What is a common use of thermistors within boiler systems?

Thermistors are widely used in boiler systems primarily for monitoring temperature levels due to their ability to change resistance with temperature fluctuations. This characteristic makes them highly sensitive, allowing for accurate and precise temperature readings. In the context of boiler operations, maintaining the correct temperature is crucial for efficiency and safety. Thermistors can help ensure that temperatures remain within specified limits, thereby facilitating effective control over the boiler's operation and preventing overheating or other potential issues.

While pressure measurement, fuel flow control, and water purity gauging are important aspects of boiler system management, they typically rely on different types of sensors or devices that specialize in those specific functions. For example, pressure sensors are generally used for monitoring pressure levels, flow meters for controlling fuel flow, and chemical testing devices for gauging water purity. In contrast, the unique properties of thermistors make them particularly suited for temperature monitoring, which underscores their common use in boiler systems.
