Product Description

PT100 Thermocouple Product Introduction


Product Overview


PT100 thermocouple is a temperature sensor based on the principle of thermal resistance, widely used for measuring the surface and internal temperature of metal equipment, as well as for measuring the temperature of bearing shells and other specific occasions. The "PT" in its name represents platinum resistance, and "100" indicates that the resistance value of the sensor at 0 ℃ is 100 ohms.


Product Features


High precision and stability: The PT100 thermocouple has high precision and long-term stability, and its measurement error is usually very small, ensuring accuracy in various industrial and scientific applications.


Wide measurement range: The measurement range of PT100 thermocouple is usually from -200 ℃ to 850 ℃, suitable for temperature measurement in various industrial and scientific research fields.


Quick response: Encapsulated in a stainless steel shell, it has a fast thermal response time and can quickly reflect temperature changes.


Easy to install and maintain: using threaded installation for ease of use. Meanwhile, its structural design makes replacement and maintenance simple and quick.


working principle


The working principle of PT100 thermocouple is based on the characteristic of the resistance value of platinum resistor changing with temperature. When the temperature rises, the resistance value of the platinum resistor will increase; On the contrary, when the temperature decreases, the resistance value will decrease. By measuring the resistance value of a platinum resistor, the temperature of the object being measured can be calculated.



Product Structure and Application


PT100 thermocouples are usually composed of main parts such as hot electrodes, insulation sleeves, protective tubes, and junction boxes. It is usually paired with display devices, control devices, inspection devices, collectors, paperless recorders, etc. for precise temperature measurement and control. It has a wide range of applications in measuring the surface and internal temperature of metal equipment, as well as in measuring the temperature of bearings and bushings.




Product advantages


Compared with thermocouples, PT100 thermocouples perform well in the following aspects:




High precision and stability: The accuracy and repeatability of PT100 thermocouples are usually better than thermocouples, and the error can be controlled within ± 0.1 ℃, making it suitable for applications with strict temperature requirements.


Wide measurement range: Although the measurement range of PT100 is relatively limited, it performs well in the range of -200 ℃ to 850 ℃ and is suitable for temperature measurement in various industrial and scientific research fields.


Good linear response: PT100 thermocouple has good linear response and low hysteresis, which enables the output resistance change to accurately reflect temperature changes in different temperature ranges.


Precautions for use


Regular calibration: In order to ensure measurement accuracy, PT100 thermocouples need to be calibrated regularly.


Correct installation: When installing PT100 thermocouples, appropriate measuring point positions should be selected and sufficient heat exchange should be ensured between the measuring end and the measured medium.


Environmental considerations: When selecting and installing PT100 thermocouples, factors such as the temperature range of the measured medium, material stability, and response time need to be considered.


epilogue


PT100 thermocouple, as a high-precision and high stability temperature sensor, plays an important role in various industrial and scientific research fields. Its unique advantages and wide range of applications make it an indispensable part of the temperature measurement field.
