01.Winding Structure

The winding structure is chosen depending on the Electrical Stroke. If the electrical stroke is less than +/- 5 mm, it is preferable to apply “Three Stage Winding”. If the electrical stroke is more than +/- 5 mm, the suitable structure is “Taper Winding”.

Electrical Stroke

The electrical stroke is the range of displacement which all performance requirements specified in the specifications can be satisfied.
In general, it is indicated by +/- on both sides of Extend and Retract of the probe centered on the Null position, and is called "Full Scale (F.S.)" for the entire width of the linear range.

Three Stage Winding

The simplest structure with secondary coils placed on both sides of the primary coil. Easy winding.

Taper Winding

The primary coil is placed over the entire winding width of the coil. The secondary coil is crossed and overlapped to form a tapered shape on the outside of the primary coil.

02.Tamagawa LVDT Lineup

LVDTs have quite different forms depending on the specifications of stroke length (position detection range) and the installation environment.
Tamagawa LVDTs have a long experience in aircraft applications and we have a wide variety of products in our lineup.

03.Production Processes

Tamagawa Group has an integrated / in-house processes for LVDT, from Design & Development, Special Processes, Assembly to Inspection.
This in-house production enables to shorten production lead time and makes it easier to manage the overall production processes.
