One of the most important quantities measured in industrial units is the quantity of pressure. To determine the type of instrumentation equipment, one of the items that is always questioned is the pressure of the system and therefore the maximum tolerable pressure. This quantity Due to the fact that in some cases, such as altimetry, fluid level and also fluid flow rate measurement is also important, and various equipment and tools have been devised to measure it in different conditions.
The pressure sensor generally measures the gas or liquid pressure. The so-called pressure is the force necessary to prevent the fluid from spreading and is usually defined as force on the surface. The pressure sensor usually acts as a converter, and the signal produces a function of the pressure effect. An electrical signal can be considered for this purpose. Daily pressure sensors are used to control and monitor thousands of applications.
Therefore, we always need equipment in order to declare the pressure of the system in accordance with the environmental conditions and standards, and act accordingly. A pressure gauge that uses a mechanical bourdon tube or a diaphragm mechanism, and in some cases an element pulley, by changing the state of the pressure element on the measuring element and transferring this state change to a one-handed, calibrated by pressure on a plate. The simplicity measures the pressure values in a wide range even up to 1000 times.

Types of pressure gauges
Negative pressure gauge
Vacuum pressure gauge
Diaphragm pressure gauge
Oxygen pressure gauge
Digital pressure gauge
Test pressure gauge
Oil pressure gauge
Differential pressure gauge
The state when the gauge is exposed to air (atmospheric pressure) does not show a zero number:
In this case, the gauge can be set to indicate a zero number for the atmosphere.
The other way is to record the number of barometers when in atmospheric pressure, for example, the number 5-. The final vacuum is obtained when the gauge falls below the actual number of atmospheric pressure.
In selecting the appropriate analog barometer, the following should be noted:
– The desired pressure gauge
– Blood Pressure Gauge Screen
– Type and size of pressure gauge thread
– Pressure gauge
The pressure gauge is usually a steel or brass manometer
– Adjustable or vertical (connection from below or from the back) in the pressure gauge installation
