Related Knowledge Of Zirconia Insert

    Zirconia (metal compound) is a solid electrolyte. People doped with a certain two yttrium oxide and other impurities, in high temperature conditions (T> 600 ℃), it will become a good oxygen ion conductor. Zirconia sensor (also known as the probe) is based on this principle produced. Zirconia detector for the straight tubular structure, zircon tube at the end of the platinum electrode and external power of the sensor. When the oxygen concentration inside and outside the zirconium tube is different, the probe will produce a potential difference. The method of measuring the potential can be used to know the percentage of oxygen in the measured gas.Zirconia Insert

    Technical Specifications.Zirconia Insert

    Measurements: Oxygen concentration (vol%) in the combustion of exhaust gases and mixtures (except for flammable gases, which can not be used for corrosive gases such as ammonia, with YOKOGAWA)

    Measuring system: Zirconia system Oxygen concentration: 0.01 ~ 100 vol% O2 Output signal: 4 ~ 20mA DC (maximum load resistance 550Ω)

    Measuring range: 0 ~ 5 to 0 ~ 100 vol% O2 (1 vol% O2) within the arbitrary set, or set the local range. Digital communication (HART): 250 to 550Ω, depending on the number of field devices in the connection loop (multipoint mode). Note: HART is a registered trademark of HART Communication Foundation.

    Display range: 0 ~ 100 vol% O2 Heating time: about 20min.Zirconia Insert

    Repeatability: (except for natural convection air as reference gas) Set ± 0.5 vol% of the maximum range. (Range of 0 to 25 vol% O2)

    Set the maximum range of ± 1 vol%. (Range from 0 to 25% to 0 to 100 vol% O2)

    Linearity: except for standard gas error (except when natural convective air is used as reference gas) (using gas at known oxygen concentration (within the measuring range) as zero gas and range calibration gas)Zirconia Insert

    Set the maximum range of ± 1 vol%. (0 to 5 to 0 to 25 vol% O2) (sample gas pressure: within ± 4.9 kPa)

    Set ± 3 vol% of the maximum range. (0 to 25 to 0 vol% O2) (sample gas pressure: within ± 0.49 kPa)

    Set the maximum ± 5 vol% of the range. (0 to 50 to 0 to 100 vol% O2) (sample gas pressure: within ± 0.49 kPa)

    Drift: (except for the first two weeks of the start) (except when natural convection air is used as reference gas)

    Zero and span are set to ± 2% of the maximum range of the range Response time: 90% response within 5 seconds. (Measured when the gas enters the calibration gas inlet and the analog signal starts to change.)
