Automated switch for multiple gas-analyzer lines

By Chemical Engineering |

Up to now, solenoid valves have been used for switching between lines used for measuring gases, but a considerable effort is required for servicing such arrangements in the event of a failure. This company has developed an alternative — a new, automated measuring-point switch (photo). These point switches can be used in enclosed spaces, such as cleanrooms, and are located upstream of the gas analyzers. The switch can monitor 8, 10 or 16 measuring points. The device clocks all active sampling boxes with a pre-defined interval. In the event of an alarm, the measuring points can be switched manually or individually in order to determine the exact location of the gas emission. The automated measuring switch is equipped so that eight measuring-point changeover switches can be connected to each other. — EM-Technik GmbH, Maxdorf, Germany
