A force gauge (also force meter) is a measuring instrument used to measure forces. Applications exist in research and development, laboratory, quality, production and field environment. There are two kinds of force gauges today: mechanical and digital force gauges. Force Gauges usually measure pressure in stress increments and other dependent human factors.
Mechanical force gauges
A common mechanical force scale, known as the spring scale, features a hook and a spring that attach to an object and measure the amount of force exerted on the spring in order to extend it. Another example is the mechanical strain gauge.
An example of a digital force gauge is a load cell (this is often combined with software and a display). A load cell is an electronic device that is used to convert a force into an electrical signal. Through a mechanical arrangement, the force being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals. The software and electronics of the force gauge convert the voltage of the load cell into a force value that is displayed on the instrument.
Test units of force measurements are most commonly newtons or pounds. The peak force is the most common result in force testing applications, this can be used to determine if a part is good or not. Some examples of force measurements include door latch, quality of spring, wire testing, and strength. More complicated tests can also be performed such as peeling, friction, and texture.
