What is an air velocity sensor?
Air velocity sensors are ideal for providing real-time feedback in air cooled systems when flow verification is key to maintaining a stable and reliable operation. With an air velocity sensor, hardware issues like fan failures can be quickly identified before critical electronic components overheat.
How does air velocity work?
This tells us that air velocity may be determined by differences in pressure or temperature. Molecules move from spaces of high pressure and high temperature towards spaces of lower temperature and lower pressure. The greater the difference in pressure or temperature, the higher the air velocity.
How does an air sensor work?
A hot wire air flow sensor is a more common type of air flow sensor typically used in engines that works by measuring the change in resistance of a hot wire. A thin wire is heated at a constant temperature and placed in the path of air flow which cools it down in a manner that is proportional to the rate of air flow.
What is the difference between air flow and air velocity?
Flow is a measure of air output in terms of volume per unit of time. The common units are litres per minute, cubic feet per minute (CFM), etc. Velocity refers to how fast the air is moving in distance per unit of time. The common units are feet per second, metres per second, etc.
