Ban=7 \t _blank sensor and instrument forum Magnetostriction means that some metals, such as iron or nickel, have the ability to flex under a magnetic field. Magnetostrictive effect is very subtle, the general nickel iron alloy is 30ppm, but now the scientific community has designed an updated material, the magnetostrictive effect increased to more than 1500ppm. The principle of magnetostriction is not complicated, it uses two different magnetic field generated by intersecting a strain pulse signal (Start? Pluse), and then calculate the measured signal with the time period required to calculate the exact location. The two magnetic fields, one from the moving magnet, the other to the free sensor of the electronic component produced by the current pulse. The pulse, called interrogation signal, travels along the sensors Waveguide waveguide, made of magnetostrictive material, at the speed of sound. When the two magnetic fields intersect, the waveguide generates magnetostriction and generates a strain pulse. The pulse, known as the return signal, was quickly detected by the sense circuit. From the moment of the interrogation signal to the return signal, the time period required by the control to be multiplied by the fixed sound speed, we can accurately calculate the position change of the magnet. The process is continuous, so whenever the moving magnet is driven, the new position will soon be sensed. The output signal is the absolute value of a real, rather than the proportion or need to signal amplification processing, so there is no signal drift or variable values, not to like the other type displacement sensor is calibrated periodically as needed.
