hi
i want to make sensor of image its for measuring distance .
in your minds which sensor is better for making that?

linear potentiometer?
How much change and what are you measuring? Is this mounted on something?

In fact, I want to measure the weight of the truck!
I saw this sensor to measure the weight of the truck load!
Now I want to build this sensor What sensor do you think I should use to build this device that measures distance?
I need your help

linear potentiometer?
How do I use a linear potentiometer?
My movement is vertical, I have to turn it into a circle! If I use less mechanical devices, it is better for less error
Do I have to use a mechanical device to convert vertical motion to rotation?
LVDT ?

LVDT ?
Lvdt is expensive!
The solution was to set up the system at a lower cost

Then why don't you use a scale?
Measuring the ride height on a truck with leaf springs will not be accurate , they have a lot of hysteresis and are non linear .
You can use Ultrasonic. I hope it is the right choice. Ultrasonic Sensor Library for Proteus - The Engineering Projects

Do you have an idea I can do this?

Load cells with high weight measurement are expensive

What is the field of view of ultrasonic sensors? I am looking for a sensor that can measure the size of about 20 to 70 cm with an accuracy of 2 cm Have a completely linear field of view
With ultrasound the material is important. A solid flat wall perpendicular to the sensor is a good reflector. A fluffy puppy or cloth curtain is not.
What kind of precision are you expecting? Commercial weight bridges can do 0.1%.
To get the weight of a truck by how much it pushes down on its springs you will need sensors at all suspension points. Besides the hysteresis in the springs and shocks, you have to make sure the tires are always inflated to the same pressure as that will also affect the height.

Accuracy of measuring 5% of the total weight of the truck
I do not want to be very careful
