Which safety device is typically found in low-pressure steam boilers to prevent low water conditions?

The low water cutoff is a crucial safety device in low-pressure steam boilers. Its primary function is to monitor the water level within the boiler and shut down the system if the water level falls below a safe threshold. This prevents the boiler from operating in a low water condition, which can lead to overheating and potential damage or catastrophic failure, such as a boiler explosion.

Since steam boilers require a certain level of water to generate steam safely, the low water cutoff is essential for preventing dangerous situations. When the water level drops too low, the device will automatically halt the operation of the boiler to ensure safety.

While pressure gauges monitor the pressure inside the boiler, high temperature limit switches control the temperature, and safety relief valves release excess pressure, none of these devices specifically address the risk associated with low water levels like the low water cutoff does.
