Understanding Piston Differential Pressure Gauges

In industrial applications, precision measurement of pressure differences is essential for ensuring optimal performance and safety of various processes. One of the key instruments used for this purpose is the piston differential pressure gauge. This gauge is designed to measure the pressure difference between two points within a system, providing critical data for monitoring and controlling operations.

What is a Piston Differential Pressure Gauge?

A piston differential pressure gauge operates on the principle of balancing two pressures using a movable piston. The gauge consists of a cylinder and a piston that separates two chambers. Each chamber is connected to different pressure points within a system. When a pressure difference exists, the piston moves in response to the force exerted by the higher pressure side compared to the lower pressure side. The displacement of the piston is then converted into a readable measurement, typically displayed in units such as psi, bar, or kPa.
