Sensor Electronics Corp., Minneapolis, MN, offers a system that couples an SEC 3000 toxic gas sensor with an SEC 3100 transmitter to provide toxic gas monitoring for semiconductor production areas. The transmitter incorporates a plug-in memory stick that logs a permanent record of actual gas levels, remembering times, concentrations, trouble signals, and service interruptions and can be used to download data to a computer for retrieval and analysis. The transmitter's display shows actual gas levels and color-coded LEDs to reflect gas concentrations and warn of troubles. At a setpoint, integral relays can trigger alarms, turn on supply/exhaust fans, and shut down lines.
