This third edition of Sensors and Transducers has been thoroughly revised to take account of the ever-increasing role of these components and of improvements in design. New tables of properties and illustrations have also been added.
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.
29 Δεκ 2019 · Sensors and transducers. In this book Ian Sinclair provides the practical knowhow required by technician engineers, systems designers and students. The focus is firmly on understanding the technologies and their different applications, not a mathematical approach.
Pressure sensors, resistance temperature sensors, thermistors, strain gauges and photoresistors are examples of sensors, because they are supplied with electrical energy and give an electrical signal when subjected to a stimulus (Fig. 2.1b).
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
Definitions: Transducer and sensors. Transducer. a device that converts a primary form of energy into 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.
This learning module is one of three SCME modules that discuss the types of components found in microelectromechanical systems (MEMS). This module covers “transducers” – what they are, how they work and how they are used in both macro and micro-sized systems.
