What is an NTC temperature sensor?
An NTC thermistor is a temperature sensor that uses the resistance properties of ceramic/metal composites to measure the temperature. Our full spectrum NTC sensors offer many advantages in temperature sensing including miniature size, excellent long-term stability, high accuracy and precision.
What does NTC stand for in NTC thermistor?
Negative Temperature Coefficient
When we are discussing NTCs we are referring to a type of temperature sensor; an NTC thermistor. In this instance, NTC defines as “Negative Temperature Coefficient”. Thermistors measure temperature by measuring the resistance of the electrical energy passing through the thermistor which is relative to temperature.
What are the types of thermistor?
The main two types of thermistors are NTC (Negative Temperature Coefficient) and PTC (Positive temperature coefficient). Thermistors measure temperature by using resistance. With an NTC thermistor, as the temperature increases the resistance decreases, and when the temperature decreases, the resistance increases.
How do I know if a thermistor is bad?
The most common way to know if a thermistor is bad if it starts displaying inaccurate temperature readings. This can be caused by excessive heat, improper handling, a thermal mismatch, or a dip in resistance accuracy due to regular use and age. An open circuit can also lead to thermistor issues.
How does NTC sensor work?
With an NTC thermistor, when the temperature increases, resistance decreases. Conversely, when temperature decreases, resistance increases. When temperature increases, the resistance increases, and when temperature decreases, resistance decreases. This type of thermistor is generally used as a fuse.
What is NTC full form?
NTC full form is Negative Temperature Coefficient. In general conductive material have positive temperature coefficient. Resistance increase with the increases of temperature.
Where are NTC thermistors used?
Thermistor probes can be used in automobile and truck tire curing, as well as for monitoring and controlling engine temperatures. They are even used in missiles and spacecraft. Some more potential equipment uses of NTC thermistor probes are for plastic laminating and hot glue, as well as fire protection and safety.
