Oxford University researchers invent a new proximity sensor
Researchers at the Department of Physics at the University of Oxford have invented a new proximity sensor for the detection of metallic, non-metallic, ceramic, glass and plastic materials. This sensor can be used as a position or speed sensor in automotive suspension, gearbox and engine control systems. Early sensors were single-function and performance was limited by the behavior of magnetic induction, magnetoresistive or Hall devices. Today's new products are relatively simple but widely used to meet the requirements of measuring the motion of a variety of metallic and non-metallic objects.
The new proximity sensor consists of an oscillating circuit, an antenna and a discrete sensing unit, all integrated into a small unit. By detecting the disturbance of the electromagnetic field generated by the antenna, it can detect the distance between the target and the sensor, and can simultaneously detect the electric field and magnetic field characteristics of the measured object. The sensor does not need to change the measurement mode regardless of whether the measured target parameter changes.
Tests have shown that the sensor can detect a variety of metals, including ferromagnetic materials, non-ferromagnetic materials, non-ferrous metals, ceramics and plastics. Researchers have used sensors as timing ignition sensors on internal combustion engines, and measurements have shown that the sensors are highly sensitive and have high output characteristics. Moreover, it can detect rotating magnetic fields, non-magnetic metal gears and even plastic gears. In addition, this sensor is characterized by high temperature resistance, can work for a long time at temperatures exceeding 1000 ° C and maintain a good signal to noise ratio. At the same time, its mass production cost is low and its size is small. In addition, the sensor measures the flow of uneven fluids such as blood, brine, water-oil mixtures, and more.
