Force sensors are extensively used in various research and industrial Ÿelds such as monitoring, testing, and manufacturing. Further, it is extremely important to calibrate the static and dynamic errors of sensors in order to improve their accuracy. However, only static calibration methods are available currently. It is easy to generate static forces precisely by using well-calibrated balance weights. However, this has a signiŸcant disadvantage, that is, the absence of a well-established method for generating and measuring dynamic force precisely. If we attempt to measure the dynamic forces acting on a force sensor for calibration, another force sensor with better dynamic properties and more accuracy than the tested sensor becomes necessary, thereby creating inŸnite loop and somewhat nonsensical situation. In this chapter, we introduce a method for calibrating force sensors without using other force sensors.
