ST Series
LVDT
The ST series AC-LVDTs are layer wound on a steel coil form, providing high quality and rugged position sensors.
Featuring large radial clearance between case hole and core. Steel casing serves as electromagnetic and electrostatic shielding. Being an AC LVDT it needs a signal conditioner to operate it, such as LVDT Signal Conditioner model EL-10 or LVDT Signal Conditioner model EL-35, or LVDT Control Box CB-100 Series,
or USB-10 Unit. All are manufactured by Singer Instruments & Control.
