Thermal imaging – Technology basics

  Infrared radiation is emitted by all objects with a higher temperature than absolute zero, so thermography or thermal imaging allows you to see an environment, location, or person with or without visible light. The amount of radiation of an object increases with temperature, so thermography also helps you to see variations in temperature. As a general rule, places or objects that appear on a thermal imaging camera with green or blue colors have low temperatures. An increase in temperature leads to color changes on the camera as well, so that most people and warm-blooded animals become easily visible on Read More

What types of anemometers are there?

  An anemometer is the most commonly used instrument which can measure the wind speed. The types of anemometers available are various, suited for specific situations, environments, and measurements. The categories of anemometers are based on velocity and pressure units. Velocity anemometers Velocity anemometers include cup anemometers, vane anemometers, hot-wire anemometers, laser Doppler anemometers, ultrasonic ones and ping-pong-ball models.   Cup anemometers The cup anemometer is a basic type that consists of four hemispherical cups attached to horizontal arms, which are connected to a vertical rod. The wind passing the cups in any horizontal direction spins the rod at a Read More

A short history of the anemometer

  An anemometer is an instrument that is used to determine the speed of wind, a very common device in pretty much all weather stations. The word is derived from “anemos”, which means wind in Greek, and it is utilized for describing any speed of the wind in meteorology. The first known description of an anemometer was offered in 1450 by Leon Battista Alberti. A short history This device has been through some changes since its development from the 15th century. Leon Battista Alberti (1404-1472) is stated to have invented the first mechanical anemometer around 1450. In the centuries to Read More

How to make an anemometer

  An anemometer is an instrument designed to measure the speed of the wind. There is a various range of anemometers created for specific types of environments, measurements, and situations. One of the basic models is the cup anemometer, and newer, more accurate devices are based on laser or ultrasonic measuring technology. A Robinson anemometer, a utilized name for the cup anemometer, uses cup-like pieces to catch the wind, making the device rotate. The number of the spins in a limited time interval allows you to calculate how quickly the wind is moving. This article represents an example of how Read More

How do anemometers measure wind speed?

  Did you notice that the weather reports often mention the wind speed? Have you ever wondered how it is measured?   The instrument used to measure wind speed is called an anemometer.
