Many engineering applications and systems depend on accurate measurements and monitoring. Transducers are fundamental to the measurement process, consequently the study of different types of transducers, how they operate and how their output signals can be processed, is essential knowledge for engineers. The Transducers Kit introduces students to the concepts and understanding of common transducer devices and standard signal conditioning methods via 28 excellent practical assignments. It comprises the Measurements Package, the Electro-mechanical Transducers Kit, the Heat Transducers Kit, the Light Transducers Kit, the Power Supply and includes all leads, accessories and courseware. The measurements package is an instrumentation module with signal conditioning circuitry and includes a Wheatstone bridge, oscillator, operational amplifier, discriminator and power amplifier. The electro-mechanical kit includes 6 linear displacement transducers, namely a linear variable resistor, variable inductor, variable area capacitor, linear variable differential transducer (LVDT), variable distance capacitor and a strain gauge. The heat transducers kit includes 4 thermal devices and a heat bar assembly with temperature gradient. It includes a thermistor, platinum resistance, a bi-metallic strip and thermocouple. The light transducers kit comprises a light source, photoconductive cell, photodiode and phototransistor. A power supply, leads and theory and experiment manual with 28 comprehensive assignments completes transducers teaching kit.
