To be applied between the counter electrode and the cathode polarization voltage, if the measuring element immersed in the water with dissolved oxygen, diffusion of oxygen through the membrane will appear on the cathode (electron excess) oxygen molecules will be reduced to hydroxide ions [OH-]. Electrochemical equivalent of silver chloride deposited on the counter electrode (electron deficiency), for each molecule of oxygen, the cathode emitted electrons 4, the counter electrode accepts electrons, forming a current: 4Ag + 4Cl- = 4AgCl + 4e-. Divided voltage proportional to the measured size of the current oxygen water, the thermal resistance of the sensor signal along with the measured temperature signal from the transmitter sent people use between the sensor and the partial pressure of oxygen stored in the oxygen content, temperature, The curve calculated from the oxygen content in the water, and then converted into a standard signal. The reference electrode is to determine the function of the cathode potential. 9437/0091000] [original] [9437/0091000 9437/0091000 billion Long electromechanical] [original] [9437/0091000 billion Long electromechanical
