Manufacturing Excellence Since 1931
We often don’t think about the effects that relative humidity can have. It doesn’t stand out the way that the temperature of a room does, where a person might have to turn on a fan or turn up a heater. In fact, relative humidity is crucial to promoting good indoor air quality and is important to the health and safety of several different applications and areas.
Dwyer Instruments offers a multitude of sensors for monitoring air velocity in HVAC systems. Some of this instrumentation has a simple construction (Pitot tubes, for example) while others are more complex, such as hot-wire anemometers.
The initial term and first “hot-wire anemometer” was developed back in 1914 by Louie Vesso King. He is also accredited for King’s Law, which mathematically describes heat transfer in air flows using a heated wire. As the air moves over the wire, it causes a loss of temperature in the wire and removes some of the wire’s heat energy. Continue reading “The Basics of Air Velocity Sensors”
As weather gets cooler, it’s a common misconception that cold and flu viruses are more frequent due to the temperatures outside. This can actually be attributed to the fact that we are inside more, thus being exposed to higher concentrations of pollutants. Poor indoor air quality can cause what has come to be known as sick building syndrome.
