Chapter 2

Practical Transducers

In the last chapter we examined the physics of a Hall-effect transducer and related its performance to physical characteristics and materials properties. While this level of detail is essential for someone designing a Hall-effect transducer, it is not necessary for someone attempting to design with an already existing and adequately characterized device.

2.1 Key Transducer Characteristics

What are the key characteristics of a Hall-effect transducer that should be considered by a sensor designer? For the vast majority of applications, the following characteristics describe a Hall-effect transducer’s behavior to a degree that will allow one to design it into a larger system.

• Sensitivity

• Temperature coefficient ...
