Abstract: With FORTRAN programmes, the characteristic curve fit and the temperature compensation of a vibrating cylinder pressure transducer are fulfilled. The numerical results show that the non-linear error of the transducer is reduced considerably from its original value 6.3% down to±0.05% and the error caused by temperature may be completely compensated at the testing points. The programmes are simple and very fast in computation. They can be applied universally to any vibrating cylinder pressure transducer: the constants to be determined may be obtained simply by changing the input data. These programmes are also suitable for other similar transducers. All the programmes, including the source programme and the subroutine, are given in considerable details.
