Temperature sensors are essential components in HVAC systems that serve as safety devices by monitoring the temperature within the system. They play a crucial role in ensuring that the system operates within safe temperature limits. If temperatures exceed predetermined thresholds, these sensors can trigger alarms or system shutdowns to prevent overheating, which can lead to equipment damage, system failure, or even fire hazards.

In the context of HVAC systems, maintaining appropriate operating temperatures is vital for both safety and efficiency. The sensors provide real-time data that helps the HVAC system maintain optimal performance while safeguarding against risk factors associated with extreme temperature variations. This makes temperature sensors a key component for ensuring the safe operation of HVAC systems.
