| The TGS4160 is a hybrid sensor unit composed of a carbon dioxide sensitive element and a thermistor. A wide range of 350~50,000ppm of carbon dioxide can be detected by TGS4160, making it ideal for usage in a variety of applications. The CO2 sensitive element consists of a solid electrolyte formed between two electrodes, together with a printed heater (Pt) substrate. By monitoring the change in electromotive force (EMF) generated between the two electrodes, it is possible to measure CO2 gas concentration. Adsorbent (zeolite) is filled between the internal cover and the outer cover for the purpose of reducing the influence of interference gases. TGS4160 exhibits a linear relationship between AEMF and CO2 gas concentration on a logarithmic scale. The sensor displays good long term stability and shows excellent durability against the effects of high humidity. | |||||||||||||||||||||||||||||||||||||
| The figure below shows typical humidity dependency for an energized sensor. Again, the Y-axis is indicated as AEMF which is defined as follows: AEMF=EMF1 - EMF2 where EMF1=EMF in 350 ppm CO2 EMF2=EMF in 1000ppm CO2 | |||||||||||||||||||||||||||||||||||||
