Dry-Bulb Temperature (DBT)

Definition - What does Dry-Bulb Temperature (DBT) mean?

Dry-bulb temperature (DBT) is the air temperature measured by an ordinary thermometer that is exposed to the environment and captures atmospheric temperature.

To be able to measure DBT accurately, the thermometer should be exposed freely to the air and protected from various factors such as moisture and radiation. It indicates the heat present in the air that is in direct proportion to the air molecules' average kinetic energy.

Corrosionpedia explains Dry-Bulb Temperature (DBT)

Dry-bulb temperature is considered to be the true thermodynamic temperature, although it is usually mistaken as the air temperature. This can be measured in degrees Fahrenheit, Celsius and Kelvin.

This form of temperature does not signify the moisture levels present in the air, as opposed to wet bulb temperature. Accurate measurement of dry bulb temperature is essential in the field of construction. Prior to designing and constructing a building, the specific climate of the area should be considered.

This type of temperature is in fact one of the most vital climate variables not only in terms of establishing energy efficiency and corrosion prevention, but also human comfort as well.

Through the determination of dry bulb temperature along with other variables, the condition of humid air can be generated which is vital in measuring water vapor and energy levels that contribute to the development of moisture and other corrosive factors.
