- Transmitters for Fixed Gas Detection Systems



Industry proven performance combined with a new, low-profile design make the Industrial Scientific AirAware a logical choice for those critical areas that require continuous monitoring but not the environmental protection of an explosion-proof enclosure. Providing discrete monitoring and enhanced aesthetics for more commercial or institutional settings, the AirAware Series is the ideal solution for reliable, low-cost fixed-point monitoring.

The AirAware can be configured to operate as a monitor with local LED display, a controller with onboard relay switching capability, a transmitter with 4-20 mA or ModBus RTU outputs, or as a transmitter with on-board relays. Each configuration is designed to meet your specific indoor monitoring needs. Every AirAware is equipped with electrochemical sensing technology, dual alarm LEDs, a digital display providing real-time readings, push-button operation and a NEMA 4 type enclosure. When alarm conditions are met, low/high alarm visual indicators alert users to gas hazards.

A number of output options are available that allow the AirAware to communicate to external controllers or control external audible/visual alarms. All AirAware units are ModBus enabled for digital communication back to a PLC or DCS system. An optional 4-20 mA output is also available to connect the AirAware to almost any control device. Relays can also be added to turn on fans or warning sirens, or to shut down a process. Standard operating power is 12-24 VDC for the AirAware, while a 120 VAC power supply option is available for convenient plug-in monitoring applications. Configure your AirAware to match your needs, adding options such as on-board audible alarm for maximum attention, or a vanity plate to hide the display. The AirAware is covered by a one-year warranty and carries CSA approval for non-hazardous locations.
