Dynamic calibration methods for both transducers of ultra high and ultra low temperature

摘要

The dynamic calibration methods for both transducers of ultra high and ultra low temperature are presented in this paper. The dynamic calibration methods for general temperature transducers are already detailly discussed in Ref. The dynamic calibrations of following transducers are detailly discussed in the Ref.: force, acceleration, angular speed (gyroscop), pressure , temperature, angle of attack, resonant vibration pressure transducer, many kinds of servo transducer, etc. The dynamic excitation signal generators of different kinds of transducers are quite" different in the dynamic calibration systems, but the other parts of the dynamic calibration systems are very similar , e . g . The data acquisition and recording equipment of the dynamic responsed signal of calibrated transducers. So, the dynamic excitation signal generators of both transducers of ultra high and ultra low temperatures and the block diagrams of dynamic calibration systems are presented in this paper. Finally, some discussions of the dynamic excitation signal generators of different kinds of the temperature transdures are given.
