Force gauge

A force gauge (also force gage) is a small measuring instrument used across all industries to measure the force during a push or pull test. 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 dependant human factors.[1]

Mechanical force gauges[edit]

A mechanical force scale, commonly 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.[2] e.g. Spring scale, strain gauge

Digital gauge[edit]

A digital force gauge is basically a handheld instrument that contains a load cell, electronic part, 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. It is used to determine if a part is good or not. Some examples of force measurement: door latch, quality of spring, wire testing, strength ... but more complicated tests can be performed like peeling, friction, texture.

  • Metal wire testing
  • Bursting strength testing of cardboards
  • Weld force between electrodes
  • Gun trigger testing
