The amount of displacement occurred can be calculated using the various displacement transducers, and thus force measurement can be done.This is an indirect method for calculating force. The basic idea of this method is to use the uncertainty ranges of each variable to calculate the maximum and minimum values of the function.

Ammeter- voltmeter method; Potentiometer method; Kelvin double bridge method; Ohm-meter method To avoid the regular use of very long numbers, SI (the international system of units) encourages the use of multiples of 1 000, (expressed as 103 in scientific notation) for large numbers, and multiples of 0.001 (or 10-3) for small numbers. Torque is determined indirectly through measurement of certain auxiliaryquantities in the drive train. ): Instrument Engineers’ Handbook: Process Measurement and Analysis, 4th edn., pp. If you have any questions about your favorite products or solutions, please contact us.

It is defined as Mass x Acceleration = Force. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. In Japan,  “N・m” and “N・cm” are allowed to use in torque measurement due to Measurement Act of Japan. 2.1), which can use various measurement principles or methods. In a broad sense, load cells and force-sensitive resistors (like FlexiForce touch sensors) are the two most common methods.
