3 Things You Need to Know About Position Sensors

Tuesday, May 11, 2021

When it comes to position sensors, there are plenty of things you should know. Given that there are various types of sensors with various potential uses, dealing with them can be confusing. This is especially true given that there is a wide array of potential applications for them, and they are used in a wide variety of industries. With that in mind, here is a shortlist of three things you need to know about position sensors.

What is a position sensor?

A position sensor is a sensor that facilitates the measurement of mechanical position. They can be used to communicate the location/ absolute position or displacement/relative position regarding traveling, three-dimensional space, or rotational angle. Therefore, they can be used in a wide array of industries such as Power Generation, Aerospace, Space, and more. For instance, in Aerospace, these position sensors also offer solutions for Thrust Reverser, Stator Vanes, Fuel Controls, and Engine Control Systems. Then, in Power Generation, they are used by the major OEMs, with typical applications being Stop Ratios, Inlet Guide Vanes, Valve Positions, and more. 

What are the different types of position sensors?

There are several position sensor types to choose from. No matter what types of sensor you may need, there is likely one that will work perfectly for your business needs. They are:

  • LVDT: Also known as Linear Variable Differential Transformers, LVDT position sensors provide users with a highly reliable solution for precise linear displacement. These sensors can be used wherever displacement transducers are used or anywhere physical position or displacement has to be converted into an electrical signal for communication purposes.
  • RVDT: On the other hand, Rotary Variable Differential Transducers are sensors that offer extremely reliable measurement solutions in terms of precision rotational position displacement. These sensors have non contacting features that ensure they are highly reliable and repeatable for angular displacement measurements.
  • HYDRASTAR®: HYDRASTAR® also offers an array of position sensors. These sensors are non-contacting conductive linear position transducers and are specifically designed for installation into hydraulic and pneumatic cylinders, as well as brand-specific actuators.
  • FASTSTAR®: FASTSTAR® also offers a line of transducers with non-contacting technology. These sensors are known for having a swift response as well as favorable stroke to body length ratios. This makes these sensors ideal for those working in fields of all kinds.

How does a position sensor work?

In terms of how position sensors work, there are some things to take note of. First of all, these sensors are versatile and have an array of uses. As mentioned above they are used in a ton of industries such as Aerospace, Power Generation, and Space, and have multiple applications for each industry. However, even if the position sensor has the same name such as an automotive position sensor or rotary position sensor type, they may work slightly differently based on the industry use. Nevertheless, position sensors essentially provide feedback in terms of the position of things. This allows them to help with things such as speed, distance, motion control, direction, and more.

Key Takeaways:

  • Position sensors have an array of uses and functions and are commonly used in the Aerospace and Power Generation industries.
  • The different types of position sensors are HYDRASTAR®, FASTSTAR®, RVDT, and LVDT.
  • Position sensors work differently depending on which industry and how they are being used.
