10. ansmitter is a sealed electro chemical cell with three electrodes sensing counter and reference The ambient air to be monitored diffuses through a membrane filter into the liquid electrolyte of the sensor The chemical process of the measurement is one of reduction where one molecule of the target gas is exchanged for one molecule of oxygen The reaction drives the oxygen molecule to the counter electrode generating a DC microampere signal between the sensing and reference electrodes This signal is linear to the volume concentration of the sensed gas The signal is evaluated by the connected amplifier and transformed into a linear output signal Electrochemical processes always lead by and by to a loss of sensitivity Therefore regular calibration of zero point and gain is obligatory See also section 6 Caution There is a small quantity of corrosive liquid in the sensor element If in case of damage persons or objects touch the liquid you have to clean the affected areas as fast and carefully as possible with tap water Out of use sensors must be disposed in the same way as batteries PolyGard is a registered trademark of MSR Electronic GmbH GAADT531193 E 1011 d relevant 12700 Stowe Drive Suite 100 Poway CA 92064 Ph 858 578 7887 amp 888 GO INTEC relevantsolutions com inteccontrols AT 1193 UserManual INEL Specifications subject to change without notice USA 160104 Page 40f 13 CONTROLS 3
