NernstZirconia probes are highly favored in the field of industrial oxygen measurement due to their high precision, long lifespan, and maintenance free advantages. However, to fully utilize its performance, proper installation is crucial. The following will provide a detailed introductionNernstAttention to details when installing zirconia probes.

Accurate positioning drilling

Before installation, it is necessary to accurately locate and drill holes at the required installation location according to the size and installation requirements of the probe. The diameter and depth of the borehole should be strictly in accordance with the specifications of the probe to ensure that the probe can be smoothly inserted and firmly fixed. If the borehole is too large, the probe may shake after installation, affecting the measurement accuracy; If the drilling is too small, it may cause the probe to be unable to be inserted or even damaged.

Correctly choose a fixed method

The spiral installation method is adoptedNernstCommon choices for installing zirconia probes. After drilling, install a fixing nut or flange, and then slowly screw the probe in. During the screwing process, it is important to apply even force to avoid damaging the probe threads due to excessive force. At the same time, it is necessary to ensure that the probe is screwed into the appropriate depth to ensure sufficient contact with the measured gas and obtain accurate measurement data.

Ensure appropriate installation angle

During installation, it is essential to ensure that the probe has15 - 20The inclination angle of degrees. The design of this inclination angle is not arbitrary, but has important practical significance. It can effectively prevent condensation water from accumulating on the surface of the probe, avoiding corrosion of the probe or affecting the transmission of measurement signals caused by condensation water. During the installation process, tools such as a spirit level can be used to assist in determining the tilt angle and ensure the accuracy of the installation.

Properly handle long probes

When the probe length exceeds1When measuring, it is necessary to install a fixed device inside the probe. This is because long probes are more prone to shaking when subjected to airflow impact or equipment vibration, which affects measurement accuracy. Installing a fixed device can enhance the stability of the probe, allowing it to maintain accurate measurements in complex working environments. The installation of the fixed device should be firm and reliable, ensuring that the probe will not shift due to external forces.

Pay attention to connection details

The probe comes with its own1.5″BSPorNPTThreads, users need to process the furnace wall matching flange according to the attached diagram in the user manual. During the connection process, ensure that the threaded connection is tight and there is no leakage. At the same time, the sealing material of the connecting part should be selected appropriately to avoid the entry of external air due to poor sealing, which may interfere with the measurement results. In addition, the electrical connection of the probe should also be correct and error free. The connection of the direct plug socket or aviation plug socket should be firm to prevent poor contact.
