The working principle of linear displacement sensor is the same as that of sliding rheostat. It is used as a voltage divider, and it presents the actual position of the measured position with relative output voltage.

For the inspection of automobile parts, the size inspection should be the most important, and LVDT displacement sensor (differential transformer displacement sensor) must be used to detect and control the size. As a displacement sensor with strong environmental adaptability, high precision and durability, LVDT displacement sensor is the first choice in parts inspection system. So what is the specific application of LVDT displacement sensor in automobile parts inspection?

The advantages of LVDT mainly include: non-contact principle, good wear resistance, high resolution, good repeatability, no sliding contact and long service life; Fast response speed; High linearity; Good repeatability; Wide range coverage; Low fault/low power consumption/diversity of input and output; Good dynamic characteristics, can be used for high-speed online detection, automatic measurement and automatic control; Can be used in harsh environments such as humidity and dust; Can work under special conditions, such as high pressure resistance, high temperature resistance, radiation resistance, full-tight soil seal working underwater; It can withstand impact up to 150g/11ms, vibration frequency 2KHZ acceleration 20 g; Small size, low price and high performance-price ratio.

Inductive proximity sensors are widely used in industrial automation, robotics, machinery manufacturing and other fields. For example, in the automatic production line, sensors can be used to detect the position, existence and motion state of the workpiece, so as to realize the automation and intelligence of the production process. In addition, it can also be used to detect the speed of sprocket teeth in textile, chemical fiber, machine tool, machinery, metallurgy, locomotive and automobile industries, the speed and distance of chain conveyor belt, and the control of automobile protection system.

The working principle of a linear displacement sensor is to use a variable resistance slide rail structure. When the slide moves on the slide rail, the resistance value changes. By measuring the voltage difference between the slide rail and the fixed end, combined with the total resistance of the slide rail, the displacement can be calculated.

Automation equipment is not only a tool, but also a core engine to promote the transition of human industrial civilization from "age of steam" to "intelligent era". Its function is not only reflected in the improvement of production efficiency, but also profoundly affects industrial structure, economic model and even social development. The development trend of automation equipment includes improving accuracy, efficiency and intelligence, so the linear displacement sensor, as the core sensing element in automation mechanical equipment, plays a key role in equipment upgrading and intelligent development.:

Installing and debugging linear displacement sensor is a key step to ensure accurate measurement of equipment. The following is the detailed installation and debugging process:

Inductive proximity sensor has many remarkable advantages in industrial production, which make it widely used in automation control, safety monitoring and accurate measurement. The following is a detailed summary of the advantages of inductive proximity sensors in industrial production:

There are many points to pay attention to when using a linear displacement sensor, and now we will elaborate on the following important points:
