What is a common application for a thermistor?

• A. To control humidity levels
• B. To measure temperature in HVAC systems
• C. To detect gas leaks
• D. To monitor airflow

Answer: (B)

A thermistor is a type of temperature sensor that is highly sensitive to temperature changes, making it particularly suitable for measuring temperature in various applications, including HVAC systems. In HVAC systems, accurate temperature readings are essential for maintaining comfort and efficiency. Thermistors can provide precise measurements due to their resistance characteristics, which change significantly with temperature fluctuations. This characteristic allows HVAC systems to adjust heating and cooling processes effectively, ensuring optimal performance and energy efficiency. While other options represent functions that are essential in building management systems—such as controlling humidity levels, detecting gas leaks, and monitoring airflow—these tasks generally rely on different types of sensors specifically designed for those applications. For example, hygrometers measure humidity, gas detectors are used for leak detection, and anemometers monitor airflow. Thermistors, with their specific design and functionality, are primarily associated with temperature measurement, especially in HVAC environments.
