6. CO digital gas transmitter is used for detection of carbon monoxide in the ambient air to monitor the presence of carbon monoxide gas 2 Function description The sensor portion of the PolyGard DT 1110 digital gas transmitter is a micro fuel cell which is completely sealed The measurement is a gas in liquid chemical reaction rather than a surface area measurement With no surface area to coat this sensor retains its sensitivity to carbon monoxide even after prolonged exposure to clean air The cell consists of a diffusion barrier O ring seal electrolyte reservoir and two electrodes sensing and counter The target gas carbon monoxide enters the cell through a diffusion barrier The chemical process of the measurement is one of oxidation 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 counter electrodes The amount of electrons produced by the reaction is directly proportional to the amount of gas present and measuring the current flowing through the external circuit is a basic gas monitor The integrated amplifier circuit and ADC converts this DC microampere signal to a digital signal with a ppm range For the interoperable communication this value is written in the Standard Network Variable SNVT nvo01_TOX Most sensors produce a small amount of baseline current in clean air This is adjuste
