Level Controller Using Inductive Transducer Trainer

SKU: 3023 Category:


Level measurement and control system demonstrates the principle and working of a specialised dedicated Inductive type level transducer known as Linear Variable Differential Transformer (LVDT) and shown here is one of its unique application to measure level accurately. A special arrangement of float ball coupled with LVDT is used to measure level continuously, an excitation source, electronic instrumentation for control and digital readout all enclosed in a specially designed users friendly elegant powder coated metal cabinet with a well spread intelligently designed circuit layout on imported acrylic front panel, are some of its other important features.
