apart frm electro-galvanic fuel cell, o2 mesrment is also by
zirconia and paramagnetic prnciple,and thus produces mV.

in a analyser ,there b a programming ,which produces the %
accrding to voltage generated due to ionisation

Answer / 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.

If a normal magnetic type flow transmitter that can measure flow, temperature and show this parameters on field, is it possible by any means to get this (flow and temperature) parameters info. On dcs? And if yes then with HART, FO communication or any other communication system?
