Types of LVDT
Linear Variable Differential Transformers (LVDTs) can be of many types based on their construction, size, and specific applications. Here are some common types:-
- AC LVDT: The AC LVDT is the most common and most used type of LVDT which operates on the principle of electromagnetic induction (EMI) with AC as an input. AC LVDTs are widely used for displacement measurement in various industrial applications.
- DC LVDT: This type of LVDT operates with a DC (direct current) input. These types of LVDTs are used in limited applications where a DC power source is more convenient.
- Miniature LVDT: This type of LVDT is small in size as the name suggests miniature and its stroke length is small but highly precise. There is Subminiature LVDTs also even smaller in size and best for limited-space applications.
There can be many more LVDTs based on the requirement of the application like High-Temperature LVDTs, Digital LVDTs, or Heavy-Duty High-Frequency Response LVDTs.
Linear Variable Differential Transformer (LVDT)
The LVDT stands for Linear Variable Differential Transformer. It converts the Linear motion into an electrical signal using an inductive transducer. Due to its superior sensitivity and accuracy over other inductive transducers, the LVDT is extensively used in many different fields. For measuring linear distance, the linear variable differential transformer (LVDT) is a precise and trustworthy tool. Today, LVDTs are used in computerized manufacturing, robotics, avionics, and machine tools, combining research facilities, high-level analysis, and analysis to detect damage caused by massive rock deformation or other movements in the subgrade of old buildings or structures. physical structure. One try. This method is used to try to detect failure in concrete slopes and warn or correct the condition. One of the special problems with historical buildings is that they can easily be damaged by small deformations in the long run.
