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.
