Mine supply portable carbon monoxide sensor GTH1000 type carbon monoxide detection alarm GTH500 carbon monoxide sensor carbon monoxide sensor mine-type carbon monoxide alarms knowledge outlined chemical sensor carbon monoxide sensors belong to a chemical sensor. Chemical sensors are composed of two parts: identification system; conduction or switching system. Identification system to a chemical parameters analytes (usually concentration) link up with the conduction system. It has two main functions: selectively play a role with the analyte, the chemical parameters measured can be converted into conduction system generated signal response. Molecular recognition system is to determine the key factors whole chemical sensors. Therefore, the main issue is the choice of chemical sensor research molecular recognition system and how molecular recognition system with a suitable phase continuous conduction system. Conducting chemical sensor system receiving a response signal recognition systems, and through the electrode, or the quality of the optical fiber sensor in the form of changes in the response signal voltage, current or light intensity, and transmitted to the electronic system amplifies or converts the output end, the identification system response signal into the signal analysis as it can detect the amount of analyte in the sample. Chemical carbon monoxide gas sensor sealing structure design, the structure is composed of electrodes, filters, breathable membranes, electrolyte, electrode lead (pin), and other portions of the housing. Carbon monoxide sensor carbon monoxide gas sensor and alarm supporting the use of alarm core sensing element, which is based on the basic principle of constant potential electrolysis. When the carbon monoxide gas diffuses into the sensor, whose output generates a current output, to the alarm of the sampling circuit, serves to chemical energy into electrical energy role. When the gas concentration changes, the gas sensor output current is proportional to the change followed by alarm intermediate circuit switching amplifier output to drive different actuators, complete sound, light, electricity and other detection and alarm functions, and the corresponding The control unit together constitute the environmental detection or monitoring alarm system. The scope of products GTH1000 type carbon monoxide sensor (hereinafter referred to as the sensor) is applicable to all workplaces in the coal mine measuring concentration of carbon monoxide in the air analog sensors, digital display locally in carbon monoxide concentration measurements and output standard signal transmission to the associated equipment. After the explosion of the sensor by the state inspection agencies for online testing, can be used with all types of domestic surveillance system supporting. The basic principle of carbon monoxide sensor carbon monoxide gas through the vent when the housing through permeable membrane diffusion to the working electrode surface at the working electrode catalytic oxidation of carbon monoxide gas occurs on the working electrode. The chemical reaction is: CO + H2O → CO2 + 2H ++ 2e- oxidation reaction of H + ions and electrons on the working electrode, it is transferred to the working electrode through the electrolyte to maintain a certain interval of the electrodes, with water oxygen reduction reaction occurs. The chemical reaction is: 1 / 2O2 + 2H ++ 2e- → H2O Thus, the internal sensor occurs oxidation - reduction of reversible reaction. The chemical reaction is: 2CO + 2O2 → 2CO2 this oxidation - reduction reversible reaction in working electrode and the always happening between the electrodes and a potential difference between the electrodes. However, due to take place on both the electrode reaction will cause the electrode polarization, which makes it difficult to maintain a constant electric potential between the electrodes, and thus limits the carbon monoxide concentration detectable range. In order to maintain constant inter-electrode potential, we added a parameter electrode. In the three-electrode electrochemical gas sensor, whose output is the reaction of the reference electrode and the ratio between the working electrode changes due to the reference electrode does not participate in oxidation or reduction reactions, so it can maintain a constant potential between poles (which is a constant potential), then it changes with change in the potential of the carbon monoxide concentration is directly related. When the gas sensor generates an output current which is proportional to the concentration of the size of the gas. With an external circuit through an electrode lead line measuring sensor output current magnitude, it can detect the concentration of carbon monoxide, and has a wide linear measurement range. Thus, the gas sensor external signal acquisition circuit and the corresponding conversion and output circuit, it is possible to achieve carbon monoxide gas detection and monitoring.
