A Thermocouple and Temperature Probe are innovative devices that fall under the bracket of Sensors and Transducers. Thermocouples are a type of temperature sensor, providing temperature measurements by generating an electrical signal from the temperature-induced voltage difference between two different metals. On the other hand, a Temperature Probe is a type of sensor that measures changes in temperature. It's an assembly of a thermocouple, RTD, or thermistor sensor, and a connecting device typically made of metal. These devices' primary function is to detect and measure temperature fluctuations in a variety of environments, ranging from manufacturing processes to scientific research.
The specific applications of these items are broad and diverse. Thermocouples are commonly used in industrial processes where high temperatures are present such as in gas turbine exhaust, diesel engines, and other industrial processes. Temperature Probes are often found in HVAC systems to monitor room temperatures or in digital thermometers for medical use. They are characterized by their durability, accuracy, and ability to measure extreme temperature ranges. Renowned manufacturers of these products include Honeywell, Siemens, Omron, and Emerson.
