New standard measuring device for small forces
PTB offers calibrations in the Micronewton range
Measuring instruments which measure and generate very small forces are used with increasing frequency in industrial production. Examples are measuring probes which - together with actuators - are also used for assembly. Other fields of applications are, for example, medical products such as insulin pumps and functional catheters. To offer traceable calibrations for these measuring instruments in future as a service to industry, PTB has put into operation a new facility. It again decisively extends the measurement range which, with the available force standard machines, has so far covered a range from 0.5 N to 16.5 MN. For traceability, modern electromagnetically compensated load cells are used instead of conventional loads. This allows force transducers to be calibrated with known measurement uncertainty in the range from 1 mN to 2 N.
