Displacement Hall Effect Magnetoelectric Sensor - Agent [Weikewei]

Magnetic electric sensor is a type of sensor that converts the measured (such as vibration, displacement, speed, etc.) into electrical signals through magnetic electric action. Magnetic electric induction sensorHall sensor They are all magneto electric sensors. Magnetic electric induction sensor is a sensor that uses relative motion between a conductor and a magnetic field to generate induced electromotive force; Hall sensors are current carrying semiconductors that exhibit electromagnetic effects in a magnetic field(Hall effect)58彩票)And the sensor that outputs electromotive force. Their principles are not exactly the same, so each has its own characteristics and application scope.

Magneto electric induction sensorAlso known as electric sensors or inductive sensors. It utilizes the relative motion between a conductor and a magnetic field to output induced electromotive force at both ends of the conductor. Therefore, it is a type of electromechanical energy conversion sensor that does not require a power supply and directly absorbs mechanical energy from the measured object and converts it into an electrical signal output. It has a simple circuit, stable performance, low output impedance, and a certain frequency response range (generally 10-1000Hz), which is suitable for measuring vibration, speed, torque, and other parameters. Especially due to thissensorThe "bidirectional" nature of it allows it to be used as an "inverter" in the "feedback" (also known as force balance) sensors that have developed in recent years. But the size and weight of this sensor are relatively large.

Magneto electric induction sensorIt is based on the principle of electromagnetic induction. According to the law of electromagnetic induction, the induced electromotive force at both ends of the coil is proportional to the rate of change of the magnetic flux surrounding the coil over time. Magnetic electric induction sensors are only suitable for measuring dynamic physical quantities, so their dynamic characteristics aresensorThe main performance. For mechanical systems, solving differential equations of motion is generally used to study the dynamic characteristics of the system. This method is quite complex, and for high-order complex mechanical systems, it is difficult to solve high-order differential equations. However, there are many conveniences in applying the concept of mechanical impedance to analyze mechanical vibration systems. The concept of mechanical impedance can be applied to analyze the dynamic characteristics of mechanical systems. A simple algebraic method can be used to solve the transfer function equation that describes the dynamic characteristics of the system, without the need to solve differential equations. However, the analysis results are completely consistent.
