Electronic scales make everyday life easier

A scale is a device for everyday use with which the mass is determined via the weight force. The spring scale measures the weight force directly, the beam scale compares known masses with each other. Still others work with reference weights, such as beam scales. Scales that are not used as often and like to be carried around on the go are battery operated.

For frequent commercial weighing with the highest requirements, electronic scales are more practical to use. They are safe and secure in use even in the harsh industrial environment. Scales in industrial use, however, are not only for weighing but for formulating medicines to transportation, loading, storage and shipping applications. There are bench scales, pallet scales, rail scales, tank scales, floor scales and adaptable special scales.

Electronic scales are faster to read and usually less expensive. They have programs for calibration and are specially damped to prevent vibration. All electronic scales have in common that the weight force has to be transformed. This is done by a spring or a bending beam. In the direct method, the deformation of the spring is made visible via a strain gauge. In the indirect method, the change in capacitance of a capacitor is illustrated by the change in plate spacing.

Differentiation by accuracy
Precision balances can achieve an accuracy of up to 0.01 %. A distinction is made between microbalances (numerical increments of 1 µg), analytical balances (numerical increments of 0.1 mg), precision balances (numerical increments of 1 mg to 100 mg), commercial balances and coarse balances. Of course, the possible weighing range also plays a decisive role.

Electromechanical scales
Two sensor principles are used for this type of scales. On the one hand, there are scales with load cells, and on the other, scales that work with electromagnetic force compensation. Then there are scales with sensor elements that work with vibrating strings.

Bench scales
Bench scales are used for checking, counting, totalizing and filling. Well-designed weighing electronics, user menus, user-defined function keys and large, innovative displays make bench scales the most widely purchased scales of all. These scales have a wide reading range down to 0.001 g.

Floor Scales
Floor scales are very reliable, accurate, and are great for heavy-duty industrial applications. Floor scale models feature a MonoBloc load cell for maximum reliability. The rugged load cell housing has built-in overload protection and robust mechanical interfaces for many years of successful continuous use.

Truck Scales and Weighbridges
These types of scales are required for goods purchased per truckload. These monitor streams of goods delivered and unloaded in continuous operation, such as in processing and recycling plants. The truck scale consists of a concrete foundation, an LWK scale, the load cells, the terminal with the display, and the cables connecting the load cells to the terminals. Truck scales can lose accuracy due to continuous and heavy loads. Therefore, they need to be checked and recalibrated regularly.

Laboratory Balances
Laboratory balances are used in a wide variety of applications, whether in laboratories, schools, universities, quality control, etc.

Analytical balances
Analytical balances are mainly used in laboratories, universities, etc. because they are user-friendly, high quality and reliable.

Precision Balances
These balances are used in almost all fields.

Micro and ultra-micro balances
These balances are used to measure very small quantities. Of course, this requires just as much accuracy and care.

Mass comparators
These are required in mass metrology and trace back to the international original kilogram.

Electronic scales can be used in many areas of daily life, including the commercial and industrial sectors, facilitate other related operations in addition to weighing and have become an indispensable part of everyday life. And for good reason. For continuous use, electronic scales are more efficient and practical. They are characterized by robustness, precision, easy data handling and durability. These scales also feature user-friendly cleaning and maintenance. They can be operated with or without batteries, making them portable. Electronic scales make life much easier, whether in private or professional life.
