Research of Lubrication Oil Pressure Measuring Method of Auto Engine Based on Piezomagnetic Effect
In order to measure the lubrication oil pressure of auto engine accurately, the feasibility of measuring method based on the piezomagnetic effect of Fe-base amorphous alloy was researched. First, a kind of film piezomagnetic inductance pressure sensor was designed, and its structure, operation principle,output characteristic and the choice of some major parameters were discussed. Second, the static characteristic of the sensor as well as the influence of temperature, excitation circuit intensity and frequency on the output were analyzed through experiment. The experimental result shows that the designed sensor has characteristics such as higher temperature stability and reliability, simpler structure, it is feasible to measure the lubrication oil pressure of auto engine.
