Scale Installations
Hanging scales are generally designed to support weights from 20 to 20,000 pounds, depending on their construction. The scale resolution is typically proportional to the capacity.
