METHOD OF COMPENSATING MULTIPLICATIVE TEMPERATURE ERROR OF PICKUP WITH VIBRATION MEMBER Russian patent published in 2007 - IPC G01K7/00 

FIELD: measuring technique.

SUBSTANCE: method comprises adjusting voltage-controlled generator to set it in resonance with the vibration member at the maximum operation temperature, recording the resistance in the feedback circuit of normalizing output amplifier that is included in the phase converter, determining the initial value of the output signal and value of the output signal when the nominal measured parameter from the phase converter acts at the limit values of the operation temperature range, calculating deviation of the output signal from the phase converter from the measured parameter for each temperature values, determining sign of the temperature resistance coefficient of the thermosensitive resistance, calculating the nominal value of the thermosensitive resistance, and connecting the thermosensitive resistance to the feedback circuit of the normalizing output amplifier.

EFFECT: enhanced precision.
