glass encapsulated NTC thermistors are used in industrial, medical, environmental protection, meteorological, food processing equipment, and other fields. With the advancement of technology, various types of glass encapsulated NTC thermistors have been produced to meet the work needs of different industries and different scenarios, greatly improving product quality and work efficiency, and becoming an indispensable part of people's production and life.
What is the lifespan of the glass encapsulated NTC thermistor?
What is the glass encapsulated NTC thermistor temperature range?
What is the history of glass encapsulated NTC thermistors?
"Long-life glass encapsulated NTC thermistor" is an improvement in the understanding of glass encapsulated NTC thermistors, emphasizing the importance of resistance life. The most important thing for a glass encapsulated NTC thermistor is its life. After it can withstand various high-precision, high-sensitivity, high-reliability, ultra-high temperature, and high-pressure tests, it still works stably for a long time.
Life is an important performance of glass encapsulated NTC thermistors, which has a dialectical relationship with other parameters such as accuracy and sensitivity. A glass encapsulated NTC thermistor product must first have a long life to ensure the performance of other properties; and the excellent performance of other properties depends on the production process to reach a certain technical level, which makes the long life of the NTC possible.
Many high-tech electronic products require thermistors to perform stable temperature control and temperature measurement functions under ultra-high temperature, ultra-high pressure, and other harsh conditions. Most manufacturers blindly pursue the accuracy, sensitivity, and drift value of glass encapsulated NTC thermistors. The stable performance of conventional performance neglects the life of the resistor, which affects the use of electronic products because the NTC cannot work for a long time. As a result, all the accuracy, sensitivity, high-temperature resistance, etc., become meaningless.
Its measuring range is generally -10～+300℃, it can also be -200～+10℃, and it can even be used for temperature measurement in the environment of +300～+1200℃.
The accuracy of the negative temperature coefficient thermistor thermometer can reach 0.1℃, and the temperature sensing time can be as short as 10s or less. It is not only suitable for granary thermometers, but also temperature measurement in food storage, medicine and health, scientific farming, oceans, deep wells, high altitudes, and glaciers.
The development of glass encapsulated NTC thermistors has gone through a long stage. In 1834, scientists discovered for the first time that silver sulfide has a negative temperature coefficient. In 1930, scientists discovered that cuprous oxide-copper oxide also has the performance of a negative temperature coefficient, and successfully used it in the temperature compensation circuit of aeronautical instruments. Subsequently, due to the continuous development of transistor technology, thermistor research has made significant progress. NTC thermistor was developed in 1960. Later, with the advancement of technology, a glass encapsulated NTC thermistor was developed.
