Functions and installation precautions of zirconia oxygen analyzer

Abstract: The information on the functions and installation precautions of the zirconia oxygen analyzer is provided by the excellent flowmeter and flowmeter manufacturers. 1. Functions of LT-ZO Zirconia Oxygen Analyzer: 1. Independent compensation and adjustment of zero point and span (advanced function) Generally, the analyzer only has zero point compensation, without span compensation. This makes it difficult to debug the zero point and range, that is, after the zero point adjustment is accurate. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the functions and installation precautions of the zirconia oxygen analyzer. 1. Functions of LT-ZO zirconia oxygen analyzer: 1. Independent compensation adjustment of zero point and span (advanced function) Generally, the analyzer only has zero point compensation, without span compensation. This makes it difficult to debug the zero point and the span, that is, after the zero point adjustment is accurate, the span cannot be adjusted. Or after the range adjustment is accurate, the zero point cannot be adjusted. cause debugging errors. The zirconia oxygen analyzer has independent compensation adjustment for zero point and span, that is, after the zero point adjustment is accurate, the span can also be adjusted accurately. This improves the measurement accuracy of the analyzer. 2. Burnout protection (advanced function) The general analyzer does not have this function. It will cause damage to the furnace. The zirconia oxygen analyzer has this function, that is, when the galvanic couple is disconnected, it will automatically stop heating. It is beneficial to protect the electric furnace. 3. Program temperature heating (advanced function): General analyzer: direct heating method is adopted, that is, it only takes about 5 minutes to heat from room temperature to 700 degrees. Due to the fast heating speed, the speed of hot and cold changes will be fast, which will lead to zirconia. The sensor is broken. The zirconia oxygen analyzer adopts programmed heating, that is, the CPU chip controls the heating rate, about 25 degrees per minute. This ensures that the zirconia sensor is heated to 700 degrees at a constant speed. It is beneficial to ensure the service life of the sensor. 4. Temperature compensation (advanced function) Generally, the analyzer does not have the function of temperature compensation. That is, the ambient temperature in winter and summer is different, resulting in a heating temperature error, which seriously affects the measurement accuracy. Zirconia oxygen analyzer adopts AD590 temperature compensation function. That is, the error caused by the ambient temperature can be automatically corrected in winter or summer, which is beneficial to improve the measurement accuracy of the analyzer. 2. Precautions for the installation of the zirconia oxygen analyzer: 1. After the oxygen probe is used for 8-10 months, it is best to re-calibrate it to determine the background value. If there is no calibration gas, it is determined by the above method. Standard gas calibration, 2. The main component of the oxygen analyzer is an integrated circuit, and the operating temperature of the integrated circuit cannot exceed 55 ℃, so the installation position of the oxygen analyzer should be selected in a ventilated and shaded place, where the rain cannot be exposed, and the ambient temperature cannot exceed 50 ℃ place. 3. The zirconia probe must be inserted into the flue slowly during installation to prevent the zirconium tube from bursting due to sudden high temperature; there are two air inlets on the oxygen probe junction box, which must face downward, and one air inlet is the reference gas. The inlet is normally open and cannot be blocked; the other air inlet is the standard gas inlet, which is normally closed and must be blocked after the test to ensure the measurement accuracy. 4. The oxygen probe must be installed between the flange and the flange. Pad with asbestos, there should be no air leakage, so as not to affect the measurement accuracy; the bottom of the oxygen probe is equipped with a white filter, which will accumulate dust over time and affect the gas penetration, so it must be replaced in time. So be prepared before running It is necessary to do the preparatory work in advance to facilitate future measurements. The so-called sharpening a knife does not cut firewood by mistake. I hope the above introduction can help you, and you are welcome to buy products from our company. The above is the whole content of this article.
