What is hot electric puppet temperature sensor ？
Thermocouple is a sensor used to measure temperature. Thermocouple temperature sensor consists of two metal wire brackets made of different metals. The bracket of the wire is welded together at one end to form a connection point. This knot is where the temperature measuring temperature. When the temperature of the knot changes, voltage generates. Then you can explain the voltage by calculating the temperature.
Different types of thermocouples have many types of thermocouples. Each thermocouple temperature sensor has different characteristics in temperature range, durability, vibration resistance, chemical resistance and application compatibility. Type, T -type "Agent Metal" thermocouple temperature sensor, the most common thermocouple type. Type and S thermocouple are "rare metal" thermocouple, used for high temperature applications
Where can I use the thermocouple temperature sensor? The thermocouple is applied in many industries, sciences, and applications. They can find almost all industrial markets: power generation, mining, petroleum/natural gas, pharmaceutical, biotechnology, cement, paper, glass, and so on. Thermocouple is also used for daily electrical appliances, such as stoves, furnaces, kiln and Bisa ovens. Why use a thermocouple?
Select thermocouple The temperature sensor is usually due to their low cost, high temperature limit, wide temperature range and durable properties.
So when did the thermocouple temperature sensor occur?
History of the thermocouple temperature sensor
As early as 1821, German physicist Thomas John Saibak Martin explored the concept of different metals connected. He found the temperature changes and magnetic fields between the joints-this is a well-known SEEBACK effect.
There, the magnetic field was later discovered as part of the thermal current. The voltage generated by these two wires is used to measure the temperature from high to very low.
The threshold of measurement temperature depends on the type of wire material used. Although at a very low current, the thermocouple knot can generate electricity.
Scientists Michael Farad and George Om use the SeeBack effect to perform experiments to help further understand impact and temperature measurement.
According to this discovery and further research by scientists in history, the thermocouple was manufactured in the early 20th century. Since then, this technology has been developed and has achieved today's achievements. They are now used for many different equipment from food processing to pharmaceuticals.
Manufacturing of thermocouple temperature sensor
Since the discovery of temperature measurement technology, the manufacturing of this device has always been simple and effective. These two metal alloys are combined to form a knot.
part of the knot is placed on the source that needs to be measured. The second point of the knot is kept at the source of constant temperature.
The temperature range depends on the type of metal used in the thermocouple temperature sensor manufacturing. The temperature range of nickel and nickel is -50 to 1410 degrees, while the temperature range of and is 0 to 2315 degrees.
The structure of the thermocouple temperature sensor is very simple, and the manufacturer uses this pair of wire assembly thermometers. There is usually a layer of insulation tube protection layer on these wires.
Thermocouple temperature sensor manufacturer determines the combination of metal and calibration for assembly. The use of thermocouple depends on the environment. When making a specific type of thermocouple, different diameter and materials are considered factors.
In other cases, installing the thermocouple temperature sensor to the existing system can change the way of manufacturer's design equipment.
Types of thermocouple temperature sensor
A variety of thermocouple temperature sensors are used for different purposes and use a variety of metals.
Various hot -electrodes temperature sensors in popularity include:
1. The most common thermocouple temperature sensor type, which is cheap, reliable and accurate
2. In addition, it is very common, but there is a small temperature range, and there is a shorter life that is higher than the K -type
3. A stable thermocouple, for low temperature
4. Signals are stronger, higher accuracy
5. Has the same accuracy and limit as K, but a little more expensive
6. Mainly used in the pharmaceutical industry
7. It is similar to S -type in terms of performance. Because of its accuracy and stability, it is often used for lower temperature
8. The temperature range is the largest in all thermocouple temperature sensors
Different types of thermocouple temperature sensors are combined, including industrial, universal and multi -point thermocouple temperature sensors.
Industrial thermocouple temperature sensor is a popular type. The scope of the manufacturer provided these thermocouples from "ISA-M". The general thermocouple is suitable for most applications, and the cost is low. The most commonly used general -purpose thermocouple is K type.
Finally, the multi -point thermocouple temperature sensor is the most accurate temperature measurement form. They are used to correctly measure and manage the temperature. These are manufacturing E, K, J, N, and T. This is different materials.
Some thinking about the manufacturing of the thermocouple temperature sensor
The manufacturing of the temperature of the thermocouple temperature sensor depends on different temperature measurement needs. From low to high, various metals and materials are used to form a thermocouple temperature sensor suitable for any temperature maintenance.
When choosing the correct product, the key lies in the knowledge of and manufacturer's knowledge. The correct temperature of any component is essential to manufacture all the products related to the temperature.
