Addressable gas monitoring system

ATi’s GasSens Midi Addressable Monitoring system is capable of measuring over 60 different gases or vapours. Supplied ready to use with pre-calibrated gas sensors, ATi’s GasSens Midi has been designed to operate in the full range of environments, from commercial premises through to heavy industrial applications.

Each gas sensor continuously monitors the atmosphere, reporting any hazardous conditions to the control unit for display by the alpha numeric screen, indicating the reporting sensor, gas type, concentration and alarm status. Alarm levels that are exceeded will automatically activate a variety of signal outputs, including analogue/digital data and user selectable relays.

The GasSens Midi system operates on a 4-core cable network and has the capacity to monitor up to 64 addressable sensors. Larger systems offering up to 1,024 sensors can be achieved using multiple Midi units, housed in a 19” rack-based system, or by having a network controller supervising up to 16 Midi units.
