摘要
A magnetostrictive strain sensor includes a Hall effect sensor for measuring the change in magnetic flux a magnetic circuit including a magnetostrictive element. A strain sensing apparatus includes one or more magnetic elements defining a magnetic circuit having a gap, and including a magnetostrictive element adapted to receive a load force. A Hall effect sensor is disposed within the gap for sensing a change in magnetic flux in the magnetic circuit. The Hall effect sensor may include a programmable circuit for zeroing and calibrating the sensing apparatus, and for providing temperature compensation. The magnetostrictive element may be magnetized to form the magnetized element, and may be formed from material known as TERFENOL-D.
