Abstract: Research on dynamic performance of temperature sensor is relevant to the measurement accuracy of transient process and real time monitoring of control system, which has major engineering value and factual significance in the field of national defense and aerospace. A testing system of dynamic performance of temperature sensor was designed to calibrate the 7 kinds of thermocouple temperature sensors with different structures. By the contrast analysis of the test results on time constant and response time, it will provide a reference in selection and application of thermocouple for temperature dynamic measurement.

Key words: Thermocouple, Dynamic property, Response time, Metrology and measurement technology
