Basic Things You Need to Learn About Sensors

position sensorThanks to modern technology, sensors have become more efficient. The main feature of these tools is to generate data from the physical parameter and transfer signals as the input to the device. Today, there are many different types of position sensors. Each has their own features and specifications. Read on to know more about it.

What is a position sensor?

As mentioned above, the use of this technology has evolved all over the years. There are now humidity sensors, pressure sensors, level sensors, and so on. But the most popular type is the position sensor. This measures the distance travelled by the body starting from its reference position. also mentions that absolute position sensors can easily detect different motions of the body — whether rectilinear or curvilinear.

Common types of position sensors

There are different processes to detect displacements of a body. Depending on the specifications for position sensors, you can classify them as follows:

  1. Eddy Current based position sensor
  2. Capacitive position sensor
  3. Optical position sensor
  4. Fiber-Optic
  5. Magnetostrictive linear position
  6. Half Effect based magnetic
  7. Linear voltage differential transformers

Potentiometric position sensors

Unlike other sensor types, potentiometric is easier and more convenient to use or install. This type of position sensors utilizes resistive effect to gather signals from interceptor. In this process, they usually attach wiper to the body or part of the body where you need to measure. The wiper should be connected to the track. The good thing about these sensors it can read and transfer signals even when you move quickly in any position. The unit will only change when the position is linear.

Common types of potentiometric sensors

  1. Cermet
  2. Wire wound
  3. Plastic film

It can be quite complicated to understand how the system works. So, before you install the right piece for your device, make sure to do your research and consult a professional.
