Computer-Aided Coulometric Control System

Several versions of a multifunctional computer-aided system for experimental high-temperature electrochemistry, each differing in platform (type of operational system—Windows, Real-time Linux; input–output cards; the availability of digital signal processors on these cards; etc.), are described. For each version, the comparative accuracy and time characteristics of the operation of the system's coulometric channel are given and ways to attain them are described. Advantages of the system include the possibility of real-time operation in a wide range of parameters (the interval between measurements runs from 4 × 10–7 to 1 s, while the response time to external events runs from 0.8 to 60 μs), the possibility of high-precision measurements of the amount of electricity passed through an electrochemical object (the minimum limit for measuring the amount of electricity is 1 μC with a basic error of 0.1%), the automatic generation of control commands; and its applications for research, industrial, and experimental purposes.
