Since the output of an inductive sensor has two possible states, an inductive sensor is sometimes referred to as an inductive proximity switch. [2] [3] The sensor consists of an induction loop or detector coil. Most often this is physically a number of turns of insulated magnet wire wound around a high magnetic permeability core, such as a ...
Hall sensors ICs often integrate digital electronics. [26] This enables advanced corrections to the sensor characteristics (e.g. temperature-coefficient corrections), digital communication to microprocessor systems, and may provide interfaces for input diagnostics, fault protection for transient conditions, and short/open-circuit detection.

In some transducers, signal conditioning is integrated with the sensor, for example in Hall effect sensors. In power electronics , before processing the input sensed signals by sensors like voltage sensor and current sensor, signal conditioning scales signals to level acceptable to the microprocessor.
A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic, or photovoltaic that converts one type of energy to another for various purposes including measurement or information transfer (for example, pressure sensors). In a broader sense, a transducer is sometimes defined as any device that converts ...
A VR sensor used as a simple proximity sensor can determine the position of a mechanical link in a piece of industrial equipment. A crankshaft position sensor (in an automobile engine) is used to provide the angular position of the crankshaft to the engine control unit. The engine control unit can then calculate engine speed (angular velocity).
A control loop is the fundamental building block of control systems in general and industrial control systems in particular. It consists of the process sensor, the controller function, and the final control element (FCE) which controls the process necessary to automatically adjust the value of a measured process variable (PV) to equal the value of a desired set-point (SP).
Sensors (detectors) are transducers that react to environmental conditions by changing their electrical properties or generating an electrical signal. The transducers listed here are single electronic components (as opposed to complete assemblies), and are passive (see Semiconductors and Tubes for active ones).
