Timer

November 1, 2021

Time has always been a highly relevant variable for humanity; many efforts were made to measure it. Throughout history , a large number of instruments have been created to fulfill this long-awaited task, one of the main being timers.

This measuring instrument is an evolution of the hourglass, since it has the same function of counting the time that has elapsed, during a given process or phenomenon.

However, when listening to the word timer, you have to understand that it is a very broad concept, that is why in the next few lines I will explain what this instrument is about.

What is a Timer?

The timer is also known as the minute hand . What differs from others is that it is programmed to be able to count exactly the minutes that are desired.

This instrument has a counter inside, which is responsible for measuring the minutes that have elapsed, in addition, it has an alarm that turns on when the programmed time is reached.

Many define the timer as a relay , since it allows the connection and disconnection in an electrical system to be controlled, which allows the connection or disconnection to be controlled, this for a certain time.

A relay is a device that works with an electromagnetic field and with the help of a magnet and a coil is capable of activating or turning off electrical circuits, as if it were a switch.

What is a Timer for?

A timer is nothing more than a tool that counts time and that we program it, so that it activates in the time needed as if it were the alarm on our phone.

This is why I can tell you that this instrument has a regulating function, which controls the times in such a way that you can activate or deactivate a circuit, according to it.

How does a Timer work?

The timer will vary in its operation, taking into consideration the type of timer it is. However, there are common qualities that can be grouped together to try to explain how it works.

First of all, it must be understood that it works mainly with a relay, which generates a magnetic field that provides it with energy so that it can, through many mechanisms, activate or deactivate the operation.

In addition, it receives voltage signals, which drives the relay itself to perform its function and in the end it will exchange the contacts, add the signals and thus comply with the programmed amount of time.

Once the system complies with its programming, it will activate an alarm, which will notify people that the time has already been reached.

Timer uses

The timer is an extremely useful tool for many aspects of research, it even plays an important role in everyday activities.

The most prominent uses of the timer are as follows:

  • It is a vital piece in biology and medicine laboratories for the control of time, in exposure processes related to enzymatic digestion.
  • It is used in laboratory spaces , to program the time it will take for a reaction to appear, which when the time expires an alarm will go on telling the laboratory staff that the waiting time has already expired.
  • It is used as a security and control tool in homes, businesses, companies and laboratories. Because, it allows the lights, that the electrical appliances, devices or machinery, to be disconnected after a specific time has elapsed.
  • In the kitchen, it is an essential element to be able to control the cooking, cooling and baking times of different foods.

It is definitely a tool that you should not stop trying, it can be an excellent helper to keep track of time, in the different tasks you perform.

Timer Types

This instrument has a large number of types, which are divided according to the function they fulfill and even their structure in general. This is important as there is a timer for every situation.

The types of timer are as follows:

  • Timer on connection

This is the name given to any timer that is going to receive a high voltage signal and then connects, after waiting for a delay time, to the network. In this process the contacts are exchanged and it can be adjusted with another instrument, known as a potentiometer.

  • Timer at switch-off

It is the opposite of the connection timer, because it will stop receiving this high voltage signal and then after a certain time it will exchange these contacts.

  • Electronic timer

This type of timer uses a resistor that allows you to turn on or off a capacitor that you have internally. This relay system works with a coil that is turned on through electric current. In this case, this timer is stabilized through diodes.

  • thermal timer

This model of timer uses a double sheet of metal, which gives it that thermal character. The internal transformer has two arms, the first is connected directly to the network, while the second is connected to the sheet, generating short circuits and thus being able to heat the sheet, which is why it is known as a thermal timer.

  • magnetic timer

This timer uses a particular system, a thin copper tube is embedded in the core of the relay, that is, where all the magnetic field of the magnet that accompanies the relay is generated, forming a sleeve that can be positioned in front or behind.

  • Pneumatic timer

This timer uses a popular tool in pneumatics, the bellows. What the magnet that contains the relay is going to do is actuate this bellows, causing it to be compressed. Then, as we know, this bellows is going to fill with air, causing its recovery to change and therefore the timing.

  • Engine timer

This timer is powered by a motor and an electromagnetic field, driving a clock system for timing. Once a relevant time has elapsed, the overall system will be activated or deactivated.

  • Timer for starters

It has a star contact that receives a tight signal and after a while it closes, then another time passes and it opens. Once opened, a new pause occurs that will allow it to connect to the contact and thus be able to time.

Despite all the differences that may exist with these instruments, you can see that it is basically the same with different elements, because they activate and deactivate receiving signals with a significant voltage load.

Timer Features

The timers have a series of particular characteristics , being a unique instrument with an innovative system. This is why I wanted to bring you the main ones so that you can identify the correct one, which are:

  • The timer is controlled inside by
  • It is universal, as it can read all frequencies and voltages on the entire planet.
  • Its timing reading system is very easy to interpret.
  • The operation they perform will last the time for which it is programmed and will do so with high precision.
  • Regulate is the connection and disconnection for a certain amount of time, of a circuit as such.
  • The assembly of the entire structure and its stability is very easy to achieve.

It is a simple system, what happens is that it sounds complicated when naming all those pieces, so you should not worry since it is extremely practical and effective to carry out its work.

Timer Importance

The timer, although for many years it was kept in hiding or under the shadow of chronometers , the reality is that today they are highly valued elements.

This instrument has allowed people to have a more exhaustive control of all processes, phenomena, device activity, among others. Offering precision, security, practicality and stability.

Time has been a transcendental variable and that is why you must apply all the necessary tools to give it a fair tribute, especially the timer.

Born and raised in Brussels in an English family, I have always lived in a multicultural environment. After several work experiences in marketing and communication, I came to Smart Water Magazine, which I describe as the most exciting challenge of my career.
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.
