Which device is used to monitor process pressure?

• A. Pressure sensor
• B. Temperature indicator
• C. BPCS
• D. CRW

Answer: (A)

Monitoring process pressure requires a device that directly senses pressure and converts it into a usable signal for readings or control. A pressure sensor does exactly that: it detects the actual pressure in a vessel or line and outputs an electrical signal that can be read by displays or fed into a control system for monitoring and safety actions. The temperature indicator, by contrast, measures temperature, not pressure. The Basic Process Control System is the overall system that processes sensor signals and controls equipment, not a single device that directly measures pressure. CRW isn’t a standard pressure-monitoring device in typical process safety contexts. So, the pressure sensor is the correct choice because it provides the actual pressure measurement needed to monitor the process.
