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

Without sensors most electronic applications would not exist—sensors perform a vital function, namely providing an interface to the real world. Hall effect sensors, based on a magnetic phenomena, are one of the most commonly used sensing technologies today. In the 1970s it became possible to build Hall effect sensors on integrated circuits with onboard signal processing circuitry, vastly reducing the cost and enabling widespread practical use. One of the first major applications was in computer keyboards, replacing mechanical contacts. Hundreds of millions of these devices are now manufactured each year for use in a great variety of applications, including automobiles, computers, industrial control systems, cell phones, and many others. The importance of these sensors, however, contrasts with the limited information available. Many recent advances in miniaturization, smart sensor configurations, and networkable sensor technology have led to design changes and a need for reliable information. Most of the technical information on Hall effect sensors is supplied by sensor manufacturers and is slanted toward a particular product line. System design and control engineers need an independent, readable source of practical design information and technical details that is not product- or manufacturer-specific and that shows how Hall effect sensors work, how to interface to them, and how to apply them in a variety of uses. This book covers: • the physics behind Hall effect sensors • Hall effect transducers • transducer interfacing • integrated Hall effect sensors and how to interface to them • sensing techniques using Hall effect sensors • application-specific sensor ICs • relevant development and design tools This second edition is expanded and updated to reflect the latest advances in Hall effect devices and applications! Information about various sensor technologies is scarce, scattered and hard to locate. Most of it is either too theoretical for working engineers, or is manufacturer literature that can’t be entirely trusted. Engineers and engineering managers need a comprehensive, up-to-date, and accurate reference to use when scoping out their designs incorporating Hall effect sensors. * A comprehensive, up-to-date reference to use when crafting all kinds of designs with Hall effect sensors *Replaces other information about sensors that is too theoretical, too biased toward one particular manufacturer, or too difficult to locate *Highly respected and influential author in the burgeoning sensors community

The need for both intrinsic and extrinsic fiber optic sensor technologies continues to grow. To meet the demands of this fast expanding applications-driven market, Fiber Optic Sensors, Second Edition presents both the latest advances in fiber optic sensor technology, such as the application of photonic crystal fibers to fiber optic gyroscopes, and recent application opportunities, including the use of fiber optic sensors as a minimally invasive medical treatment. The new edition of this seminal work highlights the development of fiber optic sensors, while providing an overview of current methods for the construction of high-speed and high-capacity fiber optic systems. Two new chapters cover topics such as femtosecond laser illumination inscription and the growing application sector of fiber optic chemical and biological sensors. Adding significant new material, the book continues to provide a progressive history of each sensor type as well as basic principles and fundamental building blocks for practical applications in the electrical aerospace, defense and manufacturing, smart structure, undersea surveillance, medical, and gas and oil industries.

The first thoughts in designing an inexpensive position transducer often involve an inductive type of sensing element. This is because they can be simple in theory, as the basic sensing element is made from one or more coils of wire, together with a movable core (see Figure 5.1). In some applications, though, an acceptable trade-off among cost, performance,

Magnetostrictive position transducers are noncontact, absolute reading, and have essentially infinite resolution. Linear transducers are commercially available with a nonlinearity of less than .01% and full-scale ranges from less than 10mm to over 20m [24]. Curved and rotary sensors are possible. Popular applications include industrial machinery, such as injection molding machines and hydraulic cylinders, as well as automotive and commercial products. The coupling between the moving and stationary parts of the transducer
