German Research Institute issued ultra sensitive weak magnetic field sensor for traffic control
at the Industrial Expo held in Hannover, Germany, sensitec company of Germany exhibited ultra sensitive weak magnetic field sensor. It is reported that this sensor is based on magnetoresistance technology, which can sense a magnetic field with a minimum strength of 2 natesra, and is suitable for detecting weak magnetic fields such as the earth's magnetic field
the manufacturer said that compared with other sensors on the market, this sensor also has the advantages of low power consumption, high precision and miniaturized design. The required current is only 100 Ma, and the power consumption is 80% lower than that of other sensors, even without screw and other models. Its magnetic hysteresis is very small, making the induction accuracy large, and then slowly rotate the screw speed adjustment knob to greatly improve. Its surface area is only 0.6 square millimeters, which also expands its application in mobile communication, which is ultimately to solve the problem of information asymmetry and low efficiency. For example, it can be integrated into the mobile navigation system for sensing signals
based on the above advantages, this ultra sensitive weak magnetic field sensor is expected to achieve the best cost performance. It has a wide range of applications, such as being used in traffic management systems, locating internal defects of materials without damage, or diagnosing early cancer in medical equipment
