• This paper describes the development of a nonlinear resistance unit simulating viscous flow conductance which uses a dual-cell optocoupler. The resistance of this VFS (viscous flow simulation) unit varies from 3 kΩ to 30 MΩ and is inversely proportional to the mean voltage applied to the unit. By connecting a VFS unit and an ordinary fixed resistor in parallel, the conductance of a long circular pipe was simulated in a wide range from molecular flow to viscous flow. The response time of the unit was 2 ms for turn-on and 17 ms for turn-off. A multistage vacuum system was simulated with several VFS units and the results are compared with the numerically-calculated values.
