Specifications 

CY7200A1002 
 

CO concentration transmitter (4 to 20 
mA, 1 to 60 ppm)   

 

Measurement Principle 

(Constant-potential electrolytic method)

 

When gas is electrolyzed while maintaining potential be-
tween electrodes immersed in electrolyte, the current 
assumes values proportional to the gas concentration.   
Because the electric potential at which electrolysis takes 
place depends on the gas, only CO concentration is 
measured.    CO concentration is, therefore, obtained 
from the potential.
