Applications of LVDTs in industry

Tuesday, October 13, 2020

Metrology tools are a vital part of the product manufacturing process. Your choice of linear variable differential transformer (LVDT) sensor has a direct impact on product quality, brand reputation and company performance.

There is a wide range of LVDT sensors (also referred to as displacement sensors and displacement transducers) available to product manufacturers. Different sensors are suited to different applications and conditions, and selecting the right technology is critical.

Quality assurance is vital to market success and you need to choose metrology tools that provide high-accuracy measurements and precision measurement data in a way that is best suited to your product. One of the main factors that guides this decision is industry sector.

How LVDT sensors are used in the electronics industry

LVDT sensors are used by manufacturers across the industry spectrum, from aerospace, automotive and construction to electronics, energy and environmental, and are critical to the development of products of all sizes.

For example, in the electronics industry, where electrical components are becoming more and more intricate, there is a growing need to ensure precision measurements that meet increasingly rigorous and complex quality-control processes and standards.

Feather-touch probes (component case gauging), ultra-feather-touch probes (LCD and glass screen gauging) are commonly used sensors in this sector.


LVDT sensor applications in the energy and aerospace industries

In the energy sector, where the need to adhere to stringent safety regulations makes highly accurate sensor technology vital, force sensors, displacement transducers and temperature measurement sensors are commonly used metrology tools.

For example, for power station operators, it is essential that they can accurately monitor the impact of hydraulic cylinders on the structural integrity of reactor buildings. Digital probes are instrumental in the provision of this precision measurement data.

In the aerospace industry, the constant evolution of jet engine manufacturing requires the use of a variety of contact and non-contact precision aerospace sensors. Digital spring push probes and digital pneumatic probes are both widely used in the sector.
For example, displacement sensors have a key role in the manufacture of engine turbine blades. As a result of the production process, the dimensions of the turbine blade often change very slightly and LVDT sensors help ensure that they conform to strict specifications.


The types of LVDT sensor and the role of your metrology partner

Choosing the correct LVDT sensor isn’t straightforward and one of the major benefits of picking the right metrology technology supplier is that they will help ensure that you have the right precision measurement tools for your product.

Types of LVDT sensor include:

·       Digital gauge probes
·       Pneumatic displacement sensors
·       Vacuum displacement probes
·       Feather-touch sensors
·       Ultra-feather-touch sensors
·       Narrow-body digital sensors
·       Short and ultra-short digital gauge probes
·       Mini, lever and block gauges
·       Parallel, single-leaf and mini flexures

Your metrology partner should have the expertise and experience to assess your needs and advise you on your precision sensor requirements. This know-how will ensure that your products are manufactured to the highest standard and provide the performance that translates to market success.
