Dial Indicating Absolute Pressure Gage

A Dial Indicating Absolute Pressure Gauge is a type of pressure measuring instrument used to measure the absolute pressure of a fluid or gas. It consists of a dial face with a pointer that moves in response to changes in pressure. The dial is marked with units of pressure, typically in pounds per square inch (psi) or pascals (Pa).

The gauge is connected to the system or container being measured through a pressure port. As the pressure in the system changes, it is transmitted to the gauge, causing the pointer to move and indicate the corresponding pressure reading on the dial.

Unlike a differential pressure gauge, which measures the difference between two pressures, an absolute pressure gauge measures the pressure relative to a perfect vacuum. This means that it takes into account the atmospheric pressure in addition to the pressure of the fluid or gas being measured.

Dial Indicating Absolute Pressure Gauges are commonly used in various industries, including manufacturing, oil and gas, HVAC, and automotive, to monitor and control pressure in systems and processes. They are available in different sizes, pressure ranges, and accuracy levels to suit different applications.
