Sensors play a crucial role in the development of modern technology. They serve as a bridge between the physical and digital worlds, helping us to access a wide range of environmental information. Today, we will take an in-depth look at the classification of sensors, specifically the two main categories of measurement sensors: contact and non-contact.

I: Contact measurement sensors

Contact measurement sensors acquire data by directly contacting the object to be measured. These sensors are widely used in industrial manufacturing, medical devices, and other fields. Their main advantages include high accuracy and real-time feedback. For example, in machining processes, contact sensors can monitor the wear and tear of tools in real time, thus improving productivity and product quality.

II: Non-contact measuring sensors

Unlike contact sensors, non-contact measurement sensors do not need to be in direct contact with the object to be measured, but instead measure it by means of optics, electromagnetic waves, and other means. This type of sensor is particularly common in the field of machine vision due to its greater flexibility and safety.

Measurement Sensor Usage:

1. Product observation: Non-contact measurement sensors play an important role in product observation. Through cameras and other optical sensors, the system can monitor the product quality on the production line in real time, identify defects and take timely action. This approach not only improves production efficiency, but also reduces the occurrence of human error.

2. 2D Dimensional Measurement: Non-contact sensors also excel when it comes to 2D dimensional measurement. Utilizing optical principles, these sensors can quickly and accurately measure parameters such as the length and width of an object. Compared to traditional contact measurement methods, non-contact measurement not only avoids damage to the surface of the object, but also greatly improves the measurement speed.

3. 3D Contour Inspection: D contour inspection is an important application in machine vision and an advantage of non-contact measurement sensors. Through laser scanning, stereo vision and other technologies, the system can obtain the three-dimensional contour information of the object, so as to achieve more accurate detection and analysis. This method is widely used in automotive manufacturing, electronic component inspection and other fields.
