The amount of humidity in the air can have a good deal to do with how we feel and also effect the machinery we are using every day, especially the sensitive computers, visual and photographical equipment and many business operations and machines to name a few. The humidity is the amount of water vapour in the air, measured by dew point meters and humidity meters.
If the temperature drops below the freezing point, it can cause changes in how the linear motion and seals operate in machinery, especially within motion picture cameras and sensors, by increasing the formation of ice or vapour within the operating systems. This can result in the shutdown or failure of the circuit boards or control panels.
HVAC systems are another place where it is important to measure humidity in order to keep the cooling systems of buildings in working order and not burn out the compressors or motors of the units. By recording and keeping track of the humidity, the controls can be adjusted to compensate for the changes in the humidity and keep the HVAC units operating correctly.
The reason these transmitters are so important is that many of the food, pharmaceuticals, and computer chip manufacturers use them to keep track of the water vapour in the air or food. The latest technology of these sensors uses computer chips to measure over 2000 different values of the humidity in the environment and other factors that could influence the production of the foods, medicine or industrial products.
The meters are used in areas where it is important to identify the amount of water vapour that enters into a part of the manufacturing process, such as using compressed dry air or gaseous mixtures to manufacture the components of seals used in various linear motion devices.
A dew point meter gives an up to date continuous recording of the dew point temperature of a selected target or target area. The dew point meter can be used to record the temperature of gasoline while it is being pumped into the automobile. The variety of dew point meters are all engineered to be utilized in different areas of whichever manufacturing process is required.
One fact to remember when using humidity and dew point meters is that the higher the outside temperature or the temperature of the room the more water vapor will be inside the room or picked up by the meters.
The relative humidity is measured by RH units and that varies with the air or gaseous medium being measured. When combined with the monitors of a computer program, the meters can keep track of a very narrow range of data. This data is usually used in technology that requires very delicate and limited ranges of tolerance in the air or gaseous quality; for example as regulating the water vapor as parts per hundred, million or even billion.
The use of both types of measuring systems is useful in determining if there is dangerous weather in the next few days. As the outside temperature rises, the amount of water vapor can contribute to the chance of tornados developing. This is useful when considering the weather forecast that would be in place when the space shuttle lifts off, for example.
In addition to the technology uses, they are used to measure humidity in the air in the world famous museums, to protect and preserve priceless artifacts from damage. Photographic collections can also be affected by the increases in humidity. Photographers use the instruments to also keep their equipment safe, as the condensation of the interior of an expensive camera can be costly.
