HG808-D High Temperature Dew Point Transmitter
The HG808-D is an industrial-grade temperature, humidity, and dew point transmitter designed for harsh environments with high temperatures even over 90℃. In addition to measuring and transmitting temperature and humidity, the HG808 calculates and transmits the dew point, which is the temperature at which air becomes saturated with water vapor and condensation begins to form.
Here’s a breakdown of the key features:
▪ Integriertes Design, einfach und elegant
Industrietauglicher ESD-Schutz und verpolungssicheres Design der Stromversorgung
▪ Verwendung von wasser- und staubdichten sowie hochtemperaturbeständigen Sonden
Empfindlicher wasserdichter und feinstaubgeschützter Hochtemperaturfühler
▪Standard RS485 Modbus RTU Kommunikationsprotokoll
The ability to measure dew point makes the HG808 ideal for applications where moisture control is critical, such as:
By measuring and transmitting all three values (temperature, humidity, and dew point), the HG808 provides a comprehensive picture of moisture conditions in harsh environments.

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:
| Anmeldung | Beschreibung |
|---|---|
| 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. | |
| Chemische Verarbeitung: 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. | |
| Herstellung von Halbleitern: 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. |
