LVDT Application Videos

Learn how LVDT position sensors are used in common applications with our videos below.  In practice, these sensors can be employed in a wide range of applications and environments.  NewTek LVDTs can withstand harsh environments and operate without interruption for years or even decades.  Resistant to dust, dirt, water, debris, and extreme temperatures, these sensors are ideal for industrial areas, power generation plants, chemical processing plants, pulp & paper, and other environments where ruggedness and reliability are key.

Not only for heavy industrial environments, NewTek LVDTs are also precise enough for laboratory use.  With sub-micron resolution and 0.25% maximum non-linearity, extremely small changes in position can be measured accurately.  With no moving parts, the LVDTs mechanical life is infinite and there is no inaccuracy due to friction or stiction.  Ideal for materials testing, actuator feedback, and gauging, these LVDTs can perform reliably in both the laboratory and the factory floor.

Valve Position Video

See how the LVDT can be used to monitor the position of a gate valve.  Typically, the LVDT’s housing will be mounted in a fixed location.  The LVDT core rod should be connected to the valve’s mechanical indicator.  As the mechanical indicator moves, so does the LVDTs core within the LVDT, changing its output proportionally to the position of the core.  For more information on how an LVDT works, visit our LVDT Tutorial.

Spring loaded LVDTs are ideal for performing quality checks on parts following fabrication or on the assembly line.  Complex cast automotive components can be probed at several key points using LVDTs to ensure the dimensions are within specifications.  Rollers can be probed that control the thickness of a product, or the product itself can be probed as a quality check.

In the below video, the height of boxes is measured by the spring-loaded LVDT to be sure it is within tolerance.   Paired with the NTC-6000 to deliver an analog DC output, the LVDT is mounted to a plate that raises and lowers the LVDT into measuring position.  Once there, the position reading determines if the height of the box is in or out of tolerance.
