Temperature is a measure of the average heat or thermal energy of particles in a substance. Because it is an average measurement, it does not depend on the number of particles in the object or the size of the object.

This is used to calculate the temperature value of the RTD temperature sensor from a known resistance.

Thermocouple temperature sensors belong to the category of electronic equipment called transducers. Basically, the transducer converts one physical quantity into another.

Each metal has a unique composition and has different resistance to the flow of current. This is called the resistance constant of the metal. For most metals

Instrumentation engineers seeking to measure temperature by installing sensors and thermowells into flowing fluid streams must perform many critical evaluations.

Platinum thermistor: It is widely used to measure the temperature in the range of - 200~850 ℃. In a few cases, the temperature can be measured to 1K at low temperature and 1000 ℃ at high temperature.

This article is mainly about the relevant introduction of PT100, and focuses on the calculation formula of PT100 resistance value into temperature value.

Resistance temperature sensors (RTD) and thermocouples are the two most common types of temperature sensors in industrial processes. Sometimes it is difficult to evaluate all the facts and choose the facts that better fit your application needs.

Thermocouple (TC) and resistance temperature detector (RTD) are the most widely used temperature sensors in automation and process control. They are embedded in motors, valves, turbines
