Load cell with a weighing range up to 1 kg

Kibble balances weigh using a voice coil actuator with electromagnetic force compensation. For the calibration of Kibble balances with a larger measuring range (from grams to kilograms), optical methods are used. A new method developed at PTB allows the correction of errors caused by tilting mirrors, the so-called Abbe errors. This calibration procedure has been tested at PTB and can also be used for other applications where the Abbe error occurs. (Technology Offer 538)
