Alarm operation When water temperature reaches the alarm temperature and the alarm switch is closed, the alarm light turns on. When the temperature decreases and the alarm switch is opened, the alarm light turns off. Specifications and performance Working range: 0120 degrees Alarm temperature: 97 +/ 2 degrees Response time: Approximately 1 second after the alarm temperature is reached Temperatureresistance relationship: Higher water temperature yields lower resistance; lower water temperature yields higher resistance Function and compatibility Provides a clear visual alarm indication for an overheating condition Designed to be integrated with an alarm switch; switch state controls the alarm light Physical attributes Size and material: Not specified in the available specifications Use scenarios Overheat protection in industrial heating tanks or reactors where maintaining temperature below the alarm setpoint is critical Pasteurization or sterilization processes to trigger an alarm at the end of the heating phase and prevent overheating Laboratory water baths or test rigs requiring a fast visual alert and rapid response to reaching the alarm temperature Notes All details reflect the provided specifications and functions without additional modifications or assumptions The description preserves the original brand specifications and operating behavior for reliability and consistency
