Volvo Speed Sensor The speed sensor of your car is responsible for giving you
the information of how fast or slow your car is by using any of the
speed sensor unit offered in any market including the newest web based
stores. The speedometer gauge, tachometer, cruise control unit and TCU
are the commonly used speed sensors. The speed sensor takes note of the
slowness or fastness of the vehicle by means of the number of
revolution generated by the transmission output shaft. The final output
is the product of the translation of the mechanical rotation into
electronic impulses.
There are various kinds of speed sensors that you
can utilize for your vehicle. One of which is a speedometer. Most auto
speedometers give a value higher than the actual speed to make sure
that the driver or operator will not exceed the legal speed limit which
is usually one of the factors that cause accidents and collisions. The
information it can give may not be as precise as the real speed since
there are several factors that can affect like tire diameter or error
in the transmission. Electronic speedometers come with a computer to
change the interval of pulses into a digital display. The recorded
number of pulses can also be used to determine the distance traveled.
Another type of speed sensor is a tachometer
which is commonly used to determine the speed of the car through the
rate of rotation produced by the crankshaft. The spark rate of the
ignition system is expressed in rpm units. It is a good back up in
choosing the best gear and throttle settings that can match various
types of driving conditions. Its capacity is affected by the speed of
the car. Excess speed especially when used at a long extended driving
hours can cause damage. A replacement like Volvo speed sensor is
available in any on-line store.
