  2. Vibration-powered generator - Wikipedia

    en.wikipedia.org/wiki/Vibration-powered_generator

    Sensors in inaccessible places can now generate their own power and transmit data to outside receivers. [2] The generator was developed to be used in air compressors, and is able to power things in high vibration environments like sensors on machinery in manufacturing plants, or sensors that monitor the health of bridges.

  3. Data acquisition - Wikipedia

    en.wikipedia.org/wiki/Data_acquisition

    A sensor, which is a type of transducer, is a device that converts a physical property into a corresponding electrical signal (e.g., strain gauge, thermistor). An acquisition system to measure different properties depends on the sensors that are suited to detect those properties.

  4. Control loop - Wikipedia

    en.wikipedia.org/wiki/Control_loop

    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).

  5. Inductive sensor - Wikipedia

    en.wikipedia.org/wiki/Inductive_sensor

    [2] 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 ...

  6. Transducer - Wikipedia

    en.wikipedia.org/wiki/Transducer

    A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).

  7. IEEE 1451 - Wikipedia

    en.wikipedia.org/wiki/IEEE_1451

    IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...

  9. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    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).
