MgO Temperature Sensor: Principle, Application, and Development Prospects

In modern technology applications, temperature sensor plays the role in various fields. This article will introduce the importance of a common and important temperature sensor – magnesium oxide temperature sensor. We will discuss its work principles, application and prospect.

Working principle

Magnesium oxide temperature sensor is based on the thermoconductive properties of magnesium oxide. When the temperature changes, the conductivity of magnesium oxide will also change. The sensor contains a thin magnesium oxide resistance wire. When the temperature rises, the resistance value of the magnesium oxide resistance wire decreases; and when the temperature decreases, the resistance value increases. With this characteristic, the temperature change can be measured indirectly by measuring the resistance change of the magnesium oxide resistance wire.

Application

Industrial automation: MgO temperature sensor iswidely used in industrial automation to monitor and control the temperature of various industrial processes. For example, in industries such as chemical industry, electric power, and steel, temperature sensors can be used to monitor temperature changes in reactors, boilers, furnaces, and pipelines to ensure safe operation and improve production efficiency.
Environmental monitoring: Magnesium oxide temperature sensor can also be used in the field of environmental monitoring. For example, in atmospheric science research, measuring temperature changes in the atmosphere is critical to understanding climate change and weather forecasting. Magnesium oxide temperature sensor can be used in conjunction with other sensors to provide accurate weather data.
Medical applications: Temperature sensors also play an important rolein medical equipment. Magnesium oxide temperature sensor can be used to monitor body temperature and iswidely used in thermometers, medical imaging equipment, and laboratory instruments.

Development Prospect

The application of magnesium oxide temperature sensor in modern technology is constantly expanding and has shown development prospects in the following areas:

Application in high temperature environment: Magnesium oxide temperature sensor has good high temperature stability and corrosion resistance, which enables it to work stably in high temperature environment. With the increasing demand for high temperature monitoring in the industrial field, the application of magnesium oxide temperature sensors in high temperature conditions will be further expanded.
Accuracy and sensitivity improvement: With the continuous improvement of the process and the development of technology, the accuracy and sensitivity of the magnesium oxide temperature sensor will be further improved. This will make it more useful in more sophisticated applications, such as aerospace and scientific research.
Diversified packaging and integration: Integrating the magnesium oxide temperature sensor with other sensors and chips can realize multi-functional monitoring and intelligent control. Combining it with wireless communication technology can realize wireless monitoring and remote data transmission, further expanding the application field and convenience.

Magnesium oxide temperature sensor, as an important temperature measurement tool, has a wide range of application fields and development prospects. With the continuous advancement of science and technology, magnesium oxide temperature sensor will continue to develop in high-temperature environments, accuracy and sensitivity improvements, and diversified packaging and integration, providing more accurate, reliable and intelligent temperature monitoring solutions for all walks of life.

Thermal Conductive Filler Alumina Powder

Commonly used thermal conductive materials are:  auminum oxide nanopowder, zinc oxide nanopowder, magnesium oxide nanopowder, aluminum nitride, boron nitride, silicon carbide and so on.

Alumina Al2O3 has the advantages of thermal conductivity and insulation, and can be used as a thermally conductive filler to prepare thermally conductive insulating glue, potting glue and other polymer materials. Compared with other fillers, although the thermal conductivity of alumina is not the best, it can basically meet the basic thermal conductivity requirements. In addition, the price of alumina is relatively low, and the source is relatively wide. It is an economical and suitable filler for high thermal conductivity insulating polymers.

Hongwu Nano can produce white alumina micron powder in batches, with narrow particle size distribution, stable process and high thermal conductivity. According to customer feedback, the thermal conductivity can reach between 3-10W/(m*K) according to different filling amounts.

The particle size of alumina powder used for thermally conductive fillers is 1um, 500nm, 300nm, 200nm. The bulk price is more cost-effective.

Thermally conductive alumina can be widely used in different materials such as silica gel, potting glue, epoxy resin, plastic, rubber thermal conductivity, thermal conductive plastic, silicone grease, heat dissipation ceramics, etc. In practical applications, Al2O3 powder filler can be used alone or mixed with other fillers such as AIN and BN.

In order to improve the dispersibility of the alumina powder, the surface of the alumina can be modified with a silane coupling agent or hexadecyltrimethoxysilane.
