Obtained Class Ⅻ, the world’s highest standard of EU's Measuring Instrument Directive (MID)
Causes of a decline in weighing stability include a change in room temperature and thermal expansion caused by mechanism elements inside a weighcell. To comply with OIML R51 requirements, Anritsu conducted 3D CAD simulation analysis to halve weight value fluctuations caused by a change in room temperature, compared with its previous model. Anritsu also renewed signal processing to not only to quadruple output resolution compared with its previous model but also to improve rejection accuracy to achieve.
Measuring Instruments Directive defines several different classes according to the accuracy of measurement instruments. Anritsu KWS60 series checkweigher is the world's first checkweigher to obtain Class XⅡ, the highest standard ever achieved, with its superior weighing properties. Anritsu's new electromagnetic force balance scale has achieved the verification scale interval of e=0.05 g (3 to 100 g capacity).
