Other types of transducers used in process measurements include mechanical drivers such as gear trains and electrical drivers such as a differential transformer or a Hall effect (semiconductor-based) sensor. [Pg.64]

Active sensors require an external power supply for operation. This is the 5 or 12 V system of the ECU. The main technologies are the complementary metal-oxide semiconductor Hall-effect transducers (CMOS-Hall) or AMR (anisotropic magnetoresistive effect) plus silicon amplification [3],... [Pg.404]

The operation of proximity sensors can be based on a wide range of principles, including capacitance, induction, Hall and magnetic effects variable reluctance, linear variable differential transformer (LVDT), variable resistor mechanical and electromechanical limit switches optical, photoelectric, or fiber-optic sensors laser-based distance, dimension, or thickness sensors air gap sensors ultrasonic and displacement transducers. Their detection ranges vary from micrometers to meters, and their applications include the measurement of position, displacement, proximity, or operational limits in controlling moving components of valves and dampers. Either linear or angular position can be measured ... [Pg.488]
