Anti corrosion thermocouple is a sensor specifically designed for temperature measurement in corrosive environments. It uses special anti-corrosion materials to make protective sleeves and junction boxes for thermocouples, in order to prevent chemical corrosion from damaging the thermocouples and ensure measurement accuracy and stability.
Anti corrosion thermocouple is a sensor specifically designed for temperature measurement in corrosive environments. It uses special anti-corrosion materials to make protective sleeves and junction boxes for thermocouples, in order to prevent chemical corrosion from damaging the thermocouples and ensure measurement accuracy and stability. The working principle is based on the thermoelectric effect. When two conductors with different compositions (thermocouple wire or thermoelectric electrode) are joined in a circuit and form two junction points at different temperatures, an electromotive force is generated in the circuit, which is called thermoelectric potential. By measuring the magnitude of the thermoelectric potential, the temperature of the measured medium can be calculated.
Anti corrosion thermocouples are usually composed of thermosensitive elements, protective sleeves, junction boxes, and other parts. Among them, the thermistor uses precious metals (such as platinum and rhodium) as electrode materials to improve its environmental applicability and temperature measurement accuracy; The protective casing is made of different anti-corrosion materials to prevent chemical corrosion; The junction box is also made of anti-corrosion materials to ensure the reliability and stability of the connection.
It has excellent anti-corrosion performance and temperature measurement accuracy, and is therefore widely used in various high-temperature measurement scenarios with corrosive environments, such as chemical, metallurgical, aerospace, petroleum, power and other fields. Especially in the production process of these fields, precise temperature measurement and control are required to ensure product quality and production safety.
Safe operation:
Before installing anti-corrosion thermocouples, it is necessary to determine their usage conditions and environment, and select the appropriate model.
During the installation process, the installation position should be cleaned to ensure that there are no foreign objects interfering, and the protective sleeve should be securely fixed.
When wiring, pay attention to polarity and ensure that the wiring is firm and reliable to avoid looseness or short circuits.
During use, mechanical collisions and bending deformations should be avoided, as well as avoiding water, oil, or corrosive liquids from entering the thermocouple head.
At the same time, it should be ensured that the temperature used does not exceed the range of the thermocouple or the range it cannot withstand.
Maintenance:
Regularly perform calibration to ensure the accuracy and sensitivity of thermocouples.
Regularly replace the protective sleeve and thermocouple head according to usage to maintain their good working condition.
During the maintenance process, appropriate welding methods should be used for repair and the welding quality should be ensured.
