In this video, I present to you a circuit where a temperature controller uses a thermocouple and rtd to turn the heaters on and off automatically • Temperature control refers to the regulation of temperature in a system or environment to maintain it at a desired level. It is used in a variety of applications, such as in HVAC systems, • refrigeration, and industrial processes. The control of temperature can be achieved through the use of thermostats, sensors, and actuators, and can be managed by manual or automated means. The goal of temperature control is to ensure comfort, maintain efficiency, and prevent damage to equipment or materials. • Thermocouple sensor. • • A thermocouple is a temperature sensor that consists of two different metal wires joined at one end, creating a junction. When the temperature at the junction changes, a small electrical voltage is produced that can be measured to determine the temperature. This voltage is directly proportional to the temperature difference between the hot junction and the reference junction. Thermocouples are commonly used in a variety of applications, including industrial processes, HVAC systems, and consumer appliances, due to their accuracy, wide temperature range, and ruggedness. • Thermocouple sensor type. • There are several types of thermocouples, including: • Type J: Iron-Constantan • Type K: Chromel-Alumel • Type T: Copper-Constantan • Type E: Chromel-Constantan • Type N: Nicrosil-Nisil • Type S: Platinum-Rhodium • Type R: Platinum-13% Rhodium • Each type of thermocouple has different characteristics and is suited for different temperature ranges, environments, and applications. For example, Type K is widely used due to its accuracy and ability to measure high temperatures, while Type J is commonly used for low-temperature measurements. When selecting a thermocouple, it's important to consider factors such as temperature range, accuracy, and durability. • RTD Sensor. • An RTD (Resistance Temperature Detector) is a type of temperature sensor that measures temperature by using the resistance of a metal element, typically platinum, nickel or copper, which changes with temperature. RTDs are highly accurate and stable, and can measure temperatures over a wide range, from below freezing to over 1000°C. They are commonly used in industrial processes, HVAC systems, and laboratory applications where precise temperature measurements are required. RTDs are connected to an electrical circuit that measures the change in resistance, which is then used to calculate the temperature. The resistance of the RTD is typically measured using a Wheatstone bridge circuit, which provides a precise measurement of the resistance change. • There are also different types of thermal resistors (RTD) sensors, including: • Pt100 • Pt1000 • Cu50 • Ni100 • Ni120 • Lastly, there are infrared temperature sensors, which measure temperature by detecting the thermal radiation emitted by an object. • • Thanks for watching video please subscribe my channel. • Watch out: **electrical wiring is very dangerous**you could be shocked or killed. If you are not trained and familiar with proper, safe electrical wiring practices don't try it. • • Background Music - • Cherish by Roa / roa_music1031 Creative Commons — Attribution 3.0 Unported — CC BY 3.0 Free Download / Stream: https://bit.ly/3iIebfw Music promoted by Audio Library  • Cherish – Roa (No...
