  2. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    A variable reluctance sensor (commonly called a VR sensor) is a transducer that measures changes in magnetic reluctance. When combined with basic electronic circuitry, the sensor detects the change in presence or proximity of ferrous objects. With more complex circuitry and the addition of software and specific mechanical hardware, a VR sensor ...

  3. Ultrasonic transducer - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_transducer

    Ultrasonic transducer. A linear array ultrasonic transducer for use in medical ultrasonography. Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters ...

  4. Highway Addressable Remote Transducer Protocol - Wikipedia

    en.wikipedia.org/wiki/Highway_Addressable_Remote...

    The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems. HART is widely used in process ...

  5. Log-space transducer - Wikipedia

    en.wikipedia.org/wiki/Log-space_transducer

    In computational complexity theory, a log space transducer (LST) is a type of Turing machine used for log-space reductions . A log space transducer, , has three tapes: A read-only input tape. symbols). A write-only, write-once output tape. will be designed to compute a log-space computable function (where is the alphabet of both the input and ...

  6. Speed wobble - Wikipedia

    en.wikipedia.org/wiki/Speed_wobble

    Speed wobble. Wobble, shimmy, tank-slapper, [1] speed wobble, and even death wobble are all words and phrases used to describe a quick (4–10 Hz) oscillation of primarily just the steerable wheel (s) of a vehicle. Initially, the rest of the vehicle remains mostly unaffected, until translated into a vehicle yaw oscillation of increasing ...

  7. Potentiometer - Wikipedia

    en.wikipedia.org/wiki/Potentiometer

    The 'log pot', that is, a potentiometer has a resistance, taper, or, "curve" (or law) of a logarithmic (log) form, is used as the volume control in audio power amplifiers, where it is also called an "audio taper pot", because the amplitude response of the human ear is approximately logarithmic. It ensures that on a volume control marked 0 to 10 ...

  8. Sensor - Wikipedia

    en.wikipedia.org/wiki/Sensor

    Sensor. A sensor is a device that produces an output signal for the purpose of detecting a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor.

  9. Eddy-current sensor - Wikipedia

    en.wikipedia.org/wiki/Eddy-current_sensor

    Eddy-current sensor. Eddy current sensor s uses the principle of eddy current formation to sense displacement. These sensors measure shaft displacement in rotating machinery and have been around for many years as they offer manufacturers high-linearity, high-speed measurements, and high resolution. [1]
