Timer: characteristics, prices, uses …

November 2, 2021

timer , in general terms, is an instrument with which time can be measured in a specific and exact way, which defines it in a common way as a measuring instrument capable of being used in a large number of circumstances of daily life. and in the professional field.

The main function of a timer is to keep track of time, which helps to establish patterns and numbers based on an action or activity. According to its history, this tool was derived from the evolution of hourglasses, which were created for the same purpose.

Currently, timers can be defined broadly, as their uses, types, and characteristics tend to be more detailed. Therefore, below we expand the information with luxuries and details.

What is a timer?

The timer is a widely used tool in various fields, including the ease that it is included in modern gadgets, such as smartphones. However, in these cases, although its function is the same, its mode of use is different.

It is sometimes referred to as a timer or relay , depending on the way it is known in certain countries. This happens because through the timer, an estimated time can be programmed that helps to freeze an activity during it, having an alarm that warns when the time has elapsed.

Within the conventional timers, there is a counter, which allows the time to be precise and to measure it, in minutes, hours and seconds, so that the device counts with precision. This detail has led to this tool being used in various professional fields, such as physics and chemistry laboratories.

Timer features

Timers are not the only tools to keep track of time, so it is important to take into account their exact characteristics so that there is no confusion between them. In themselves, these handle a completely unique and evolved system that differentiates it from other systems used to measure time, so it is important to know it in detail.

The main features of the timer are the following:

  • A timer is considered as a universal device, capable of understanding and analyzing any type of frequency and voltage worldwide, including planetary situations.
  • It has a system at a glance that is simple enough to be quickly interpreted by a professional, without affecting its function in terms of complexity.
  • Its precision is impressive, so that the time you regulate it will be the exact time that will elapse. This is because it works with a system that is programmed and reprogrammed according to the needs of individuals.
  • It works as a regulator of connection and of disconnection, that works in terms of a certain time.
  • It can be found in models that are very simple to structure, with few pieces and great details.
  • It is a practical, comfortable and efficient device.

How does a timer work?

Although a timer generates the same result, not all of them work in the same way since each of them has different specifications and details, depending on the type of timer in question. However, in general, there are some features that work in the same way in all of them, so there is a basic explanation regarding their operation that adapts to all timers.

Any timer works internally with a relay , which is why in some countries this tool is known by this name. A relay is a small device that produces a magnetic field that generates the energy necessary for the timer to work. That is, it helps it begin and end when it is stipulated in advance.

On the other hand, the timers have voltage signals that are the same that allow the relay to execute its function on all occasions, which ends up allowing the programmed time to be fulfilled. Finally, when this happens and the time passes, an internal alarm will sound warning that the timer has finished its task.

What is a timer used for?

As it is a tool capable of measuring time in a specific situation, this makes it very useful in terms of any circumstance and area of ​​life itself. However, it tends to be highly used in research situations, as its precision helps to always maintain excellent results.

The most common general uses of a timer are as follows:

  • It is a highly used and important tool for laboratories of any kind, including medical, biological, physical and chemical research.
  • Regarding a more specific use and breaking down the previous point, in some laboratories it tends to be used in order to establish a precise time regarding a reaction, since in this way the time is unknown and it is capable of being discovered thanks to the timer . If not, the alarm is set and it will sound once the estimated time expires and the results are observed.
  • As for daily life, a timer works in any corner, especially in the field of security, and it is that it helps devices of any type of program to turn off, err or activate, including garages, alarms, electrical appliances and more.
  • And of course, it is highly used in the kitchen since large recipes require estimated times for them, so that they are at the exact point. Therefore, it helps in any area of ​​the kitchen, including baking.

On the other hand, it is often used when exercising, to carry out work or simply to find out how long it takes to carry out a common activity.

Timer Types

As we have seen in previous sections, although a timer is a general device, it is divided into various types, which in turn are classified thanks to their structures and functions. Therefore, a special timer is achieved for each situation.

The main types of timer are the following:

Timer on connection

The connection timers are those that are characterized by receiving the high voltage signal that we have mentioned in previous sections, in order to finally connect to the network. It is a very common type of timer used in laboratories.

Timer at switch-off

As its name indicates, this type of timer works in the opposite way to the previous one since it stops receiving the high voltage signal and then it will exchange the contacts.

Electronic timer

As its name mentions, this type of timer is one that it uses working with an electric current, using a resistor that allows the capacitor inside it to be turned on or off.

thermal timer

The term timer gets its name thanks to the fact that it makes use of a double sheet of metal, which generates that it manages to carry out its process, which in turn works with two arms, where one of them is kept connected with the foil and the other with the net. In this way, the sheet manages to heat up and carry out its task.

magnetic timer

A magnetic timer is quite peculiar, since although it generates the same results as the previous ones, it works with a very thin copper tube that is embedded inside the relay, specifically in its core, which produces the magnetic field.

Pneumatic timer

The pneumatic timer also has a very particular operation, since it makes use of a bellows, which is activated thanks to the magnet that the relay has. In this way, compression begins to occur and the bellows will fill with air, until finally the minute counting process will start.

Engine timer

As its name lets us know, this tool has a motor that helps the timer start, aided by the clock system that it has inside. The engine tends to be automatic and only works when it deserves it, otherwise, it will remain in a state of rest.

Timer for starters

Finally, there is the timer for starters, which is the one that has a star contact, which is responsible for receiving all the high voltage signal to open and start the timing process.

Advantages and importance of the timer

In general terms, today the timer is considered as a tool full of importance that for years was hidden behind the stopwatches.

However, thanks to the fact of allowing thousands of people to be able to specify the time of some action, or failing that, to maintain precise control in any activity that is unlikely at first glance, it has led to it being classified as a highly important and valuable tool. value currently.
