The Dynamic Characteristics of AD590
The dynamic characteristics of temperature sensor are very important in industrial temperature measure. In this paper, the dynamic characteristics of temperature sensor of AD590 has been researched on the same step volume and different initial temperature, and the different step volume and the same initial temperature, and in the state of the protected pipes and unprotected pipes by combining the theoretical model and many experimental data. Based on the theory of dynamic characteristics of sensor, a large number of experiment data was analyzed and compared, the time constant τ was obtained, also we discussed the relationship between the time constant and the amount of the step, and predicted the mathematical model and analyzed the main factors that affecting the dynamic characteristics of temperature sensor.
