Various Types of Transducers for Weighing, electrical signal, which on further processing indicates the mass of the body. Such a transducer normally requires more frequent calibration against the standard weight of known mass. The following transducers are being considered in this chapter.

Book 2019Latest editionerms of Planck’s constant. The necessity of defining the kilogram in terms of physical constants was already underscored in the first edition. However, the kilogram can also be defined in terms of Avogadro’s number, using a collection of ions of heavy elements, by the levitation method, or using vol

Group Weighing Method,o methods of calibration of weights. Value of a weight of unknown mass may be determined by comparing it with a mass standard of known value. This method is called as one to one comparison method. The second one is to take a group of weights and compare it against a standard of suitable nominal value.

,Nanotechnology for Detection of Small Mass Difference,normal method of using a balance will not do for mass measurement on the microscopic scale. Measurement of mass at the microscopic scale is very vital as it serves powerful tool that can provide information about the molecular and atomic composition of an object, detection, prevention and treatment of various diseases.
