Position transducers based on the Hall effect are often used in automotive and industrial products because they can provide long life at a relatively low cost. Since the sensitivity of a Hall effect element is based on measuring the magnetic field at a specific point within the device package, a single element provides for a relatively short stroke linear position sensor (less than 25mm stroke). Longer-stroke-length transducers can be made by using mechanical advantage or by incorporating an array of sensing elements, but the benefit of lower cost is then reduced. Hall effect sensors measure

Adapted and expanded to meet all the requirements of motor vehicle NVQs at levels 2 and 3, this book includes numerous features to help the student learn, and relates theory to workplace practice.

As the definitive resource on position sensing technology, Understanding Position Sensors encompasses all aspects necessary for a full understanding of the field, with topics of background, operational theory, design, and application. While grasping the theory of technologies used in the measurement of linear and angular/rotary position sensors, the reader will also learn about terminology, interfacing, testing, and other valuable concepts that are useful in the understanding of sensors in general. 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; specification of position sensors and the effect on performance; and sensor output types, plus an extensive section covering communication protocols. The remaining chapters describe 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, optical triangulation position sensors, and ultrasonic position sensors. Presents sensor specification, theory of operation, sensor design, and application criteria Reviews the background history of position sensors as well as the underlying engineering techniques Includes end-of-chapter exercises Understanding Position Sensors is written for electrical, mechanical, and material engineers, as well as for engineering students who are interested in understanding sensor technologies, and can be used as a textbook for an engineering course on sensor technology.

Automotive technicians must learn how to safely and effectively maintain, diagnose, and repair every system on the automobile. Fundamentals of Automotive Technology provides students with the critical knowledge and essential skills to master these tasks successfully. With a focus on clarity and accuracy, the Second Edition offers students and instructors a single source of unparalleled coverage for every task from MLR through MAST. Fully updated and reorganized, the revised format enhances student comprehension and encourages critical thinking.

Automotive Automatic Transmission and Transaxles, published as part of the CDX Master Automotive Technician Series, provides students with an in-depth introduction to diagnosing, repairing, and rebuilding transmissions of all types. Utilizing a "strategy-based diagnostics" approach, this book helps students master technical trouble-shooting in order to address the problem correctly on the first attempt. -Outcome focused with clear objectives, assessments, and seamless coordination with task sheets -Introduces transmission design and operation, electronic controls, torque converters, gears and shafts, reaction and friction units, and manufacturer types -Equips students with tried-and-true techniques for use with complex shop problems -Combines the latest technology for computer-controlled transmissions with traditional skills for hydraulic transmissions -Filled with pictures and illustrations that aid comprehension, as well as real-world examples that put theory into practice -Offers instructors an intuitive, methodical course structure and helpful support tools With complete coverage of this specialized topic, this book prepares students for MAST certification and the full range of transmission problems they will encounter afterward as a technician. About CDX Master Automotive Technician Series Organized around the principles of outcome-based education, CDX offers a uniquely flexible and in-depth program which aligns learning and assessments into one cohesive and adaptable learning system. Used in conjunction with CDX MAST Online, CDX prepares students for professional success with media-rich integrated solutions. The CDX Automotive MAST Series will cover all eight areas of ASE certification.

Fundamentals of Automotive Technology: Principles and Practice covers crucial material for career and technical education, secondary/post-secondary, and community college students and provides both rationales and step-by-step instructions for virtually every non-diagnosis NATEF task. Each section provides a comprehensive overview of a key topic area, with real-life problem scenarios that encourage students to develop connections between different skill and knowledge components. Customer service, safety, and math, science, and literary principles are demonstrated throughout the text to build student skill levels. Chapters are linked via cross-reference tools that support skill retention, critical thinking, and problem-solving. Students are regularly reminded that people skills are as important as technical skills in customer service fields.
