Using Thermistors to Create Temperature Alarms
Jul 12, 2024Temperature is a critical physical parameter, and its measurement and control hold significant importance across various domains. With advancements in modern industrial and agricultural technologies and the increasing demand for comfortable living environments, there is a pressing need for effective temperature detection and control mechanisms. One prominent application in this context is the temperature alarm, where NTC thermistors play an essential role.
A standard temperature alarm system comprises two main components: the temperature control unit and the alarm. These systems are highly operable and widely applicable, typically measuring temperatures within a range of 20°C to 100°C. When the monitored temperature reaches a preset threshold, the characteristics of the NTC thermistor allow it to collect a voltage signal. This signal then triggers the alarm, immediately alerting to potential issues and preventing unnecessary losses due to temperature fluctuations.
The fundamental principle behind using NTC thermistors for temperature measurement lies in their resistance-temperature relationship, which closely follows an exponential function. This relationship enables the creation of a resistance-temperature characteristic curve, where each temperature corresponds to a specific resistance value. By measuring the resistance, the corresponding temperature can be accurately determined, forming the basis for NTC thermistor-based temperature measurement.
