With the continuous development of industrial automation, temperature sensor, as an important industrial control element, is widely used in various industrial fields. PT100 temperature sensor, as a common temperature sensor, has accurate temperature measurement ability and stable performance, and has been widely concerned and applied.
The main parameters of temperature sensor PT100 mainly include the following aspects:
Scope of application:
PT100 temperature sensors are widely used in industrial automation control systems, laboratory instruments, medical equipment, food processing, chemical and other fields to measure the temperature of liquids, gases and solids.
Linearity:
The linearity of PT100 is usually ±0.1% or higher. Linearity represents the linear relationship between temperature and resistance, that is, the degree to which the resistance value changes with temperature. A higher linearity means that the relationship between temperature and resistance is more linear.
Rated resistance:
The rated resistance of PT100 is 100 ohms, that is, at 0 degrees Celsius, its resistance is 100 ohms.
Temperature range:
The PT100 temperature sensor is a platinum resistance-based temperature sensor that typically measures from -200°C to +600°C. However, some cases can also make its measurement range up to -200℃ ~ +850℃. It uses the linear characteristics of platinum resistance to achieve temperature measurement with high precision and stability.
Product accuracy:
The accuracy of PT100 is usually ±0.1 degrees Celsius or higher. This means that the sensor is able to accurately measure the temperature and provide an accurate reading within a certain range.
Allowable deviation value:
The allowable deviation value of PT100 varies according to the accuracy level. The allowable deviation for class A accuracy is ±(0.15+0.002│t│), while the allowable deviation for Class B accuracy is ±(0.30+0.005│t│). Where t is the Celsius temperature.
Response time:
The response time of PT100 is usually a few milliseconds to tens of milliseconds. This is the time it takes the sensor to change from a change in temperature to a change in the output electrical signal. The shorter response time means the sensor is able to respond more quickly to changes in temperature.
Length and diameter:
The length and diameter of the PT100 can be selected according to the specific application requirements. The common length is 1 meter, 2 meters or more, and the diameter is usually 1.5mm to 5mm.
Output signal:
The output signal of the PT100 is usually a resistance value, which can be converted into a standard voltage or current signal via a bridge or converter.
Product advantage:
PT100 temperature sensor has the advantages of high precision, good stability, strong anti-interference ability and long service life. In industrial environments, PT100 temperature sensors work stably and accurately, adapting to harsh working environments.
Product features:
The PT100 temperature sensor has the characteristics of fast response, high sensitivity, simple structure and easy installation. Its compact structure, small size, suitable for a variety of small space installation.
Temperature probe package form:
It is worth noting that there may be some differences in PT100 produced by different manufacturers, so pay attention to the specific technical parameters provided by manufacturers when selecting and using. Weilian Fenran Sensor Technology Co., Ltd. is a professional manufacturer of PT100 temperature sensor, welcome to consult and cooperate.
In summary:
As a kind of high precision and good stability temperature sensor, PT100 temperature sensor has a wide application prospect in industrial automation control system, laboratory instrument, medical equipment and other fields. Its characteristics of fast response, high precision and good stability make it an important part in the field of industrial temperature measurement. It is hoped that the introduction of this paper can help readers better understand the characteristics and application range of PT100 temperature sensor, and provide reference and guidance for its practical application.
