Digital thermometers are temperature-sensing instruments that are easily portable, have permanent probes, and a convenient digital display. The way a digital thermometer works depends upon its type of sensor. Sensor types include resistance temperature detector (RTD), thermocouple and thermistor.
Besides, why is it important to measure the temperature?
Temperature is one of the most important measurement parameters that is used for monitoring and control in various industries. It can be measured with the help of a diverse temperature measurement devices. This post will discuss how temperature measurement is important in different industries.
What is the purpose of the thermometer?
The operating principle of a thermometer is quite simple. A known measure of liquid (mercury, alcohol, or a hydrocarbon-based fluid) is vacuum-sealed in a glass tube. The liquid expands or contracts when air is heated or cooled.
What is a thermometer and how does it work?
It is called a thermometer. "Thermo" means heat, and "meter" means a measuring device. Some of the things we measure are the temperature of the air, the temperature of our bodies, and the temperature of food when we cook. When it is hot, the liquid inside the thermometer will expand and rise in the tube.
