The search for efficient methods for measuring magnetic field and pressure has been a constant challenge in various sectors. The lack of accurate and reliable devices has limited significant advances in areas that depend on these measurements. The invention presented in this patent solves this problem by introducing a Magnetic Field and Pressure Transducer, based on the phase variation characteristics of the GMI (Giant Magnetoimpedance) effect.
The invention enables precise magnetic field and pressure measurements. Based on the phase variation characteristics of the GMI effect, this device offers an effective method for measuring these crucial parameters.
The transducer uses sensor elements made from amorphous metal alloys on which the GMI effect is possible. With an electronic conditioning and readout circuit, the device is able to measure the phase variation of the sensor elements in response to changes in the external magnetic field.
