aSENSE™ GH
Model aSENSE GH “Green House” is a transmitter for installation in the climate zone. The special coated PCB and extra dust/water protection filter make aSENSE GH suited for all kinds of greenhouses, incubators and similar environments. The unit measures both temperature and carbon dioxide concentration. aSENSE GH measures both temperature and carbon dioxide concentration in the ambient air, transforms the data into digital output signals and sends these values to a comprehensive system. The transmitter measures CO2 concentration in the ambient air up to 3000 ppm and transforms the data into an analogue 0/2-10 V / 4-20mA output signal.
Key benefits
-Measures both temperature and carbon dioxide.
-Resistant towards dust and humidity.
-Analogue outputs 0/2-10 VDC and/or 0/4-20 mA for connection to remote central computer.
-Optional RS485 digital interface to PC and advanced control network system.
-Cost optimized for connection to DDC:s.
Applications
Carbon dioxide is a necessity to all forms of life. It is a vital parameter in the production of all kinds of plant species, bacteria, chicken etc. A natural application for aSENSE - GH is therefore to supervise and/or control the climate in e. g. greenhouses, mushroom farms, agricultural, horticultural and medical incubators based on CO2 concentration and temperature. SenseAir model aSENSE - GH is especially suited for installation in these and similar environments since it measures both temperature and carbon dioxide concentration in one single unit. Both are very important parameters when trying to achieve an optimum growth. Integrated complimentary humidity sensor is available as option.
