DISTRIBUTED AUTOMATIC LEAK TESTING CONTROL SYSTEM

摘要

Most of the chemical-technological processes are extremely dangerous. Conventional monitoring systems based on stationary gas analyzers do not give information about where medium leaks from. This report describes a new way of constructing automatic system for potentially dangerous medium leakage localization at the actuating production lines. Design concept of automatic leakage's monitoring and control system with the distributed network structure are considered. The information channel works out at one-chipped base with semiconductor gas-sensitive element. Diminutireness (1sm~3), low power consumimg (<1W), high sensitivites (1ppm), fast response (1s) and low cost allow to mount sensors of this type closely to potential dangerous technological communications (stuffing-boxes, flanges and etc.). These systems provide high alarms and gas leakeges localization with sufficient accuracy.
