Principle of Operation The sensor is a magnetostrictive device consisting of a diaphragm, nickel tube, magnet, drive coil, and pickup coil. When 40kHz energy is applied to the drive coil, it causes the diaphragm to vibrate at a frequency determined by the mechanical resonant system of the sensor. Electrical energy is transferred to the pickup […]
