Measurement of Linear Displacement Using LVDT ( Digital ) 3001

Categories: Instrumentation


ADTRON’S 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.
