Zirconia analysis for many industrial processes, the accurate measurement of oxygen is critical. This can be detected purity industrial gases, may be leak-proof glove box to monitor, may also be of optimum combustion efficiency of the fuel gas control. Given the needs of different applications tend to have large, major manufacturers (Wuxi Lake Lee Factory) will provide a variety of analytical instruments to ensure that users can always choose the most appropriate technical solutions. Contents 1 Overview 2 4 3 Technical Data Sensor Installation Summary for many industrial processes, the precise oxygen measurement is critical. This can be detected purity industrial gases, may be leak-proof glove box to monitor, may also be of optimum combustion efficiency of the fuel gas control. Given the needs of different applications tend to have large, major manufacturers will offer a variety of analytical instruments to ensure that users can always choose the most appropriate technical solutions. For example: Wuxi City Instrument Co., Ltd. Zhou WZ production zirconia oxygen analyzer. Zirconia analyzers are mainly used: inert gas reactor or vessel, argon or nitrogen purification, boiler or incinerator, such as combustion control, gas cylinder filling and canning plants, ship with an inert gas generator, the beer industry Carbon dioxide purity testing, heat treatment and other industrial furnaces. Sensor reference standard built-zirconia sensor (MSRS) zirconia sensor is based on the principle of the solid-state electrochemical cell (using zirconia oxygen concentration difference). Zirconia sandwich was heated to 600 ℃, oxygen ions migrate from the side of higher concentration as compared to the low concentration side. This migration naturally between the ends, generates a potential difference can be used to evaluate the content of oxygen. Zirconia sensor comes with standard metal seal, eliminating the need to pick another standard sample gas. The sensor technology was originally used to measure oxygen levels in volcanic environments, its rugged design is fully capable of withstanding high temperatures and corrosive gases extreme. This feature allows the sensor well applied to the use of high-temperature environments, such as combustion gas analysis, so as to achieve the purpose of energy saving. Technical Specifications Range: 0.01% to 25% oxygen content; accuracy: better than 2% of reading; response time: T90 <15s; Repeatability: ± 0.1%; Stability: May drift no more than 1%; Linearity: better than ± 1%; flow: 0.5m3 / min; measuring temperature: up to 1300 ℃; output: 4-20mA; Alarm: two-way, user adjustable; the way error alarm; power supply: 220VAC, 50/60 Hz; Environmental conditions: 0 ~ + 55 ℃. Installation of a flue gas temperature of the installation point choose to install point should comply with the relevant requirements, in general, low flue gas temperature, long life detectors, flue gas temperature is high, short life. Smoke detectors can not be installed without the flow of the dead, can not be installed in the flue gas flow quickly place (as some of airway bypass expansion chamber). Also requires a smaller flue leak detector easy installation and maintenance, for the medium and small boilers, recommended for installation in front economizer superheater, because the flow of flue gases from the furnace boiler system to the drum, through the superheater, the provincial coal, air preheater, the induced draft fan after recovery treatment from stack emissions. If the measuring point is too close to the furnace flue outlet, because the temperature is too high, the flow rate faster detectors will form the erosion-corrosion stainless steel housing, shortened life; if the measuring point is too biased, due to air leaks in the flue system, will result in higher values ??measured at the point of oxygen, can not accurately reflect the furnace flue gas oxygen. 2, the furnace wall detector fixed flange steel frame made of the transition, the transition frame flange welded directly at the wall of the furnace wall or buried in the furnace wall, but requires airtight firm. Transition frame and the other end flange is designed as a fixed detector, and therefore must match detector fixed flange screw. 3, the detector is installed detector reference gas is supplied by natural air convection, the detector needs mounted horizontally, the reference gas and air interface standard corresponding downward. Detector must be installed between the flange and filled rubber cardboard frame flange transition, in order to avoid air leakage into the flue, affect measurement accuracy.
