MODE OF COMPENSATION OF ADDITIVE TEMPERATURE ERROR OF THE SENSOR WITH A VIBRATING ELEMENT Russian patent published in 2008 - IPC G01K7/25 

FIELD: the invention refers to the field of instrument making and may be used in measuring technique at measuring power, pressure, acceleration etc.

SUBSTANCE: the initial frequencies of the generator are measured. The value of a thermal dependent resistance R_β with a temperature coefficient of resistance α_β located nearby to the vibrating element depends from the temperature of the measuring converter. The scheme of upkeep of vibrations is preliminary tuned at maximum working temperature. The initial level of the frequency of the generator of harmonic vibrations at minimal and maximal working temperatures is fixed. Besides the value of the resistance R₁₊ in the circuit of the inverting adder at maximal working temperature corresponding to the initial frequency of the generator is fixed.

EFFECT: increases accuracy of compensation of additive temperature error of the sensor with a vibrating element in the conditions of stationary temperature regimes.
