A suction gauge is a crucial instrument used to measure differential pressure, specifically the difference in pressure between two points. According to the reference provided, it is fitted between the Outlet and Inlet ports within a system.
The primary function is to quantify this pressure difference, with the measurement typically expressed in Inches of Mercury (Inches of Hg or inHg). This unit is commonly used for measuring vacuum or pressure below atmospheric pressure.
Understanding the Measurement
The gauge doesn't measure absolute pressure but rather the difference in pressure between the two ports it is connected to. This differential pressure reading provides insight into the vacuum level or suction being generated within that part of the system.
Role in a System
The reference highlights the gauge's role in conjunction with other components:
- It is connected to the Outlet and Inlet ports.
- The Outlet sides of the Two Gyro's are linked to a vacuum regulator.
- This vacuum regulator is used to control the amount of airflow.
The suction gauge then measures the vacuum level resulting from this regulated airflow, effectively indicating the performance or status of the system creating the suction. The regulator adjusts the airflow, and the gauge shows the measured vacuum (differential pressure in inHg) that results from that adjustment.
In essence, the suction gauge provides a quantifiable reading of the vacuum level or suction being created and maintained between specific points in a system, allowing operators or automated systems to monitor and control it.
