Electronic ruler use method Electronic ruler how to choose

Electronic ruler, also known as linear displacement sensor, can accurately measure the size of mechanical displacement. It is widely used in modern industry, such as woodworking machinery, spraying, machine tools and so on. And it is easy to realize digitization, high precision (currently the highest resolution can reach nano level), strong anti-interference ability, no human reading error, easy installation, reliable use and so on. Next Xiaobian introduced the use of electronic ruler and how to choose the electronic ruler.

Electronic ruler use method

First, install the battery

1, according to the direction of the battery room arrow to put;

2, the lid is pushed open, the battery room has positive and negative (+ and -) poles,

3, open the lid

4. When the battery is showing low power or the range finder cannot be operated, replace the battery.

Second, the stability of the rangefinder

This instrument is sensitive to temperature and humidity. Wait 15-30 minutes before use until the range finder stabilizes to room temperature.

Third, the use of the rangefinder switch

To turn on the instrument, press “Switch/Confirm” to display the screen easily even in dim light. When the voltage is stable, you can see the ambient temperature at that time. 30 seconds automatically closes if not used.

Fourth, the specific measurement

1. Open the key to enter the main menu and display the gauge data and operation data.

2, need to store data, please press the right button.

3, need to return to the main menu, press the confirmation key for 5 seconds to display the main menu.

How to choose electronic ruler

1, the required accuracy, linearity

2, the range of expected range

3, repeatability / resolution

4、Required torque (low)

5, environment, vibration, dust temperature, humidity

6, electrical trip

7, required speed and expected price and life

Electronic ruler fault judgment

1. Turn off the power and measure the resistance between I101 and I103, and the resistance between I102 and I103. Generally, the resistance between I101 and I103 is the sum of the resistance between I102 and I103 and the resistance between I101 and I102.

2. Move the active end of the electronic ruler. Measure the resistance between I101 and I102 or I102 and I103 should be evenly changed.

3. Observe that the resistance at this time will not change. In theory, the resistance between I101 and I103 does not change, and the resistance between I102 and I103 increases with the increase in the position of the active end, and decreases and decreases.

4. If it is found that the I102 and I103 resistance will not change, the electronic ruler will be damaged and the internal slick failure will occur.

If the resistance between I102 and I103 decreases as the active end position increases and decreases, and the computer value and the actual position change inversely, the line between I102 and I103 is reversed.

If the resistance change between I101 and I103 is found, the resistances of I102 and I103 do not change, and the resistance between I101 and I103 is greater than I102 and I103, the power supply line of the electronic ruler is connected incorrectly, and I101 and I102 need to be interchanged.

If the resistance of I101 and I103 is found to be infinite, it means that the internal resistance wire of the electronic ruler is broken.

If the resistances of I101 and I103 are found to be zero, then the internal resistance wire of the electronic ruler is short-circuited. At this time, the electronic ruler should be removed; otherwise, the A/D module of the controller will be damaged.

Editor's summary: The use of the electronic ruler and how to select the electronic ruler are introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
