Industrial processes often involve extreme temperatures and humidity levels. Regular transmitters can’t handle these harsh conditions. Here’s a breakdown of applications where high-temperature and humidity transmitters (operating over 200°C and down to -50°C) are crucial:
Here is a structured table for the applications of high-temperature and low-temperature transmitters in extreme environments:
| Zastosowanie | Opis |
|---|---|
| High-Temperature Applications (Over 200°C) | Industrial Ovens and Furnaces: Monitoring temperature and humidity is vital in curing processes like painting, drying ceramics, and heat treating metals. Precise control ensures product quality and prevents defects. |
| Power Generation: Humidity measurement in power plants helps prevent corrosion in turbines and other equipment exposed to high temperatures and steam. | |
| Przetwarzanie chemiczne: Accurate temperature and humidity data is essential for safe and efficient chemical reactions in reactors, dryers, and pipelines. Deviations can lead to hazardous situations or product contamination. | |
| Produkcja półprzewodników: Creating microchips involves tightly controlled environments with high temperatures and low humidity. Transmitters ensure proper conditions for sensitive processes like photolithography and etching. | |
| Glass Manufacturing: Glass production requires precise temperature and humidity control during melting, blowing, and annealing. Transmitters help maintain consistent glass quality and prevent defects. | |
| Low-Temperature Applications (Down to -50°C) | Cold Storage Facilities: Monitoring temperature and humidity in freezers and cold warehouses helps maintain optimal conditions for food preservation and prevent spoilage. |
| Cryogenic Applications: Extremely low temperatures are used in research and industrial processes like superconductivity and liquefied natural gas (LNG) storage. Transmitters ensure safe handling and prevent equipment damage from ice formation. | |
| Climate Monitoring: These transmitters are valuable tools for weather stations in extreme cold environments like the Arctic or high mountain regions. They provide accurate data for climate research and weather forecasting. | |
| Aerospace Industry: Testing aircraft components for functionality in frigid conditions requires precise temperature and humidity control. Transmitters simulate real-world scenarios and ensure aircraft safety. | |
| Wind Turbine Icing: Detecting and measuring ice formation on wind turbine blades is crucial for safe operation. Transmitters help prevent blade damage and power generation loss in cold climates. |
