Spring scale

The spring balance or dynamometer is an instrument for measuring force, such as the weight of an object. Its origin dates back to the late 17th century, when physicist Isaac Newton devised a measurement tool based on Hooke's Law of Elasticity, which states that the force to elongate a spring is proportional to the length it extends from its base. Resting state.

How does it work?

The dynamometer works by a cylinder contained inside the scale, which houses the spring and has a hook at each end. On the outside, the hollow cylinder that surrounds the spring has a marked scale, so that when a force is exerted on the hook, the cursor will move to indicate the value of the force, that is, the weight.

For what do you use it?

The spring scale is used to measure the weight of silos in agriculture, trucking trucks, railway cars, materials transported on machines using conveyor belts. Its function is to measure weight, calculate the deformation of materials when subjected to great efforts, and know the force applicable to dental treatments, measurement of test tubes in scientific laboratories, among other applications.

Types of dynamometers

Spring scales have also evolved for use in various applications. In general, the measurement range is calculated in newtons and can be converted to kilograms. The types of dynamometers are:

·       Mechanics they are the traditional ones, which are used thanks to their precision since they have an approximate deviation of +/- 0.3% of the load and a tare range of 20%.

·       Electronics. They have a data interface and, in some cases, software to transfer the weight data to the computer.

Mechanical dynamometers are typically used for industrial and commercial applications, while electronic or digital dynamometers are used in research and development.
