Pressure gauges and transmitters are essential instruments used in boiler systems to accurately measure and monitor the internal pressure of steam or water. A pressure gauge provides a direct reading of the pressure within the boiler, allowing operators to make immediate adjustments as necessary to maintain safe operating conditions.

Transmitters, on the other hand, play a critical role in continuously monitoring pressure levels, converting the pressure readings into electronic signals that can be transmitted to a control system. This allows for real-time data analysis and monitoring, helping to ensure the boiler operates within its designed pressure limits.

Using these instruments is vital for maintaining the safety and efficiency of a boiler, as improper pressure levels can lead to mechanical failures or unsafe operating conditions. Other options, such as flow meters, thermometers, calorimeters, anemometers, humidity sensors, and voltmeters, are designed for different measurements and do not provide the specific information needed to assess boiler pressure.
