whats the principle & science is beyond this,How O2 sensor
sence & convert signal & move toward analyzer & analyzer
show reading in percent?
Answer Posted / arun kr
An electro-galvanic fuel cell is an electrical device, one
form of which is commonly used to measure the concentration
of oxygen gas in scuba diving and medical equipment.
A chemical reaction occurs in the fuel cell when the
potassium hydroxide in the cell comes into contact with
oxygen. This creates an electric current between the lead
anode and the gold-plated cathode through a load
resistance. The current produced is proportional to the
concentration of oxygen present.
