What is a platinum-rhodium thermocouple and what are its characteristics Platinum-rhodium thermocouple, the temperature range is 0~1800 degrees. Liquids, gases, vapors within the frame. Lead wire is required. The platinum-rhodium thermocouple is used as a temperature measurement sensor in the industry, it can directly measure the temperature of various products -250-1800 in the range of liquid, gas, vapor medium, and solid surface temperature. It is widely used in petroleum, chemical, pharmaceutical, machinery, metallurgy, ceramics and environmental protection industries. Working principle and characteristics: 1. The thermocouple is made of a pair of different metal conductor materials (one and two), and is used as the thermal effect of the temperature measurement circuit. When there is a temperature difference between the measurement and the reference terminal, it will have a thermoelectric, and the meter will display the temperature value corresponding to the thermoelectric wire. 2. Thermal resistance, including resistance platinum, copper and electronic components. Under the action of body temperature, the resistance of the wire changes, therefore, there is a certain linear relationship. 3. The structure is simple to install, easy to use and maintain. 4. High-precision measurement (such as thermocouple directly in contact with the temperature of the medium). 5. Small thermal inertia, fast dynamic response, and adaptability to the environment.
