The speedometer is the ideal instrument for lovers of speed , for those who like to know when to play with speed and that for others it often goes unnoticed. However, the important thing here is that every vehicle has a speedometer to perform its functions.

But how much is really known about this instrument? Perhaps very little, because it really has many more features to offer than being a simple speed meter.

To make a fair tribute, I invite you to continue reading the next few lines, to learn about all the aspects that this instrument has and that can serve you in your daily life.

What is a Speedometer?

As its name states, a speedometer is an instrument that has the ability to measure the average and total speed that a vehicle is having as it moves.

It is present in any object that has a motor and wheels, as it is necessary to know the speed levels it has.

In addition, you have to know that in all the vehicles that works, it works synergistically with the odometer or odometer, you can know the speed by kilometers per hour or miles per hour.

What is a speedometer for?

A speedometer has as its only function, the measurement of speed levels using for this the information of the movement of the wheels and the internal turns of all its machinery.

However, it can be used for other tasks when connected to other instruments. For example, with the odometer since it is necessary to record those kilometers counted by the speedometer but in the aspect of distance.

How does a speedometer work?

The operation of the speedometer will depend directly on the model, because at the beginning they worked by a mechanical system, that is, when the wheels turned they sent the information through a cable and then the speedometer quantified this data.

Currently as almost all speedometers are electronic , I will detail you even more what it is about.

Internally they have a sensor that is capable of perceiving the rotation and upon feeling them begins to generate electrical impulses that are directly proportional to the speed of rotation of the wheels on the vehicle.

Then an internal computer converts those pulses received into a figure as such, which it sends to a digital screen to show the results, although there are models that maintain the analogue system and what the PC does is send them so that the needle moves from mechanical way.

Speedometer uses

The uses of the speedometer are exclusively intended for the world of motors, because this is where they can really work and where there is a linear speed in itself.

This is why the automobile, aeronautical and shipping industries, among others, use this element to include it in the products they make, as it is currently a fundamental requirement for operation and even for legal statutes.

Speedometers have been transcendental despite being a very recent instrument, this is due to this potential quality they have, which is so necessary in any object driven by wheels.

Speedometer Types

The speedometers present a wide variety that agrees to a great extent, with the application they have in vehicles or means of transport in general, since it is a vital piece, when quantifying speeds that it has in a given distance. Speedometers are classified into:

  • According to its operating mechanism:

It refers to the degree of internal technology that this speedometer has, to be able to reflect the result of its measurement.

Mechanical speedometer

In this case, it works with the number of turns made by the wheels, the information is sent to the gearbox, by a metallic cable . This is also received by the speedometer, which it does is transform into numbers to know exactly what it is.

Electronic speedometer

They are a recent model, as it uses sensors and microprocessors, to be able to make measurements, almost all speedometers currently use this technology, to the point of discontinuing those of a mechanical nature.

  • Based on how they represent your results

Once its operating mechanism is activated, the result can be reflected on a scale by needle or on a screen, digitally.

Analog Speedometer:

It uses a system of needles for speed marking, since a force is generated internally, capable of pushing the needle in relation to the magnitude of said force

digital speedometer

After doing the measurement electronically to be able to display the results on a screen and digitally.

  • According to the place where they work

Despite being broadly the same speedometer, they can be found under other names, according to the type of vehicle in which it is.

Motorcycle speedometer

In this case, it is a smaller model, which is coupled to the capacity of the engine and to be two-wheeled. But, the function remains the same.

Car speedometer

It is the one that is commonly found on the dashboard of the car and is linked to the odometer, to be able to make the measurements of the speed and the mileage traveled with the vehicle.

Pit log in boats

It is the name given to speedometers in boats , in this case they do not measure kilometers but nautical miles , among other measurement parameters, but the operating mechanism remains the same.

Flight speed indicator for airplanes

This is the one found in the flight deck, where the pilot can see how fast the plane is flying, which is important to stabilize it once it is in the air.

Anyway, speedometers have evolved a lot since their creation, which is interesting, since we see that they have a fairly wide applicability in the world of motors, to the point that there are even built-in GPS speedometers.

Speedometer Features

The speedometer has a number of main characteristics, which define in itself all the properties it has and why it has become such an important element in the world today. The main ones being:

  • They work with immediacy, that is, the records shown are in real time and any change reflects it almost automatically.
  • The interval that is measured by this speed is very small, which is why they have a minimum margin of error .
  • They are internally controlled by a resistor and covered by a transmission system.
  • It measures in miles per hours, nautical miles, kilometers per hour, among other units of measurement , which vary according to the regulations of the country where it is operating.
  • Speedometers differ in their measurement ability , according to how fast a certain vehicle can reach, for example, there are 180km / h, 200km / h, 220km / h and so on.
  • They may have GPS included .
  • Any modification unrelated to the vehicle, especially in the wheels, may vary the accuracy of the speedometer, for example, when wheels that do not correspond to its size are fitted.

Among others, which is extremely important when talking about a speedometer, as it allows us to understand how it works and to be able to use it in a better way.

Importance of the Speedometer

The importance that the speedometer currently has, lies in the fact that it provides useful information for the driver , since it tells him what his speed is and thus he will take the measures to increase or decrease it.

In addition, it can function as a safety agent, due to the fact that seeing the speed, you can slow down at any given time to stay within the laws or stay in a proper one, which is vital in preventing accidents.

It allows carrying out studies related to the capacities of the engines, because when they are creating a new one, they tend to test it with the speedometer to determine if it reaches the desired speed.

History of the Speedometer

The history of the speedometer specifically begins in 1888, when an inventor named Josip Belusić created this instrument . It is not until four years later, that it was patented by the great Otto Schulze, for it to come out to the light and knowledge of the world.

The speedometer grew in tandem with the specialization and speed of the engines, since in the 20th century, vehicles were already capable of greatly exceeding horsepower, and laws were even created to regulate speed.

However, at that time, speedometers used mechanized systems, it was not until 1993 that the electronic speedometer came to the world and with it all its benefits and technology, seizing the hearts of the automobile industries, which began to replace the mechanical one with it. new.

I am a person with great restlessness and curiosity to learn, discover what I do not know, as well as reinvent myself daily, someone who is curious about life and wants to know. I enjoy sharing knowledge.
This is my personal project but I also collaborate in other blogs, it is the case, the most important web on water currently exists in the US, if you are interested you can read my articles here.
