Abstract

In order to measure the wide range rotation speed in engineering

a kind of rotation speed measurement method based on magnetorsistive sensor is proposed and the circuit is designed.The uncertainty of measurement caused by dissymmetry magnetic field and wide range of rotation speed in the application is studied in detail.As a result

the conditioning circuit parameters are got

which makes the measurement work well at a high rotation speed of 120 000 r/min.It is applied successfully to the micro turbine engine control system.
