For thickness measurement, manufacturers have a number of options: optical, capacitive, inductive, and contact-based methods. Each has its own strengths and drawbacks. The ideal choice depends on the demands of each use. Let’s see how LVDTs measure up when compared to some alternatives for a few interesting applications.
Position sensing plays a crucial role in ensuring precise control and reliable operation for hydraulic actuation. While Linear Variable Differential Transformers (LVDTs) are the go-to sensing solution, several competing technologies offer various advantages and trade-offs. Today we’ll explore the four main position sensing technologies used in hydraulic actuators:…Read More
Many applications call for LVDTs to be mounted in a pressure vessel. Certain design considerations must be made so the LVDT can still perform well under higher pressures, or when there are subject to significant changes…Read More
Linear position sensors play a critical role in various consumer and industrial applications, quietly supporting functionalities from robotics and automation to electronics and automotive systems. Simply put, these devices convert physical movement into electrical signals, providing valuable position data for control, monitoring, and safety purposes.
LVDTs are versatile, yet relatively simple devices that are used in a wide variety of applications and industries to measure displacement. As such, there are different types of LVDTs available to accommodate their seemingly countless uses. This could be a long discussion, as we could classify LVDTs…Read More
Often, an LVDT installation will require a signal conditioner to convert, process or enhance the generated signals by the sensor. There are lots to choose from on the market, and they are offered with lots of features and options. As a result, we are often asked by customers…Read More
More and more, LVDT buyers find themselves faced with a choice: should they use a stock unit that doesn’t exactly meet their needs, then make accommodations on their end. Or the reverse, have the LVDT modified to meet their specs, thus simplifying production by making installation less complicated….Read More
A linear velocity transducer (LVT), simply referred to as a transducer, is used to measure dynamic velocity. It achieves this by converting velocity into a voltage output. It is a rather simple device that consists of a magnet that moves through a wire coil. In this case, velocity…Read More
Hydraulic actuators are used in a wide range of high-force applications including cranes, excavators, feeder/agitator drives, planes, military vehicles and more. In order to facilitate proper performance for many of these uses, it’s critical to constantly measure position and transmit…Read More
Gaging Linear Variable Displacement Transducers (LVDTs) are used to provide accurate linear displacement measurements for any application that requires a spring-loaded transducer. This alternative design and construction approach is required since a conventional free-unguided LVDT doesn’t always fit the bill. Specifically, they can’t be…Read More
