NTC thermistor (II)

II. The performance of thermistor

With higher and higher precision requirement for temperature measurement and more and more harsh measurement environment requirement, high stability and precisionthermistor has been developed and produced. This kind of thermistor has compact size, wide resistance, high precision, and short response time.

III. The development of thermistor

As the thermistor in high temperature application, it shall has the following conditions:

a. Thermistor material is stable; electrode material is stable, with high density, and is connected closely with the lead.

b. Thermal expansivity of the thermistor, the lead and packaging materials match.

c. The lead and packaging material are stable.

d. The packaging material has good insulativity in high temperature.

e. Heat and shock resistance, and reliability.

High precision high stability NTC thermistor is mainly applied for temperature control and measurement for xerographic printer, automation equipment, thermal printing heads, furnace and water heater. In recent years, NTC thermistor has been used in automobile in a new way. It’s used in electronic oil injection system of automobile motor for measuring the temperature of the exhaust gas in order to improve fuel utilization.
