Possibly you are right now collecting information about temperature sensors for your machinery. You may know what your role is, but it's not yet clear what types of temperature sensors<\/strong> exist. Knowing the types of temperature sensors will help you to know which is the most appropriate when installing one of these systems in your company.<\/p>

Therefore, in the following post we will solve all your doubts: what types of temperature sensors<\/strong> exist, what are the differences between a thermostat and a temperature sensor<\/strong> and which of these sensors is the most recommended and used at this time.<\/p>

Stay with us to resolve all these issues. Let's start:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A temperature sensor is a system that detects variations in air or water temperature and transforms them into an electrical signal that is sent to an electronic system. This signal triggers specific changes in that electronic system to regulate the temperature.<\/p>

Also known as a temperature probe, this sensor is mainly composed of three parts. First, and obviously, it has a sensing element (the types of which we will discuss in this post). In addition to this element, it consists of a sheath of conductive material inside and a cable that connects to the electronic system in question.<\/p>

Once you have a better understanding of how temperature control is carried out through these systems, it's time to look at the types of temperature sensors that exist today.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Depending on their operation and the way in which they transform the signal, there are different types of temperature sensors. Mainly, they are three categories: RTD sensors (PT100, PT1000, Thermistors) thermocouples and infrared<\/a>

Now we will see in detail these types of temperature sensors, in which it is possible to find different variants:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The thermocouple is the most widely used sensor.<\/strong> in temperature measurement systems. These economic sensors, easy to install and with a precision adjusted to different processes. Although its operation is sufficient, its response can be somewhat slow compared to other types of temperature sensors.<\/p>

The operation of thermocouples is based on two metallic threads of different materials<\/strong> joined at one end, which is known as a hot junction or measurement junction. It has another separate end, called a cold joint. The temperature difference between the two joints produces a voltage differential, which will be the signal sent to the electronic device.<\/strong><\/p>

Within these sensors, there are different types of thermocouples depending on the materials they are made of. The most common<\/strong> are the following:<\/p>
