The Enclosed Operating Station (EOS) monitors which three aspects of the steam system?

• A. Steam temperature, steam pressure, and positions of MOVs
• B. Only steam temperature
• C. Only steam pressure and MOV positions
• D. Condensate flow and pump speed

Answer: (A)

The Enclosed Operating Station is designed to give you a quick, integrated view of the steam system by monitoring three things: steam temperature, steam pressure, and the positions of motor-operated valves. Temperature and pressure tell you whether the steam is within safe and desired operating limits, helping you spot conditions like overheating or overpressure. Knowing the valve positions ensures steam is being routed correctly and that safety or isolation valves are in the intended state, which is crucial for proper control and fault diagnosis. Condensate flow and pump speed aren’t what the EOS primarily displays, so those don’t fit the trio it’s meant to monitor.
