How thermocouple thermometer works
Nettet8. sep. 2024 · A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system. NettetA thermocouple is made up of two dissimilar metals, joined together at one end, that produce a voltage (expressed in millivolts) with a change in temperature. The junction of the two metals, called the sensing junction, is connected to extension wires. Any two dissimilar metals may be used to make a thermocouple. Principle of Operation

Nettet10. jun. 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.
