Types of Pressure Gauges
Pressure gauges provide a variety of benefits in many different industries. Without pressure gauges, it would be impossible to determine the pressure in an object or container. Pressure readings are necessary to ensure the safety of containers, employees, and the materials inside the pressurized containers. Pressure gauges are used with everything from tire pressure to the pressure of containers of steam used for boilers and much more. Each kind of pressure gauge has its own method of measurement.
Air pressure: Air pressure gauges work by measuring the ideal amount of gas that a container requires to maintain ideal pressure. Usually, this is used for tires and other inflatable products to prevent them from going flat or exploding.
Oil/hydraulic pressure gauges: Hydraulic pressure gauges use hydraulic fluid or oil to lubricate the parts of a machine to prevent excessive friction that can damage the machine. The gauge identifies whether there is enough fluid to lubricate the object properly.
Differential pressure: A differential pressure gauge can show the variation in pressure between two containers by the fluid inside of a “U” shaped tube. This system has two entrance ports with either port connected to a separate container for easy pressure comparison.
Digital pressure: Digital pressure gauges convert pressure readings into a digital display. This makes it easier to read accurate pressure readings where accuracy is extremely important.
Diaphragm pressure: This pressure gauge works like a human diaphragm to measure the pressure in a container. A capsule is divided with a diaphragm. One side measures the target pressure rating and the other monitors the actual pressure rating.
