  2. Transmission control unit - Wikipedia

    en.wikipedia.org/wiki/Transmission_Control_Unit

    The transmission control unit (TCU) in older automobiles with a clutchless manual transmission (without a clutch pedal) typically consists of an electrical switch connected to the gearshift, that is activated whenever the internal transmission control unit senses driver touching the gearshift to switch gears, which then primes a sensor or ...

    Crankshaft position sensor (CKP) Curb feeler; Defect detector; Engine coolant temperature sensor; Hall effect sensor; Wheel speed sensor; Airbag sensors; Automatic transmission speed sensor; Brake fluid pressure sensor; Camshaft position sensor (CMP) Cylinder Head Temperature gauge; Engine crankcase pressure sensor; Exhaust gas temperature ...

  4. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    Speed sensors used in automobile transmissions are used to measure the rotational speed (angular velocity) of shafts within the transmission. The engine control unit or transmission control unit (depending on the particular automobile) uses these sensors to determine when to shift from one gear to the next.

  5. Data acquisition - Wikipedia

    en.wikipedia.org/wiki/Data_acquisition

    Various other examples of signal conditioning might be bridge completion, providing current or voltage excitation to the sensor, isolation, and linearization. For transmission purposes, single ended analog signals, which are more susceptible to noise can be converted to differential signals. Once digitized, the signal can be encoded to reduce ...

  6. Smart transducer - Wikipedia

    en.wikipedia.org/wiki/Smart_transducer

    A smart transducer is an analog or digital transducer, actuator, or sensor combined with a processing unit and a communication interface. [ 1 ] As sensors and actuators become more complex, they provide support for various modes of operation and interfacing.

  7. 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.).

  8. Digital sensor - Wikipedia

    en.wikipedia.org/wiki/Digital_sensor

    A digital sensor is an electronic or electrochemical sensor, where data is digitally converted and transmitted. Sensors are often used for analytical measurements, e.g. the measurement of chemical and physical properties of liquids. Examples of measured parameters are pH value, conductivity, oxygen, redox potentials.

  9. Signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Signal_conditioning

    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.
