Heater Temperature Sensor NTC Thermistor
Product Description:
An NTC (Negative Temperature Coefficient) thermistor is a type of
temperature sensor commonly used in various applications, including
heaters. The term "NTC" indicates that the resistance of the
thermistor decreases as its temperature increases.
Resistance Variation: The NTC thermistor is made of a semiconductor
material whose electrical resistance decreases as the temperature
increases. The relationship between resistance and temperature is
nonlinear, and it follows a negative temperature coefficient.
Temperature Sensing: The NTC thermistor is embedded or attached to
a location within the heater where temperature monitoring is
necessary. As the heater operates, the temperature at this location
changes.
Monitoring Circuit: The NTC thermistor is part of a monitoring
circuit that measures its resistance. This circuit is typically
connected to a controller or microprocessor that interprets the
resistance value and correlates it with the corresponding
temperature.
Control System: The controller or microprocessor can use the
temperature information from the NTC thermistor to regulate the
heater's operation. For example, it may adjust the power supplied
to the heating element based on the temperature feedback to
maintain a desired temperature setpoint.
Protection: NTC thermistors are also used for protection purposes.
If the temperature exceeds a certain threshold, the thermistor's
resistance drops significantly, indicating a potential overheating
condition. This information can trigger safety mechanisms to shut
down or modify the heater's operation to prevent damage.
