The principle and application of zirconia oxygen sensor

Abstract: the principle and application of zirconia oxygen sensor information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. * part of zirconia oxygen sensor working principle, product introduction: zirconia oxygen sensor is to use the zirconia ceramic sensor measurement of all kinds of heating furnace and exhaust pipe the oxygen potential, which is calculated from chemical equilibrium principle corresponding oxygen concentration, to monitor and. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the principle and application of zirconia oxygen sensor article details. * part of zirconia oxygen sensor working principle, product introduction: zirconia oxygen sensor is to use the zirconia ceramic sensor measurement of all kinds of heating furnace and exhaust pipe the oxygen potential, which is calculated from chemical equilibrium principle corresponding oxygen concentration, to monitor and control in furnace combustion air likelihood ratio, to ensure product quality and the exhaust emission standards of the measuring element, is widely applied in all kinds of coal, oil, gas combustion, etc. The atmosphere in the furnace control. It is currently zui better combustion atmosphere measuring way, has a simple structure, quick response, easy maintenance, easy to use, accurate measurement, etc. Using the sensor measurement and control for combustion atmosphere can stabilize and improve product quality, but also shorten the production cycle, save energy. Second, the working principle of the oxygen sensor: oxygen sensor is the use of stable cubic zirconia ceramic in the above 650 ℃ environment produce oxygen ionic conduction properties and design. Under certain conditions of temperature, if in the zirconium dioxide block on either side of the ceramic gas exist in different oxygen partial pressure ( The oxygen concentration) , cubic zirconia ceramic internal will produce a series of reaction, and oxygen ion migration. At this time by zirconium dioxide leads on both sides of the electrode, measurable to stable millivolt level signal, we call it the oxygen potential. It is subject to nernst ( 能斯特) In the equation: E for oxygen sensor output oxygen potential ( mv) , Tk is absolute temperature inside the furnace ( K) , P1 and P2 respectively on both sides of zirconium dioxide gas oxygen partial pressure. Practical application, the side of the zirconium dioxide gas going into the known oxygen concentration ( Usually a air) , we call it a reference gas. On the other side is the gas being measured, it is what we want to test the atmosphere in the furnace, as shown in the figure 1. Oxygen sensor output signal is the oxygen potential signal, we can get through the nernst equation by the relations between the oxygen partial pressure and oxygen potential in the furnace atmosphere. Reference gas for air, can be expressed as: type of E for oxygen sensor output oxygen potential; Tk is absolute temperature inside the furnace; P02 for oxygen partial pressure inside the furnace. Our oxygen sensor products with the heating device, general temperature guarantee at 700 ℃, the TK numerical base is constant, which can be directly measured through the type oxygen partial pressure concentration inside out. Engineering application of standard gas is used to calibrate the oxygen sensor output oxygen potential E and oxygen partial pressure concentration PO2 corresponding relation, this method is currently accepted zui accurate, zui direct calibration method. HMP oxygen sensor structure: the core component of HMP oxygen sensor adopts imported zirconia oxygen sensor ( See figure 2) The zirconia oxygen sensor with intelligent heating device, provide constant voltage control signal can be fast to use temperature, and ensure the sensor under the constant temperature continuous, stable work. Install the probe need to adjust the direction of the guide plate, guide look to airflow direction, so as to form gas from the diversion of detecting atmosphere. Typical performance characteristics are as follows: imports of zirconia oxygen sensor zero error: on & plusmn; 0. 2号; Ac resistance ( 1500 hz) :( 700℃) On 100000; ( 1100℃) On euro 5000. Response time ( 700 - 1300℃) HMP oxygen sensor sampling, maintenance way: HMP oxygen sensor USES the atmosphere since the diversion, import the test atmosphere, consider the environment factor of engineering site, purging clear channel is designed, can easily guide the sampling pipe purging work, in order to avoid dust, coal ash or the pipe inside the furnace, oil impurities and so on blocking sampling tube, please refer to figure 3. Technical performance: using temperature: room temperature to 1100 ℃; The oxygen potential range of display: - 50 ~ 1240 mv; The oxygen potential output precision: & plusmn; 0. 5 mv; Response time: & le; 1 seconds; The service life of the normal use, & ge; 18 months. The third part of the installation of the oxygen sensor installation and reasonable is the key to ensure reliable operation of oxygen sensor, many problems are due to improper installation of the oxygen sensor, hope that the user must pay special attention to this point, oxygen sensor installation, please try to consider oxygen sensor installation requirements: a, sampling points: to determine the measurement point is the primary work.
