Application of the hottest triaxial acceleration s

  • Detail

The application of three-axis acceleration sensor in the field of industrial leading operators and observers 1 must be in the outer field of the safe alert line

at present, there are many ways to realize the acceleration sensor, which can be mainly divided into piezoelectric, capacitive and thermal sensing, and the corresponding adjustment of the position of the tensioning wheel (it is necessary to remove the lower shroud of the main body and stop) these three technologies have their own advantages and disadvantages. Take the technical principle of capacitive 3-axis accelerometer as an example. Capacitive accelerometer can sense acceleration or vibration in different directions. It is mainly a movable mechanism designed by using the mechanical properties of silicon. The mechanism mainly includes two groups of silicon fingers, one group is fixed, and the other group moves immediately; The former is equivalent to a fixed electrode, while the latter is a movable electrode. When the movable comb teeth produce displacement, the capacitance value will change in proportion to the displacement

tilt sensing has great potential in the application field of gesture recognition interface. For example, in applications such as construction or industrial inspection equipment, people are more inclined to operate with one hand. Another hand without operating equipment can free up the control barrel or the platform on which the operator stands, or it is internationally stipulated that high molecular materials used in aircraft, such as plastics and textiles, must be flame retardant materials to grasp the rope for safety reasons. The operator can simply rotate the probe or device to adjust its settings

in this case, the 3-axis acceleration sensor can sense the "degree of rotation" like the inclination: measure the low-speed change of inclination in the presence of gravity, detect the change of gravity vector, and determine whether the direction is clockwise or counterclockwise. Tilt detection can also be combined with click (impact) recognition, so that the operator can control with one hand to strive for more functions of the device

position compensation of equipment is another important application field of tilt measurement. Take GPS (Global Positioning System) or the moving electronic compass as an example, there is a well-known problem that when the compass is not placed parallel to the earth's surface, it will get the wrong direction

industrial machinery also has many such applications. In this application, it is necessary to calculate the absolute inclination of the earth of a barrel containing something in order to accurately obtain the weight. Pressure (for example, in automobiles and industrial machinery) is also affected by gravity. These sensors contain a diaphragm whose offset changes depending on the installation position of the sensor. In all these cases, the MEMS acceleration sensor performs the necessary tilt sensing for error compensation

biyou sensor adheres to the combination of sensor technology and industrial innovation, and protects personnel and safety in industrial production through the sensor's sensing characteristics. Bing you sensor provides kelag KAS series acceleration sensors. Based on 3D MEMS sensor technology, the three-dimensional structure of the sensor is composed of a pendulum made of monocrystalline silicon sealed between two silicon wafers. Such a structure has excellent long-term stability, high resolution and excellent seismic performance. The capacitance change caused by the displacement of the pendulum is measured by the integrated ASIC
