Mechanics and Acoustics

Division 1

Weight, force, velocity, loudness -€“ the mechanical and acoustic quantities are cared for by Division 1. Apart from basic research, testing within the scope of legal metrology is a main task.

Tasks

The Division carries out basic research in the field of mechanical and acoustical measurands. On the basis of the Units and Time Act, standards and standard measuring devices are developed with the aid of which the measurement scales for all relevant mechanical and acoustical measurands such as mass, force, torque, acceleration, flowrate of gases and liquids, sound and ultrasound pressure can be realized with maximum accuracy and disseminated, predominantly to DAkkS laboratories. The tasks of the Division also comprise type examinations and certifications of measuring instruments on the basis of national regulations - such as the Verification Act and the Verification Ordinance - of European Measuring Instruments Directives as well as international recommendations of the OIML. In addition, employees of the Division provide advice in all matters of relevant metrology, assess DAkkS and other calibration and test laboratories and cooperate in the respective national and international committees.

An interactive software package which includes a tutorial and example measurement data has been developed to demonstrate how the deconvolution method can be used to subsequently correct measured ultrasonic signals. This program can also be applied to evaluate one's own measurement data [1]. The intention is to make the technique of signal deconvolution accessible to a broader group of users as a...

PTB has developed a new primary standard for the calibration of gas meters using high-pressure natural gas. In future, the so-called high-pressure comparator will form the top of the traceability chain of the new closed-loop pigsar and, as an integral part of the national traceability chain, will contribute to the reduction of the measurement uncertainty values at the level of dissemination of the...
