METHOD OF TEMPERATURE ERROR COMPENSATION FOR SENSOR WITH VIBRATION ELEMENT

摘要

FIELD: physics. ^ SUBSTANCE: invention claims a method of temperature error compensation for a sensor with vibration element, involving adding of a temperature-dependent resistance sensor with positive temperature resistance coefficient (TRC) of alphaalpha. The temperature resistance already attuned has negative TRC alphabeta. One of the temperature-dependent resistances Ralpha is aimed at compensation of multiplicative temperature error, while the other temperature-dependent resistance Rbeta is aimed at compensation of additive temperature error. Sustaining scheme for vibration element is adjusted at the maximum work temperature in advance. Required values of temperature-dependent resistances Ralpha and Rbeta and temperature-independent resistances R2L and R"1". Values of temperature-dependent and temperature-independent resistances are calculated by an equation system. ^ EFFECT: improved precision of temperature error minimisation for a sensor with vibration element in stationary temperature modes. ^ 5 dwg
