Semiconductor Material Heater Temperature Sensor NTC Thermistor Double Probe

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.
