Dew point transmitters play a critical role in industrial drying applications across various sectors, ensuring high-quality compressed air and optimal environmental conditions for manufacturing processes. The following case studies highlight their importance in different industries, demonstrating how dew point monitoring can safeguard equipment, enhance product quality, and prevent operational disruptions.


In refrigerated air dryers, dew point monitoring helps protect pneumatic equipment by ensuring clean, dry compressed air. These dryers use freezing and dehumidification to remove moisture, and dew point sensors are essential for maintaining air quality, with typical requirements ranging from -20°C to -40°C. Moisture in the air can damage pneumatic components like control valves and cylinders, leading to equipment failure. Thus, monitoring dew point helps ensure the safe operation of factories, safeguarding both machinery and production processes.


Similarly, in adsorption dryers, which use materials like molecular sieves to absorb moisture, dew point monitoring ensures the compressed air is dry enough for sensitive applications. In industries like electronics manufacturing, where compressed air contacts electronic components, a dew point range of -40°C to -60°C is crucial to prevent moisture from damaging delicate parts. Medical equipment also relies on low-humidity air to prevent microbial growth, with a dew point requirement of -27°C to ensure air quality meets strict standards.


In lithium battery factories, where moisture can damage the battery’s internal components, precise dew point control is vital. The drying of electrode plates, which requires low humidity, is especially sensitive, and manufacturers often require a dew point below -40°C during the drying process. Dew point sensors installed in tunnel dryers allow real-time monitoring, ensuring optimal environmental conditions and minimizing risks to product quality and safety.


Thermal power plants also depend on dew point monitoring to maintain stable combustion. High humidity can disrupt the ignition process and lead to power generation failures. By installing dew point transmitters at air compressor outlets, power plants can ensure that only low-humidity air is supplied to the combustion system, preventing operational disruptions and maintaining efficient power generation.


In all these applications, the use of high-precision dew point transmitters, such as the PCD03 sensor, ensures that industrial drying systems operate at peak efficiency, maintaining air quality and safeguarding both equipment and production processes across various sectors.
