FIELD: test of parameters of means measuring vibration. SUBSTANCE: resonance oscillations of accelerometer are excited during long operation of piezoelectric accelerometer without its dismantling by its connection to source of constant voltage to test conversion factor in each test cycle with subsequent disconnection and short-time closure of its leads and are recorded. Initial cycle is conducted immediately after installation of accelerometer on object of measurements. In each cycle value of parameter Q is found by swing of signal of accelerometer in each half-cycle and value of conversion factor Sn in n-th cycle is determined by mathematical formula which includes value of parameter Q and initial value of conversion factor determined by direct test. EFFECT: increased accuracy of measurement of vibration. 1 dwg
