| Abstract: | On the basis of brief derivation for the theoretical formula of vibrating string transducers, the reason of revision is stated and the revised formula is given. The calculation through an example shows that the revised formula can significantly enhance computational accuracy. Finally, the calibration results of a vibrating string pressure transducer with a measuring range of 50 MPa are given, the constants and the relative computation error of the transducer are calculated by the revised formula. |
