At Airex Heaters, we manufacture both RTD (Resistance Temperature Detector) and Thermocouple temperature sensors for a variety of industrial applications.
Thermocouple:
A thermocouple is a type of temperature sensor that uses two different metals or metal alloys joined together at one end to create a thermoelectric circuit. When the junction of the two metals is exposed to a temperature gradient, a small voltage is generated, which is proportional to the temperature difference between the junction and the other end of the thermocouple. Thermocouples are suitable for high-temperature measurements ranging from -200°C to +2300°C and are relatively inexpensive, durable, and versatile. However, they have lower accuracy compared to RTDs, especially at low temperatures.
At Airex Heaters, thermocouples are manufactured in a variety of styles, such as thermocouple probes, thermocouple probes with connectors, infrared thermocouples, transition joint thermocouple probes, bare wire thermocouples or even just thermocouple wire.
Resistance Temperature Detector
RTDs, on the other hand, are temperature sensors that use the principle of the resistance of a metal to change with temperature. They are made of a length of wire wound around a ceramic or glass core, and the wire's resistance increases with temperature. RTDs are suitable for temperature measurements ranging from -200°C to +850°C and are known for their high accuracy, repeatability, and stability. They also have a faster response time than thermocouples. However, RTDs are more expensive than thermocouples and require a constant current source for accurate measurements.
Airex Heaters specializes in manufacturing high-quality Resistance Temperature sensors for various industries that are known for their accuracy, stability, and reliability. Airex Heaters offers a wide range of temperature sensors, including standard Stainless Steel, nickel, and copper according to the client's requirements.
We at Airex are specialized in manufacturing two types of sensors (Thermocouples and RTDs) that operate on different principles and have different characteristics, which make them suitable for different applications.
Here are some examples of their uses:
Industrial Applications: Thermocouples are commonly used in industrial settings to monitor and control the temperature in manufacturing processes, power generation, and other applications that require high-temperature sensing. They are often used in furnaces, boilers, and other high-temperature equipment.
Automotive and Aerospace: Thermocouples are also used in the automotive and aerospace industries to monitor engine temperatures, exhaust gases, and other critical components.
Food Industry: Thermocouples are used in the food industry to monitor and control temperatures during cooking, cooling, and storage processes.
Medical Applications: Thermocouples are used in medical applications, such as monitoring body temperature and measuring the temperature of medical equipment.
HVAC Systems: Thermocouples are used in heating, ventilation, and air conditioning (HVAC) systems to measure air and water temperature in ducts, pipes, and other equipment.
