What Is a Dewpoint Transmitter?
A dewpoint transmitter is a type of hygrometer that measures the amount of moisture in the air and outputs it as the dewpoint temperature.
Dewpoint transmitters operate based on two main principles: the mirror cooling method and the polymer sensor method. The mirror cooling method measures the condensation temperature by cooling a metallic mirror, while the polymer sensor method absorbs moisture and converts its change into the dew point temperature.
It is used in various fields such as manufacturing, the energy sector, environmental monitoring, medical devices, and research and development. This device consists of sensors, thermometers, signal processing units, and display units, allowing for more precise measurement of moisture content by measuring dewpoint temperature rather than humidity. Key features of dewpoint transmitters include precise moisture measurement, applicability to various uses, and the maintenance of polymer sensor-based systems.
