Problem of Pressure Pulsation Measurement in Pipe-Lines of Refrigerator Compressors

Abstract

The paper proposes a design of an inductive transducer for measurement of pressure pulsations in pipelines of refrigerator compressors and methodology on calculation of its main parameters. The proposed transducer is differential by temperature and insensitive to a steady-state pressure component. The paper gives description of a method how to increase sensitivity of the transducer owing to magneto-elastic effect.
