Abstract
Ways of solving the rotary machines intelligent vibration sensors increasing the temperature stability problem using piezoelectric accelerometers are considered. A method is proposed for increasing the vibration measurement accuracy by determining the piezoelectric accelerometer conversion coefficient current value without dismantling it from the operating object and without taking the rotary machine out of the operating mode. An algorithm for implementing the method in a digital vibration monitoring system intelligent sensor is described. The experimental studies results are presented, showing that the proposed method use can significantly reduce the additional temperature error in measuring the turbine units vibration parameters and other rotary machines. # CSOC1120.
