Werkomgevingsbereik van platina RTD-temperatuurtransmitter
Platinum RTD temperature transmitter is a commonly used temperature measuring instrument, widely used in industry, scientific research, medical and other fields. It has the advantages of high measurement accuracy, good stability and strong anti-interference ability. However, the working environment of Pt RTD temperature transmitter has a great influence on its performance and life.
The working environment temperature range of platinum RTD temperature transmitter is an important factor affecting its performance and life. Generally speaking, the operating temperature range of platinum RTD temperature transmitter is -50℃~+850℃. In this temperature range, the platinum RTD temperature transmitter can work normally, and the measurement accuracy and stability can be guaranteed.
1.1 Low temperature environment
In low temperature environment, the measurement accuracy of Pt RTD temperature transmitter may be affected. When the ambient temperature is lower than -50℃, the resistance value of the platinum RTD will change, resulting in an increase in the measurement error. In addition, the low-temperature environment may also cause the insulating material of the platinum RTD temperature transmitter to become brittle, affecting its insulating properties.
1.2 High temperature environment
In a high temperature environment, the stability and life of the Pt RTD temperature transmitter may be affected. When the ambient temperature exceeds +850°C, the resistance value of the platinum RTD will increase rapidly, resulting in increased measurement error. At the same time, the high temperature environment may also lead to deformation of the housing material of the platinum RTD temperature transmitter, affecting its sealing performance.
Humidity is another important factor that affects the performance and life of platinum RTD temperature transmitters. Generally speaking, the working humidity range of platinum RTD temperature transmitter is 10%~95% RH. within this humidity range, platinum RTD temperature transmitter can work normally, and the measurement accuracy and stability can be guaranteed.
2.1 Low humidity environment
In a low humidity environment, the insulating property of Pt RTD temperature transmitter may be affected. When the ambient humidity is lower than 10% RH, the low moisture content in the air may cause the insulating material of the platinum RTD temperature transmitter to become brittle, affecting its insulating performance.
2.2 High humidity environment
In a high humidity environment, the measurement accuracy and stability of the Pt RTD temperature transmitter may be affected. When the ambient humidity exceeds 95% RH, the moisture content in the air is high, which may lead to moisture in the case material and insulating material of the platinum RTD temperature transmitter, affecting its sealing performance and insulating performance.
Pressure is another important factor that affects the performance and life of platinum RTD temperature transmitters. Generally speaking, the working pressure range of platinum RTD temperature transmitter is 0~10MPa. In this pressure range, platinum RTD temperature transmitter can work normally, and the measurement accuracy and stability can be guaranteed.
3.1 Low pressure environment
In a low-pressure environment, the measurement accuracy and stability of Pt RTD temperature transmitters are usually not affected. However, if the pressure is too low, it may lead to deformation of the housing material of the platinum RTD temperature transmitter and affect its sealing performance.
3.2 High-pressure environment
In high-pressure environments, the stability and lifetime of the Pt RTD temperature transmitter may be affected. When the working pressure exceeds 10MPa, the housing material and sealing material of the platinum RTD temperature transmitter may be affected by the pressure, resulting in a decline in sealing performance or even leakage.
Vibration and shock is another important factor affecting the performance and life of Pt RTD temperature transmitters. Generally speaking, platinum RTD temperature transmitters can withstand a certain amount of vibration and shock, but excessive vibration and shock may result in damage to their internal structure, affecting measurement accuracy and stability.
4.1 Vibration
The stability of Pt RTD temperature transmitters may be affected in a vibrating environment. Excessive vibration may cause the internal structure of the Pt RTD Temperature Transmitter to loosen, affecting its measurement accuracy and stability.
4.2 Shock
The internal structure of the Pt RTD temperature transmitter may be damaged in a shock environment. Excessive impact may cause the shell material and internal structure of the Pt RTD temperature transmitter to rupture, affecting its sealing performance and measurement accuracy.
Electromagnetic interference is another important factor affecting the performance and life of Pt RTD temperature transmitters. Generally speaking, platinum RTD temperature transmitter has a certain anti-interference ability, but in a strong electromagnetic interference environment, its measurement accuracy and stability may be affected.
Chemical corrosion is another important factor affecting the performance and life of platinum RTD temperature transmitters. In some special environments, platinum RTD temperature transmitter may be affected by chemical corrosion, resulting in damage to its housing materials and insulation materials, affecting its sealing performance and insulation properties.
In summary, the range of operating environments of platinum RTD temperature transmitters has a great impact on their performance and life. In order to ensure the normal operation and measurement accuracy of platinum RTD temperature transmitter, it needs to be used in the appropriate temperature range, humidity range, pressure range, and try to avoid vibration, shock, electromagnetic interference and chemical corrosion and other unfavourable factors.
