WebJun 10, 2024 · How it works is that it sends a small current or voltage to its sensor and then measures it across the sensor. In order to minimize the errors in this thermometer, a 4-wire connection is often used. Two wires in this system measure the voltage or current across the sensor and two wires are responsible for carrying the excitation.

What is a Thermometer and How Does It Work - TheWeatherMakers

WebA bimetal thermometer always consists of two different metal strips that have a different thermal expansion coefficient. The two strips are joined together inseparably and thus form the bimetal strip. When the temperature changes, the different metals expand to different degrees, which leads to a mechanical deformation of the bimetal strip. WebHow Does the Thermometer Work?
