Description
The aSENSE™-GH sensor measures both temperature and carbon dioxide content in the surrounding air, converts the obtained data into an analog or digital signal, and transmits it to the control system.
aSENSE™-GH is a fully digital, low-cost converter designed for installation in climate-controlled zones. A special coating on the printed circuit board and additional filters protecting the device from dust and moisture make aSENSE™-GH ideal for use in greenhouses, mushroom farms, incubators, and other similar applications.
Advantages
- Modern non-dispersive infrared (NDIR) CO2 measurement technology
- Maintenance-free under standard conditions
- Membrane-covered measuring chamber ensures stability, reliability, and accuracy of the carbon dioxide sensor
- Reliable and accurate built-in thermistor for temperature measurement
- Special full coating of the printed circuit board and filter make aSENSE™-GH resistant to dust and moisture
- 2 programmable output signals 0/2-10 VDC and/or 0/4-20 mA for connection to a remote central computer
- Optional RS485 digital interface for data transmission to PC and complex control systems
