Air separation is an industrial process that uses physical methods to separate the main components of air (nitrogen, oxygen, argon) to obtain high-purity gas products. Monitoring the quality and purity of the gas separated from air and the parameters during the process is crucial. The stability, efficiency, and safety of the process from air compression, purification, distillation to the storage and transportation of final products (oxygen, nitrogen, argon, etc.) highly depend on reliable and accurate instrument measurements.

• Temperature difference environment,The air separation process involves cryogenic media ranging from ambient temperature to as low as -196 ℃, and the wide temperature range poses a severe challenge to the stability and accuracy of measuring instruments under different conditions.
• High pressure/ultra-high pressure operating conditions,The operating pressure range of the system is wide, ranging from atmospheric pressure to tens of megapascals, with high and even ultra-high pressure conditions coexisting, posing a severe test on the sealing integrity and pressure resistance performance of the sensors.
• The high requirements for purity and dew point,Minor fluctuations in product gas purity may affect downstream applications such as semiconductors and healthcare. The moisture and impurity content must be continuously and accurately monitored.
• High purity oxygen and strong oxidizing medium,The presence of high-purity oxygen and other strong oxidizing media requires high compatibility of instrument materials and involves potential fire and explosion risks, requiring equipment to have intrinsic safety design.
• Strict ultra-high purity standards require strict control of trace amounts of moisture, hydrocarbons, and other impurities in the gas at ppm or even ppb levels to ensure product quality, with high requirements for detection sensitivity and accuracy.
