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.

Data are collected from an object by a number of sensors. Some of them (2, 3, and 4) are positioned directly on or inside the object. Sensor 1 perceives the object without a physical contact and, therefore, is called a noncontact sensor. An example of such a sensor is a radiation detector and a TV camera.

The differences between sensors and transducers are often very slight. A sensor performs a transducing action, and the transducer must necessarily sense some physical quantity. The difference lies in the efficiency of energy conversion. The purpose of a sensor is to detect and measure, and whether its efficiency is 5% or 0.1% is almost ...
