Measurement and control Digital instruments and measuring transducers

Digital instruments and measuring transducers Digital instruments and measuring transducers CIRCUTOR offers a wide range of fully programmable digital indicators and instruments that can be used to display electrical parameters or define an alarm system associated to an electrical pa-rameter. Dͩfinition In digital instruments, the measurement process provides discontinuous information, expressed in a number with var-ious digits. This is the numerical value of the parameter measured; the numerical indication is presented throughout the time scale with a predetermined fre-quency. In general,...
