Product Information

Balances are generally more sophisticated than scales and often used by professionals for advanced scientific weighing in laboratories, universities, medical facilities and research and development related environments. Types of balance include microbalances, analytical balance and precision balances. Berg balance scale scoring ranges from 0 to 56. The lower your score, the more at risk you are for losing your balance. In general, Berg balance scale scores are interpreted as such:

A Beam balance (or Beam scale) is a device to measure weight or mass. These are also known as mass scales, weight scales, mass balances, weight balances, or simply scales, balances, or balance scales. The Double Pan Balance Activity consists of six colourful worksheets, each featuring empty scales. On the first sheet, the scales are balanced, but other worksheets feature varying imbalances. Children will choose an object they want to compare and draw it on the left scale. They will then need to experiment using the scales until they find an object that corresponds to the sheet (for example, if they have chosen an object that is slightly heavier, they will need to find an object that is slightly lighter and vice versa). They will then draw this on the right scale. Weighing scales are similar to balances, however a balance determines mass by balancing an unknown mass against a known mass.Over time, scales can lose accuracy due to wear and tear from regular use and age. Scales must maintain their original balance for accuracy, but because over time they tend to lose this balance they will require recalibration. Electronic scales may suffer electrical malfunction over time which can affect accuracy. An analytical balance is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. This enclosure is often called a draft shield. The use of a mechanically vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the measure of mass down to 1 μg without fluctuations or loss of product. Also, the sample must be at room temperature to prevent natural convection from forming air currents inside the enclosure from causing an error in reading. Single-pan mechanical substitution balance maintains consistent response throughout the useful capacity is achieved by maintaining a constant load on the balance beam, thus the fulcrum, by subtracting mass on the same side of the beam to which the sample is added. Aluminum, mass-produced balance scale (steelyard balance) sold and used throughout China: the scale can be inverted and held by the larger ring beneath the user's right hand to produce greater leverage for heavier loads ( Hainan, China)

Resolution – this is the value which shows how close the scale can read to the object’s actual weight. For instance, a scale could have a resolution of one gram, which means if an object weighs 20g the scale will give a reading up to one gram either way from the object’s true weight. Unlike spring-based scales, balances are used for the precision measurement of mass as their accuracy is not affected by variations in the local gravitational field. (On Earth, for example, these can amount to ±0.5% between locations.) A change in the strength of the gravitational field caused by moving the balance does not change the measured mass, because the moments of force on either side of the beam are affected equally. A balance will render an accurate measurement of mass at any location experiencing a constant gravity or acceleration.When the Berg balance scale was created in 1989, it was intended to assess both balance and fall risk. However, research throughout the years has shown that the test is a poor predictor of falls. Therefore, today the BBS is generally used to assess static balance (the ability to keep your body in a fixed posture). If your healthcare provider’s goal is to determine your fall risk, the BBS may be performed in combination with other assessments, while taking your unique situation into account. Who performs the Berg balance scale? To get a better understanding of how scales operate, it helps to know about mass and weight. Difference between mass and weight: Even new scales can become inaccurate in certain conditions, particularly in extreme temperatures. For this reason, the most accurate scales offer high temperature stability. Traditionally, a weighing scale was a device that displayed weight by measuring a deflection, such as a spring scale. In modern weighing machines, scales generally use springs or strain gauge load cells. How do scales work?
