APPLICATIONS

Carbon Dioxide Sensors, Transmitters and Controls

Duomo stock many different models for a broad scope of duties. The more common devices are the wall mounted aSense (A) for CO2 detection to the eSense (B) for combined temperature and CO2 detection. Both models are available as wall mounted or duct mounted (C) versions. For detailed advice on the best model to suit your application call our technical support team.

In conjunction with SenseAir, Duomo has developed the CO2 Alarm (D). This is a 230V unit with two alarm thresholds. Each alarm has an associated relay output.

The eSense -FAI has been developed specifically for educational establishments. It has an acoustic alarm and "traffic light" CO2 level indication as shown.

Duomo also supply the SenseLife Tim8 desktop monitor. This unit provides a visual display of the current CO2 level as well as time, date, temperature and relative humidity. Perfect for an office environment, it can be mains powered or connected to a computer via USB.

Areas of Application

Few gases have so varied and unexpected areas of application as Carbon dioxide (CO2). Interest and demand for the gas is on the increase. This is mainly a result of its proving to be the most environmentally friendly alternative to many different hazardous species used in our society. Carbon dioxide, in spite of not being toxic itself, is an insidious gas. It is harmless in small quantities (we exhale CO2) but in high concentrations it is fatal. Because the gas is odourless it cannot be detected without measuring instruments and many fatal accidents have occurred in e.g. beer cellars where beer or carbonated drinks are stored in barrels. New legislation on serving and storing beer and soft drinks are opening big new markets for CO2 - alarms. One big end user of these CO2 alarms, (delivered by a SenseAir® OEM customer) is MacDonald’s.

SenseAir® products can add:

• Energy saving intelligence and comfort added features, to traditional ventilation components like stand-alone fans, exhaust valves, window openers, fresh air supply actuators, etc.

• Process yield and economic outcome in many bio-related processes, such as in greenhouses, mushroom farming, food transportation /storage, chicken hatcheries, incubators, dairying….

Applications for SenseAir® gas sensors:

• Personal safety - in confined spaces where combustion may be present, or gas leakage is possible, such as garages, tunnels, loading docks, public bars and restaurants, burners and kerosene heaters.
• Automotives – refrigerant leakage control, plus HVAC fresh air supply demand sensing.
• Global environmental surveillance – ground and atmospheric CO2 sensing.
• Homeland security.
• Household appliances (kitchen fans, kitchen ranges).
• Healthcare, sports & leisure.

SenseAir® sensors can easily be included as partial systems in larger system solutions. The products can easily be adjusted to comply with differing customer requirements.
