Psi meaning preassure8/30/2023 The pressure-sensitive element deforms under the pressure of the gas or liquid, and this deformation is converted into a readable measurement by the measuring mechanism.įigure 3: Pressure gauge symbol How do analog pressure gauges work Pressure gauges typically consist of a pressure-sensitive element (like a bourdon tube or diaphragm) connected to a measuring mechanism and display such as a dial or digital readout. A hydraulic system is designed to work in a set pressure range, so it is crucial to ensure that the pressure gauge is rated for the operating range. Monitoring the pressure value of a hydraulic system keeps a check on the building pressure within the system. It typically consists of a dial or digital display that indicates the pressure, along with a sensor that measures the pressure and converts it into an electrical signal that can be read by the display. Read our article on pressure forms for more details on each type.įigure 2: Static pressure vs total pressure Static pressure (A& B), dynamic pressure (C), and total/stagnation pressure (D & E) What is a pressure gauge?Ī pressure gauge is a device that measures the pressure (intensity) of a fluid. Pressure is often measured in three forms: absolute, gauge, and differential pressure. The Instruments discussed in the following sections are designed to measure the static pressure in a system. ![]() The total pressure of a flow (also called stagnation pressure) is the sum of static and dynamic pressure in that flow (Figure 2 labeled D).Īn instrument measures the total pressure of the flow if it faces the flow direction. This extra pressure is called dynamic pressure (Figure 2 labeled C). However, a moving fluid applies additional pressure in the flow direction while having a negligible impact on the surfaces parallel to the flow direction, as seen in Figure 2. ![]() Static pressure (Figure 2 labeled A) is uniform in all directions. ![]() In a stagnant liquid or gas, this is the force applied to the wall of the container at a given point. Pressure is the amount of force applied perpendicular to a surface per unit area. View our online selection of pressure gauges!īasics of pressure & pressure measurement
