The application of resistors in many industry scenarios promotes the temperature detection function of many devices. The glass encapsulated NTC thermistor is a kind of thermistor. Its core temperature increases with the increase of the operating temperature range and has a large and predictable decrease. With the advancement of technology, the functions of glass encapsulated NTC thermistors are becoming increasingly diversified, meeting different needs, and providing important equipment for people to detect temperature.
What are the advantages of glass encapsulated NTC thermistors compared to other thermistors?
What role does the heat capacity of the glass encapsulated NTC thermistor play?
What is the standard application of glass encapsulated NTC thermistor?
Compared with RTDs, glass encapsulated NTC thermistors have the advantages of small size, fast response, strong shock and vibration resistance, and low price. Its accuracy is slightly lower than RTD.
The accuracy of these two methods is similar to the thermocouple ratio; however, thermocouples can withstand extremely high temperatures (approximately 600°C) and are used in this application. However, NTC thermistors have higher sensitivity, stability, and accuracy than thermocouples at low temperatures, and they use fewer circuits, so the total cost is lower. Because glass encapsulated NTC thermistors do not require RTD signal conditioning circuits (amplifiers, level converters, etc.), the cost will be further reduced.
The heat capacity represents the heat required to increase the temperature of the thermistor by 1°C, usually expressed in mJ/°C. When an NTC thermistor is used as a surge current limiter, it is very important to accurately grasp the heat capacity, because it determines the response speed of the glass encapsulated NTC thermistor.
They are glass encapsulated NTC thermistors sealed in glass bulbs. This material is designed to be sturdy and durable when used in an environment above 150°C or used for printed circuit board mounting. Encapsulating the thermistor in glass NTC improves the stability of the sensor and makes it immune to environmental influences. This kind of film is packaged in a glass container with a small ball NTC resistor. The diameter range of the standard size is 0.4-10 mm.
Glass encapsulated NTC thermistors are widely used. They are used to measure temperature, temperature, and temperature compensation. It can also be used to detect the absence or presence of liquids, such as current limiters in power circuits, and temperature monitoring in automotive applications. Glass encapsulated NTC thermistors can be divided into three categories according to their electrical characteristics used in the application.
1. Resistance temperature characteristics.
Its applications mainly include temperature measurement, control, and compensation. This also includes the use of glass encapsulated NTC thermistors, so that the temperature of the glass encapsulated NTC thermistor is related to other physical phenomena. This application requires the thermistor to work in a zero-power state, that is to say, through its current to make it as low as possible, thereby avoiding heating of the probe.
Technology is driving progress in the field of machine research and development, and the types of resistors are also increasing. The glass encapsulated NTC thermistor can monitor temperature changes and control the temperature within a reasonable range.
