In the demanding environment of oil and gas operations, precise monitoring of pressure is critical for safety, efficiency, and production optimization. Pressure indicators play a vital role in providing real-time insights into the internal pressure of pipes, vessels, and various equipment.
What is a Pressure Indicator?
A pressure indicator, often referred to as a pressure gauge, is a dial instrument designed to visually display the pressure within a closed system, such as a pipe, vessel, or tank. It works by converting the pressure exerted on a sensing element into a measurable displacement, which then moves a pointer across a calibrated dial.
How Does it Work?
The core of a pressure indicator is its sensing element. Common types include:
The sensing element's displacement is amplified and transmitted to the pointer, which moves across the dial, indicating the pressure value in a specific unit (e.g., psi, bar, kPa).
