Measurement of Linear Displacement Using LVDT Trainer ( Digital )

SKU: 3001 Category:


Displacement measurement system demonstrates the principle and working of the specialized dedicated transducer known as ?Linear Variable Differential Transformer ( LVDT )? and also shown is one of its unique application to measure linear physical displacement. A special micrometer arrangement to vary the displacement accurately, a variable excitation source, electronic instrumentation and digital readout all enclosed in a specially designed users friendly elegant powder coated metal cabinet with intelligently designed layout on imported acrylic front panel, are some of its other important features.
