Many combinations of materials have been used to produce acceptable thermocouples, each with its own application. The sensors are designed to correspond to a temperature relationship of e.m.f / specified in tabulated values.

Purchasing a thermocouple sensor or thermometer requires a careful examination of these products, which can not be done easily without consulting and guidance with experts.

e.m.fs is normally dissolved at 1 mV against temperature at intervals of 1 ° C and vice versa. Internationally, these tables are reference.

Buy industrial thermocouples

In the following, we will examine the types of thermocouples and briefly explain each of them:

It is necessary to pay attention to the fact that different types of thermal pairs have different temperature ranges and you, dear ones, should not buy temperature sensors that are not suitable for your needs. Mistakes in buying a variety of temperature sensors will cause you irreparable problems.

Wired thermocouple

Wired thermocouple is one of the most widely used thermal sensors. It is better to use the term cable for this new pair of heat. The important question is whether the thermocouple cable used in it is of lengthening or compensating type?

In most reference scientific texts, it is emphasized that Thermocouple Extension Cables should be used to make a wired thermal pair. For example, we have three types of cables for the K-type heat meter. KX, KCA and WX type cables. The WX task is obvious, because due to its lower purity, the maximum temperature of the thermocouple should be 800 degrees Celsius. Also, cable cuts for 1x2x0.50 mm square size should be less than 15 meters and even less.

Buy wired thermocouple

PVC coated KCA interface cable is actually one of the most widely used thermal coupling interface cables for long distances. But the best type of cable to increase the length of the thermometer, which can be used instead of the previous two types, is the KX type. This type is more expensive than the previous types and has a higher quality grade and the purity percentage of this type has the closest analysis compared to the previous two types. I emphasize that the use of this type, which is always indicated by the abbreviation X, is necessary to make a wire thermal pair. Typically, these types of thermometers have an extraordinary lifespan and performance.

Ceramic thermocouple

Ceramic thermocouple is in the category of high temperature sensors. Ceramic protective sheath of C610 type is made according to German DIN standard. In fact, it can be said that this pod is the meeting point of industrial thermometers based on metal (Base Metal) and based on noble metals (Nobel Metal).

Ceramic thermocouple

In simpler language, we can put the internal wire of thermocouple (heat pair) type K, which we want to put the temperature according to international standards up to 1260 degrees Celsius inside the ceramic protective sheath. We can also make thermal type S type If we want to measure the temperature up to 1400 degrees Celsius, use the KER 610 ceramic sheath. This ceramic sheath has a fragile structure and fluid contact and objects should be avoided.

Types of Thermocouple sensors in terms of structure

Many combinations of materials have been used to produce acceptable thermocouples, each with its own application
Spectrum However, the value of interchangeability and the economics of mass production have led to standardization. Certain types are now readily available and cover most temperature and ambient applications.

These thermocouples are designed to match a temperature relationship of e.m.f / specified in tabulated values.

e.m.fs is normally dissolved at 1 mV against temperature at intervals of 1 ° C and vice versa. Internationally, these tables are reference.

However, the standards do not take into account the construction or insulation of the cables themselves or other performance measures. With the variety that can be found, the standards of the manufacturers themselves must be trusted in this regard. At this point, it’s worthwhile to look at each one in turn, evaluating its value, properties, and application development. notice that
The positive element is always mentioned first. Also note that, especially for base metal thermocouples, the specified maximum operating temperature is not all.

Types of thermocouples in terms of typing

Now we are going to examine the sensors or thermometers of thermocouples in terms of type, type or type:

K-type thermocouple

Buy K-type thermocouples

Type K thermocouple can be called the most widely used thermocouple in the industry. Low cost and relatively good measurement accuracy are the features of this type of thermocouple sensor. This thermal pair can be used with a variety of series to connect at the desired location. For example, models of the Taiwanese series (Bolt), English series or M8 screw and Scotch design are more used.

Type J sensor
Buy J type thermocouple sensor

Type J thermocouples can be called the most widely used thermal pair after type K. One of the reasons for this is the accessories of heat meters. Because in many cases it has been seen that the peripheral device is available as a single range with J or K type input. This is seen in a variety of thermostats, temperature transmitters as well as heat coupling interface cables. Of course, it is gratifying that this trend is improving in recent years.

The proposed solution for transmitters and thermostats is that these equipments are produced and supplied as multi-range inputs and the user can use it according to his needs. A great feature of this method is that you can change the type of temperature sensor if the operator needs it, but there is no need to change the temperature transmitter and it is enough to change the settings (Configuration). This is also called calibration (footnote 2 *) of the temperature transmitter.

Heat pair T type

Type T heat coupling is one of the functional and reliable temperature sensors. In this type of thermal sensors, the positive base is made of copper and the negative base conductor is made of nickel copper. This structure is the best type of thermocouple for measuring negative temperatures and is more stable at these temperatures than other thermal pairs. Also, this type of heat pair is very resistant to corrosion and rust.

Type E sensor

The positive base conductor in this thermometer is made of Cromell and the negative base is made of Constantan. This type of thermal pairs is not recommended for use in oxidizing and neutral environments in terms of alkali and acid and has the highest effective voltage at the same temperature between the existing thermal pairs. Therefore, it is better to use it in long transmission distances to reduce the voltage and cause less error.

Thermocouple type N

In type N temperature sensor, the positive base is made of nickel chromium silicon and the negative base conductor is made of nickel silicon. This structure has a structure almost similar to type E and K thermocouples and can be used instead. Type N thermal pairs are more expensive and less sensitive than these two types. But because both bases do not have a magnetic property (they do not have Fe), it is better to use them in oxidizing environments. Also, at high temperatures, this thermocouple shows a more stable behavior than type K and E.

Type S thermocouple

In this thermal pair, the positive base is made of platinum-radium and the negative base conductor is made of platinum. The Type S heat measuring device works based on the behavior of free electrons of the noble metals platinum and radium. For this reason, this heat pair is sometimes referred to as the Platinum Radium Sensor. Of course, we can choose this name for all three types S, R and B. But to avoid common mistakes according to international standards, it is better to abbreviate these sensors.

R type sensor

The thermal pairs of type S and R are very similar and their operating temperatures are very close to each other. A common mistake that occurs in this field is to use the outer cable of type S thermocouple instead of type R thermocouple cable. .

Type B thermocouple

The positive base in type B temperature sensor is made of platinum-radium and the negative base is made of platinum. This structure is classified in the category of high temperature thermocouples, but it is also used in low temperatures due to its high accuracy in some industries. Takes. The only difference with type R, S is in the percentage of purity of the conductor of the constituent bases and it is more expensive than other thermal pairs.

Thermal coupling type C.

Thermocouple type C is one of the most special and complex types of heat measuring devices. As it must withstand temperatures above 2000 degrees Celsius. This thermal pair is one of the few thermal measuring devices that must measure and withstand a temperature of 2000 degrees Celsius! At present, the manufacture and production of Type C thermocouples is the monopoly of a handful of countries.

What is a thermocouple and how does it work?

Thermocouples are, in simple terms, electrical devices for measuring temperature that require two heterogeneous conductors to do the job. Thermal coupling performance is based on the free electrons in the inner wire. Typically, there are 10 to 28 free electrons per cubic meter of a sample metal.

Literary meaning of thermocouple:

(Thermocouple, heat coupling, temperature difference measuring device, thermal sensor)

It is a device that consists of connecting two different metal conductors, such as copper and iron, which generate an electric force when the conductors are held together.

Temperature difference force:

It is used to determine the temperature of the third material by attaching it to the joint of metals and measuring the generated electric motor force.

Thermocouples and RTDs are widely used in various industries. Reasonable price and reliability are two very important features of this instrumentation equipment. Unfortunately, in many cases, due to the complexity of other instrumentation equipment, the electrical or commercial experts of the companies may simply purchase a variety of thermal pairs! It has been seen in many cases that Thermocouple is said to have nothing! But we want to prove to you in the following text that heat meters have many things and have a complex and important structure.

The thermocouple is based on the thermoelectric phenomenon and the tuber effect. An important point that is often overlooked is the behavior of the electrons inside the heat pair. From the start of the temperature measurement until the temperature is displayed on the digital thermostat screen in the control room, the purpose of the heat meter, interface cable and digital thermostat is clear. The goal is to get the measured signal to its destination in the shortest possible time with the least voltage drop.

So in this section, you will learn how the thermocouple thermocouple works. In the following, we will review the rules and purchase different types of Thermocouple.

What are the rules of thermocouples and the effect of Seebeck?

Thomas Juan Siebek discovered the laws of thermocouples and their operation in Germany in 1821. In honor of the scientist’s efforts, this great discovery was named the work of the tuber. If we want to define the effect of tuber in one sentence, we must say that the heat pair converts thermal energy into electrical energy. In fact, Thomas had discovered that the current of heat meters in a closed circuit.

Thomas Joan Sibek found that he could expose two conductive materials with different constituents to temperature. In this case, a voltage difference occurs between the two ends of the wire. This potential difference depends on the material of the wire (due to the behavior of free electrons) and the amount of temperature applied to each material. Hence, over time, different types of industrial thermometers were discovered.

Refractory metal thermocouple

Refractory metal thermocouples are among the products produced by many thermocouple manufacturers and manufacturers in the world. These thermocouples are made of metals such as tungsten and rhenium, which are very expensive, very, very time consuming, expensive and complex, and must be used carefully. Here are three types of sensors:

Type G (tungsten / tungsten 26% rhenium)
Type D (3% rhenium tungsten / 26% rhenium tungsten)
Type C (5% rhenium tungsten / 26% rhenium tungsten)
(Note: Letters of the type mentioned are standard letters for refractory thermocouples). Refractory sensors have a temperature range of 32-4200 degrees Fahrenheit or (0 to 2315.556). Refractory metal thermocouples are commonly used in vacuum furnaces beyond the temperature capabilities of platinum.
