Overview of T-750 Series LVDT Position Sensors

The T-750 series of free core linear position sensors from Harold G. Schaevitz Industries offer reliable long-life operation utilizing LVDT linear variable differential transformer technology.

T-750 series LVDTs are versatile devices that are used in a wide range of commercial and industrial gauging applications, including dimensional gauging of machined parts, gap distance measurement, and manufacturing process control.

T-750 series free core LVDTs consist of a coil body and separate core.  The coil body is generally held stationary in a fixture and the core is mechanically coupled to the object under test using a core extension rod.  As the linear position of the object under test changes, the core travels within the coil body and the LVDT produces a corresponding electrical signal that is proportional to the change in position.

T-750 series LVDTs have a 0.750 inch (19 mm) O.D. stainless steel coil body with 12 inch length Integral wires.

T-750 series LVDTs are available in measuring ranges from 0.1 inch (2.5 mm) up to 20 inches (508 mm).

The “A” series is an AC version which requires an external signal conditioning amplifier.
The “D” series is internally amplified with a +/- 10 VDC output.
The “E” series is internally amplified with a 0 to 10 VDC output.
The “I” series is internally amplified with a 4 to 20 mA output.
