ST2303 Technologies Pvt. Ltd. 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. ¨ ¨ ¨ ¨ ¨ Technical Specifications Experiments that can be performed Measurement Range : 20 mm (±10 mm) Excitation Frequency : 4 KHz (approx.)
