Nernst 1231High precision, long-life, maintenance free heated zirconia probes play an important role in the field of industrial oxygen measurement due to their excellent measurement accuracy, rapid response capability, and long service life. To ensure optimal performance at all times, the following will provide a detailed explanation of the high-precision maintenance method for this probe.

Strictly control the installation process

Correct installation is the foundation for the stable operation of the probe in the future. Adopting a spiral installation method, drill holes at the required installation location, install fixing nuts or flanges, and then screw the probe in. During installation, it is essential to ensure that there are15 - 20The inclination angle of degrees helps prevent condensation from accumulating and causing damage to the probe. When the probe length exceeds1When measuring, it is necessary to install an internal fixing device to ensure the stability of the probe and avoid loosening due to vibration or airflow, which may affect the measurement accuracy.

Regularly clean and prevent blockages

In harsh industrial environments, high levels of moisture and dust are common problems.NernstAlthough zirconia probes have corrosion resistance and can be used normally in these environments, dust and dirt may still accumulate on the probe surface and filter after long-term operation. Therefore, it is necessary to regularly clean the probe and gently wipe the surface of the probe with a soft cleaning tool to avoid scratching. For filters, compressed air blowing or cleaning with suitable cleaning agents can be used to ensure smooth gas circulation and prevent measurement errors caused by blockage.

Reasonably set and monitor temperature

The probe comes with a heater, which can keep the temperature of the zirconium head constant within a suitable range, which is the key to ensuring measurement accuracy. Regularly check the working status of the heater to ensure that it can heat normally and maintain the rated temperature. Meanwhile, closely monitor the temperature of the applied flue gas, and this probe is suitable for0 - 900℃The range of smoke measurement should avoid the smoke temperature exceeding this range, so as not to cause thermal shock to the probe, affecting its performance and service life.

Simple calibration ensures accuracy

NernstThe calibration method for zirconia probes is simple and can be calibrated with air. After the initial installation of the system is stable, it should be calibrated regularly (with intervals determined based on actual usage), using the oxygen content in the air as a reference to adjust the measurement parameters of the probe to ensure measurement accuracy. During verification, follow the correct operating procedures to avoid introducing errors due to improper operation.

Component replacement and maintenance

Each component of the probe can be independently disassembled and replaced. When a component is damaged or its performance deteriorates, it should be replaced in a timely manner. Zirconium batteries have a lifespan of continuous operation4 - 6Years, but intermittent operation will affect its lifespan. If abnormal battery performance is found, a new battery should be replaced in a timely manner to ensure the normal operation of the probe.

By using the above high-precision maintenance methods, we can ensureNernstZirconia probes always maintain optimal performance, providing accurate and reliable oxygen measurement data for industrial production.
