In differential pressure measurement, what type of readings can sensors provide?

Differential pressure sensors are designed to measure the difference in pressure between two points, and they can provide readings that reflect both static and dynamic conditions in a system. Static readings represent the steady-state pressure differences at a given moment, while dynamic readings can capture changes in pressure over time due to fluctuations in the process, such as flow variations or sudden pressure changes.

This dual capability is vital in many industrial applications, where monitoring both stable and transient conditions is necessary to ensure safe and efficient operation. For instance, in a flow measurement context, the differential pressure across an orifice plate can indicate both the average flow rate (static) and fluctuations in flow dynamics (dynamic).

Other options do not account for the full range of functionalities of differential pressure sensors. Static readings alone would neglect the sensor's ability to track changes in pressure over time, and visual readings or readings based solely on external conditions do not accurately define the primary role of differential pressure sensors in process control.
