Weighing scales are devices used to measure the weight of an object or person. They come in a variety of shapes, sizes and types depending on the purpose for which they are being used.
Generally, weighing scales use either spring-based mechanisms or electronic sensors to accurately measure weight. Weighing scales can be found in many different places such as homes, laboratories, hospitals and industries where accurate measurement is necessary.
Scales have been in use for centuries, and their importance and accuracy continue to grow thanks to the development of new technologies such as electronic sensors. With their variety of applications and forms, weighing scales are sure to remain a mainstay in modern society for many years to come.
Classifications of Scales
● Analog or Spring-based Scales
A spring-based weighing scale utilises a mechanism that behaves like a seesaw; when one side goes up, the other goes down accordingly. The force applied by the object being weighed is balanced out by springs that will stretch until it matches the force exerted by said object or person.
The amount of stretching done by these springs is then measured using a pointer on a dial face that indicates how much an object weighs in terms of pounds (lbs) or kilograms (kg).
These types of weighing scales are usually more affordable than their electronic counterparts. However, they tend to be less accurate due to wear and tear over time as well as incorrect calibration resulting from external factors such as temperature changes and humidity levels.
● Electronic or Digital Scales
Electronic weighing scales use sensors to measure the weight of an object or person. These sensors are usually connected to a digital display which provides accurate readings in grams (g) or kilograms (kg).
Digital weighing scales tend to be more expensive than spring-based scales but they offer greater accuracy and precision, making them ideal for use in professional settings such as laboratories and hospitals.
Additionally, electronic scales can detect small weight changes, allowing for precise measurements of even very light objects.
5 Types of Weighing Scale
1. Bench Scales
A bench scale is a type of weighing scale that is designed to be used on a flat surface, such as a desk or countertop. These scales are commonly found in commercial settings and industries due to their accuracy and convenience.
Bench weighing scales can measure items up to several hundred pounds with greater precision than other types of weighing scales. They also come in various sizes, making them suitable for any type of application.
This type of scale has an LCD panel that shows the weight measurement readings in either metric or imperial units. The most common features include the tare (zero) function, auto-off, hold or freeze feature and multiple unit conversions which make the process of measuring more efficient and accurate.
2. Platform Scales
A platform scale is a type of scale used for weighing various items, objects, and materials. They are designed with a platform or flat surface that supports the load being weighed.
They are commonly used in industrial, commercial, and laboratory settings for weighing goods, products, chemicals and other materials. Additionally, platform scales can be used to measure the weight of food items in grocery stores for accurate sales transactions.
These scales are incredibly versatile and can be used in many different applications, making them an essential tool in any weighing process. They are available in both mechanical and digital models.
3. Floor Scales
A floor scale is an essential tool for any business that needs to accurately measure and weigh items. Whether you need to track inventory, monitor shipments or keep records of production, floor scales provide the accuracy and precision needed for accurate weight measurements.
They also feature digital display screens for easy reading of results, as well as adjustable feet for stability on uneven surfaces.
4. Hanging Scales
A hanging scale is are a great option for any business that needs to measure weight accurately in smaller quantities. These scales feature an easy-to-read digital display and provide precise measurements with the use of a hook or suspension system.
They are also lightweight and portable so you can take them anywhere you need to measure items quickly and conveniently. With their accuracy, portability, convenience and affordability, these scales are the perfect solution for odd-shaped products or items.
5. Truck Scales
A truck scale is are an invaluable tool for any business that needs to accurately measure and weigh large items or shipments. These heavy-duty scales feature a robust design with adjustable feet for stability on uneven surfaces, as well as digital display screens for easy reading of results.
They offer extreme accuracy and precision when weighing items, making them ideal for tracking inventory, monitoring shipments or keeping records of production in the most efficient way possible. Truck scales also have reinforced load cells that can handle up to 80 tons without sacrificing accuracy and reliability.
