For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of how to select and install ZO series zirconia analyzers. Industrial Oxygen Analyzers For many industrial processes, accurate oxygen measurement is critical. This can be the purity detection of industrial gas, the anti-leakage monitoring of glove box, or the control of the best combustion efficiency of fuel gas. Given that the needs of different applications are often very large, major manufacturers will provide a variety of analyzers to ensure that users can always choose the most suitable technical solution. 1. .ZO series detector 1. Insertion depth selection: furnace wall thickness + 300mm (detector length specifications are 400mm, 600mm, 800mm, 1000mm, 1200mm for selection) 2. Selection of flue gas temperature at installation point: flue gas temperature<700℃, choose ZO standard detector smoke temperature≥700 ℃, choose ZO high temperature detector 2. ZO series zirconia has the following main features: 1. Thermal inertia protection: easy installation, hot installation, and strong adaptability to stop and start furnaces. 2. The sensor uses Japanese ion coating technology, which greatly improves the service life. 3. The zirconia probe adopts full 321 stainless steel (1Cr18Ni9Ti) sheath, which has excellent wear resistance and corrosion resistance. 4. In-line type: no sampling system, fast response, effectively reduce ash blockage in flue gas. 5. Thermal diffusion reference: no need for a special reference air pump, easy to use and maintain. 6. Dual-parameter design: Overcome the discrete performance of domestic zirconia, accurate measurement and prolong service life. 7. Online calibration of working conditions: accurate and reliable, online calibration of single standard gas is convenient, working point can be directly calibrated, and the measurement is accurate. 8. Dual output: It has switch node output and 4-20mA two-speed output at the same time. 9. The components are removable: the components are easy to replace, easy to maintain, and reduce the cost of use. 10. Multi-function display: oxygen content (%); oxygen potential; temperature, and the digital display of background potential parameters are intuitive and convenient. 12. Full floating design: common mode input, strong resistance to electric field interference, no need for special ground wire, easy installation. 13. Large load: 750 ohms/4-20mA, which is convenient for remote installation. 14. The background potential is adjustable, the adjustment range is wide, and the parameters such as component aging can be checked at any time. 15. The zirconia probe adopts full 321 stainless steel (1Cr18Ni9Ti) sheath, which has excellent wear resistance and corrosion resistance. 16. The product series has strong adaptability: it can be applied to various furnace types of gas, oil and coal. The measurement temperature can be selected from room temperature to 1400 degrees to a suitable model. 3. Installation method of ZO series zirconia analyzer (1) Unpacking inspection, check the number of pieces and appearance according to the contents of the packing list (2) Laboratory inspection (A) Detection Check the cold state of the detector, open the junction box of the detector, and measure with the ohm gear of the multimeter. The oxygen battery terminals 1-2 are in an open state, and the resistance value exceeds the range. The resistance value between the thermocouple terminals 3-4 is only a few ohms, which is normal. The resistance value between terminals 7-8 of the electric furnace wire is about 80Ωis normal. Note that measuring the resistance of the electric furnace wire can only be carried out in the power-off state. Use visual inspection between thermocouple compensation terminals 5-6, gently move AD590 by hand or tool, and the lead wire should be fastened on the terminal. (B) Check the thermal state, and connect according to the system wiring diagram 7. After checking, the power is turned on, and the temperature is displayed on the front panel during the heating process. When the temperature rises to 600°C, if the meter is in the measurement state, the program will automatically switch to the oxygen content display state, and the value should be near the air oxygen content of 20.6. If the meter is in the maintenance state, all buttons on the panel can be operated. (a) Qualitative check first step to confirm whether the controlled temperature is 700℃±2 ℃, the general thermal potential is about 28mV, the temperature value of the reference table plus the room temperature should correspond to 700 ℃. The second step is to measure the internal resistance of the oxygen potential with the ohm gear of the multimeter. average value. The internal resistance of the new probe battery is generally less than 100Ω, the old probe should be controlled at 800 after overhaulΩwithin. Note: When using the above method to measure the internal resistance of the battery, the meter should be disconnected from the automatic control system, because the multimeter is active, and there is a signal superimposed on the oxygen potential, which will interfere with the measured oxygen. (b) Quantitative calibration: adjust and operate according to the instrument through standard gas. (3) M12 must be prepared before installation′50 screws, corresponding nuts, washers, washers, and gaskets between flanges, etc. (4) Installation location: (A) The installation of the detector The detector should meet the following conditions: 1. Mechanical vibration should be avoided as much as possible 2. The sampling gas and pressure are within the standard specifications, the furnace body is well sealed, and the detector should be as far away as possible from the smoke. It is installed downstream of the gas to reduce the temperature of the detected gas. In order to create a slight positive pressure, the downstream smoke flow path near the gas intake point is slightly smaller. 3. The ambient temperature is within the standard range 4. The probe should avoid the influence of high radiant heat and high radiant steam 5. Avoid dust and corrosive gases
