DEVICE FOR MEASURING LINEAR SIZES Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: device for measuring linear sizes has additional counter, two subtracters, two decoders and AND-OR gate. Output of amplitude selector is connected with inputs of first and second permanent storages through additional counter. Outputs of permanent storages are connected with first inputs of first and second subtracters. The second inputs and outputs of subtracters are connected with output of unit for counting marks and with first inputs of first and second decoders. Outputs of decoders are connected with first and second inputs of AND-OR gate. The third input and output of AND-OR gate are connected correspondingly with output of unit for counting number of marks and with first input of indicator.

EFFECT: reduced influence of error of object installation; improved precision of measurement.
