V Thermistor application example Of The Epoxy Resin NTC Thermistor 100K 4200

Thermistors serve a crucial role in temperature detection. For example, thermistor temperature detection

can be used in fire alarms to detect fires based on a sudden change in temperature. Unlike photoelectric

detectors or ionization alarms, thermistors only require heat to activate.

VI Thermistor Temperature Detection in Fire Alarms

The thermistor method, unlike the previous examples, uses heat detection to activate. The alarm activates

once the thermistor detects a high temperature. Thermistor temperature detection doesn’t require smoke

to activate and has fewer false alarms. The thermistor uses the ambient temperature of a building and

will only activate when that temperature increases exponentially. The thermistor method is reliable in this

fire alarm example as there would be few false alarms and a quicker alert rate, but the thermistor method

is also versatile.
