Laser displacement sensors are often used to measure physical quantities, such as length, distance, vibration, speed, direction, etc. They can also be used for flaw detection and air pollutant monitoring.

Nowadays, in addition to ultrasonic sensors and ordinary photoelectric sensors, a new method that can solve long-distance measurement and inspection has been added to the methods of automatic detection and control - transmission time laser distance sensor. So what are the broad uses of laser displacement sensors in the field of automation? It provides flexibility for a wide variety of applications, which Liyi says can include the following:

In order to facilitate the user to understand the operating status of the sensor in real time, there are six sets of signal lights on the panel of the spectral confocal sensor, which show the actual situation of the sensor from four aspects: power supply, USB connection, measuring head connection and measurement status. Today, spectrometer spectral confocal manufacturers will talk about the understanding of spectral confocal sensor signal lights.

What is the confocal imaging principle of spectral confocal sensor? Friends who do not know and are interested in understanding can follow the spectrometer spectral confocal manufacturers to see, in fact, the confocal imaging of the spectral confocal sensor is based on two principles, what is it?

How does the laser displacement sensor work? Many tools and products of modern technology have replaced the previously complex manual operations. For example, the displacement sensor is a high-tech product, but many customers ask how the laser displacement sensor works. Now Liyi will share with you!

The spectral confocal dark signal is generated by the back reflection (noise) of the optical surface inside the sensor. This signal must be stored in a memory unit that is not easily lost in order to be subtracted from the actual signal measured. The level of the dark signal depends on the sampling rate and LED brightness. Today, the spectrometer spectral confocal manufacturer will talk to you about how the spectral confocal sensor can obtain Dark signals:
