DEVICE FOR MEASUREMENT OF VARIABLE SCALAR QUANTITIES DISTRIBUTED IN SPACE Russian patent published in 2004 - IPC

FIELD: measurement technology.

SUBSTANCE: proposed device includes measurement channels provided with sensors and control unit with control output. Each measurement channel has control input and inverter, change-over member and voltage-to-current converter whose output is connected with output of channel. Control output of control unit is connected to control inputs of channels whose outputs are connected by means of common conductor which performs function of output of device. Inputs of change-over members of one group of channels (50% of channels) are connected with sensors and inputs converters through inverters. Inputs of change-over members of other group of channels are connected to sensors and directly to converter inputs. Groups of channels are formed by means of control unit depending on position of sensors in space being measured according to orthogonal binary function system which take magnitude of plus or minus.

EFFECT: enhanced efficiency of determination of considerable local changes; increased dynamic range of useful signal.
