LVDT Trainer
Scientech LVDT Trainer ST2303 is designed to learn
LVDT Characteristics. LVDT (Linear Variable Differential
Transformer) is the most widely used inductive
transducer for displacement measurement. LVDT is a
secondary transducer which converts the displacement
directly into an electrical output proportional to the
displacement. The trainer has seven-segment LED
display showing displacement in mm with a sensitivity of
10mV/mm in the range of 10mm. ST 2303 is self
contained single box design and easy to use.
