Abstract
Content
A new oil pressure sensor has been developed utilizing iron base amorphous magnetic alloys. The sensor was composed of a cylindrical body with oil inlet, the amorphous magnetic alloy strip glued around the body and coils arranged to the alloy.
The output behavior of the sensor was explained successfully by applying a rotation magnetization model. The characteristics of the developed sensor were as follows.
  • Measurable pressure range; 0 to 20MPa.
  • Operating temperature range; -30 to 100°C
  • Inaccuracy; less than 2 %F.S. (F.S. means full scale)
The durability tests like cyclic heating or pressure application demonstrated that the developed sensor is durable enough for automobile use.
