In engine of large ship

temperature of gear and bearing and other components in high temperature environment are datas which must be monitored in engine operating

and aiming at this kind of dynamic temperature measurement

temperature sensor with short dynamic response time is generally used. To actualize exact detection on dynamic response time of temperature sensor

dynamic response testing system of thermocouple is designed to detect dynamic response characteristics of thermocouple and factors which affect on measurement precision of system is analyzed. The result of experiment indicates that dynamic response characteristics test system is stable

and measurement result is accurate and credible.
