Definitions: Transducer and sensors • Transducer – a device that converts a primary form of energy in to a corresponding signal with a different energy form Primary Energy Forms: mechanical, thermal, electromagnetic, optical, chemical, etc. • Sensor (e.g., thermometer) - is a device that detects a change in a physical
Lecture 1 Sensors and transducers Measurement is an important subsystem of a mechatronics system. Its main function is to collect the information on system status and to feed it to the micro-processor(s) for controlling the whole system. Measurement system comprises of sensors, transducers and signal processing devices.
Describe common methods for converting a physical parameter into an electrical quantity and give examples of transducers, including those for measurement of temperature, strain, motion, position and light. Explain how to make sensitive measurements using a Wheatstone bridge, including balancing and offset compensation.

sensors need to be calibrated against known standards. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base. There are also innumerable applications for sensors of which most people are never aware.
Displacement, position and proximity sensor. Displacement sensors are concerned with the measurement of amount by which some object has moved. Position sensors are concerned with the determination of the position of some object with rereference to some reference point. Proximity sensors are a form of position sensors.
Our Sensors and Transducers tutorials will guide you to learn the principle and working of different types of sensors and transducers easily. A sensor or transducer is a device that gives a usable output in response to a specified measurand.
