What are the applications of inductive sensors?
It can be directly used for displacement measurement, and can also measure any mechanical quantity related to displacement, such as force, torque, pressure, pressure difference, vibration, acceleration, strain, liquid level, etc.

Inductors and Inductors Introduction
Self-induction phenomenon: The phenomenon of electromagnetic induction caused by the current change of the coil itself. The electromotive force generated in the self-inductance phenomenon is called self-inductance electromotive force; the current generated is called self-inductance current.

Identification and Detection Methods of Common Inductance Types
There are many types of inductors with different shapes. The more common ones are: single-layer flat-wound air-core inductance coil, inter-wound air-core inductance coil, empty-core coil, multi-layer air-core inductance coil, honeycomb inductance coil, magnetic core inductance coil, magnetic tank inductance coil, high-frequency choke coil, low-frequency choke coil, fixed inductor, etc.

What welding methods are used for plug-in inductor and chip inductor respectively
Wave soldering is the formation of molten solder solder wave to solder components; reflow soldering is the formation of high temperature hot air reflow melting solder to solder components.

The role of inductance in the circuit
The common function of the inductor in the circuit is to form the LC filter circuit together with the capacitor. As we all know, the capacitor has the ability to "block DC, pass AC", while the inductor has the function of "pass DC, block AC.

Main characteristic parameters of inductance
The inductance L represents the inherent characteristics of the coil itself, regardless of the magnitude of the current. In addition to the special inductance coil (color code inductance), the inductance is generally not specifically marked on the coil, but with a specific name.

If the coil is wound, its plane is not parallel to the plane of rotation, but intersects at a certain angle, this coil is called a honeycomb coil. And its rotation, the number of times the wire bends back and forth, often called the fold number. The advantages of the honeycomb winding method are small size, small distributed capacitance and large inductance. Beehive coils are wound by using a beehive winding machine. The more folding points, the smaller the distributed capacitance.

The connection and difference between inductance and magnetic beads
Magnetic beads are used to absorb ultra-high frequency signals, such as some RF circuits, PLL, oscillation circuits, including ultra-high frequency memory circuits (DDR SDRAM,RAMBUS, etc.) all need to add magnetic beads to the power input part, while inductance is an energy storage element, used in LC oscillation circuits, medium and low frequency filter circuits, etc. Its application frequency range rarely exceeds 50MHZ.

Saturation current of inductor
Because of the orderly arrangement of magnetic domains inside the core, the magnetic field generated by the current is greatly enhanced. The greater the current, the more orderly arranged magnetic domains, the greater the magnetic field generated, and the greater the magnetic flux passing through the coil, which is basically proportional to the current.

An inductor is a component that converts electrical energy into magnetic energy and stores it. The structure of an inductor is similar to a transformer, but with only one winding. An inductor has a certain inductance, which only hinders the change of current.
