Highly sensitive, the magnetic impedance (MI) sensor, is based on the MI effect discovered in 1993 by Dr. Kaneo Mohri, a professor emeritus at Nagoya University, An extremely accurate and robust heading may be calculated by using a magnetometer and combining it with the data from GNSS and IMU sensor packages. WebThe detector module powers the loop and causes a field to form around the loop. Due to their simplicity and operating mode, magnetic loops are one of the most used traffic sensors in Intelligent Transportation Systems (ITS). Magnetic fields, as exemplified by the magnetic field of the earth (earth magnetism) or magnets are familiar yet invisible phenomena. The FESP 5134-1 is intended to be used with 50 Ohms measuring equipment, e.g. The sensor thus recognizes the field of the magnet integrated into the piston through the actuator wall. After finding the location of the magnetometer in their phones, they simply should create a loop with the magnetometer in its center and measure the change in the magnetic field perpendicular to this loop.
