A pressure gauge is an important device used for measuring the pressure of the force applied, be it liquid or gaseous, on the surface. It is also one of the most used devices in industrial plants and factories. Pressure gauges are very important in a production unit. These helps to detect any leakages in the unit and indicate the air flows which help in the overall functioning of the unit. It is important to note that if a pressure gauge is faulty, the entire safety and reliability of a unit will be compromised. Different pressure gauges such as Low Pressure Gauge , air pressure gauge, water test gauge and many such types are used in industrial plants. The main metals used in production of pressure gauges are brass and stainless steel. For instance, the inner system of a Low Pressure Gauge is made up of a capsule which is either stainless steel or brass depending on the type required by the plant.
