Download or read book Some Limitations on the Use of Damping in Short Pressure Points written by Ted W. Nyland and published by . This book was released on 1971 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analytical study described in this report examines changes in the useful frequency response of short pressure probes resulting from variations in the viscous damping within the probe tube. The study is based on the use of the Bergh and Tijdeman recursion formula, which was modified to allow the addition of arbitrary amounts of viscous loss in any tube section. Results show that the useful response range can be increased with damping but is dependent on the operating temperature and pressure levels. At 300 K, only a 15-percent variation in average pressure is allowable if the useful response is to be a factor of three higher than that of an undamped probe. This variation increases to 20 or 30 percent at temperatures above 600 K. A computer program based on the modified recursion formula is given in an appendix.

Available in PDF, EPUB and Kindle. Book excerpt: Since publication of the previous, the 3rd edition of this book, the sensor tech- logies have made a remarkable leap ahead. The sensitivity of the sensors became higher, the dimensions – smaller, the selectivity – better, and the prices – lower. What have not changed, are the fundamental principles of the sensor design. They still are governed by the laws of Nature. Arguably one of the greatest geniuses ever lived, Leonardo Da Vinci had his own peculiar way of praying. It went like this, “Oh Lord, thanks for Thou don’t violate Thy own laws. ” It is comforting indeed that the laws of Nature do not change with time, it is just that our appreciation of them becomes re?ned. Thus, this new edition examines the same good old laws of Nature that form the foundation for designs of various sensors. This has not changed much since the previous editions. Yet, the sections that describe practical designs are revised substantially. Recent ideas and developments have been added, while obsolete and less important designs were dropped. This book is about devices commonly called sensors. The invention of a microprocessor has brought highly sophisticated instruments into our everyday life. Numerous computerized appliances, of which microprocessors are integral parts, wash clothes and prepare coffee, play music, guard homes, and control room temperature. Sensors are essential components in any device that uses a digital signal processor.

Book excerpt: A resource on position sensor technology, including background, operational theory, design and applications This book explains the theory and applications of the technologies used in the measurement of linear and angular/rotary position sensors. The first three chapters provide readers with the necessary background information on sensors. These chapters review: the working definitions and conventions used in sensing technology; the specifications of linear position transducers and sensors and how they affect performance; and sensor output types and communication protocols. The remaining chapters discuss each separate sensor technology in detail. These include resistive sensors, cable extension transducers, capacitive sensors, inductive sensors, LVDT and RVDT sensors, distributed impedance sensors, Hall Effect sensors, magnetoresistive sensors, magnetostrictive sensors, linear and rotary encoders, and optical triangulation position sensors. Discusses sensor specification, theory of operation, sensor design, and application criteria Reviews the background history of the linear and angular/rotary position sensors as well as the underlying engineering techniques Includes end-of-chapter exercises Position Sensors is written for electrical, mechanical, and material engineers as well as engineering students who are interested in understanding sensor technologies.
