Inductive sensor using principle of self-inductance is adopt to measure of iron fine powder grade
and analyze the mechanism of induction of the inductive sensor.ANSYS 12.0 finite element simulation software is utilized to set a 3D cylindrical iron powder grade sensor temperature field simulation model.Internal temperature field of inductive sensor are simulated and analyzed.Corresponding change of heat distribution of sensors in different temperature is determined.Furthermore
experiments of sensor temperature storage are carried out
and the law of impacting of the ambient temperature on output of sensor is analyzed.Through temperature field simulation and reliability environment temperature test
effect of temperature on iron powder grade measurement is discussed
and corresponding methods is considered to reduce or control temperature effect
to lay necessary foundation to achieve quick testing for iron grade.
