With the increasing dependence on energy, the need for modern energy monitoring sensors is also on the rise. Among all types of sensors, the thermocouple can be used to measure the temperature of a device and its surroundings. The thermocouple is a passive, two-terminal device.  

 What are the advantages? 

  1. Self-powered thermocouples are thermometers that do not require an external power source to operate. They are usually installed as a junction box connecting to a temperature sensor and a power source. When the temperature rises, the output emf increases. Thus, the output voltage can be used as a temperature reading. The main advantage of self-powered thermocouples is that they do not need any external power supply. Self-powered thermocouples can be powered by either electric current or heat energy generated by a resistor or an infrared sensor, depending on how it is wired. Therefore, they can be used in a wide range of applications, including laboratory instruments and industrial controls. 
  2. These sensors are simple and robust. They have a wide range of applications, including livestock monitoring, control systems, medical devices, and even home security systems. The key to their success is their design. These sensors are designed with high-strength metals. Because of this, they are able to endure a wide range of conditions. Because of their durability and resistance to corrosion, these sensors are perfect for use in harsh environments, like livestock monitoring or industrial control systems. In addition to their rugged design, these sensors are also affordable. This makes them a great choice for both consumer and industrial applications alike. 
  3. Thermocouples are also known to be easy to install. They can be easily connected to the existing wiring, with minimal installation required. This makes them best for use for small-scale applications. And they are very reliable as well. 
  4. Thermocouples are most commonly used to measure temperature. They’re available in a wide range of sizes and types to meet a number of different applications, including industrial settings, measuring equipment, food processing, and testing purposes. Thermocouples can be used with a number of different types of sensors to produce results. These sensors include thermistors and thermocouple elements. Each type of sensor produces a different output depending on its characteristics. When combined with a thermocouple, these sensors can be used to create an accurate temperature reading. They can measure temperatures up to 2600 degrees Centigrade. Thermocouples are essential for many applications such as power generation, automotive, and industrial applications. 
  5. They’re relatively inexpensive and easy to use, both of which make them a good choice for situations where budget or ease of use are concerns. 
  6. In addition, they typically have higher resistance compared to other types of sensors, which means that they’ll produce less noise when used in environments with high levels of vibration or movement. 
  7. And because they’re capable of measuring the temperature at a fairly low level of resolution, they can also be used in places where high accuracy is vital, such as medical facilities and food production facilities.  
  8. In addition, thermo-couples are typically more resistant to damage than other types of sensors, so they’re often preferred for situations where reliability is important. 

How does it work? 

The working principle of a thermocouple involves the Seebeck effect or thermoelectric effect. This requires two different metal wires, one of which is capable of generating an electrical current on its own by the movement of charge within it. The two metals are connected in an electrically conductive arrangement, like an electrical circuit. At room temperature, the two dissimilar metal wires are in contact, but at low temperatures, they are in thermal contact, which means that they become electrically conductive. As temperature decreases, the metal wires move away from each other, creating a potential difference between them. When the metal wires are in contact again, this potential difference is converted into electricity. 

Temperature sensors are commonplace in industrial settings as well as in cooking, laboratory and home theatres. Whether you need to keep an eye on the temperature of your fridge, a beverage machine or the temperature of your thermostat, Tempsens has the right solution for you. Whether you need a thermocouple for food safety monitoring in your kitchen or industrial applications, they have a solution that will meet your needs. You can choose from different materials and adornments to suit your specific requirements.
