Pressure gauge A pressure gauge is a device that helps monitor the pressure in a system. Water systems and tanks work on the pressure of water and air inside. A pressure gauge measures the pressure force in the water or air so you can determine if you have any faults in your tank or system. If the pressure inside the system is significantly different from the norm, you must take action to correct the fault in the system.
Pressure measurement, along with temperature measurement, is one of the most critical measurements for operations in many different applications – especially industrial applications – and it is essential to ensure both product quality and the safety of facilities and employees.
Pressure gauges are used to monitor and control pressure – this is often essential in industrial processing. Without pressure gauges, industrial processing systems would be unpredictable and unreliable.
Pressure gauges are used by industry professionals to troubleshoot fluid power equipment – they are designed to operate within a set pressure range. With a properly installed gauge, leaks and unwanted pressure changes can be monitored and resolved immediately.
In the United States, the most commonly used units for measuring pressure are pounds per square inch (psi), bar, and millibar (mbar). The international standard unit for pressure is the pascal (abbreviated Pa): N/m 2 , or newtons per square meter. 1 bar = 100,000 Pa. Pressure can also be measured in atmospheres (atm), inches of mercury (in. Hg), millimeters of mercury (mm Hg), and torr (about 133.3 Pa). The unit used depends on the pressure measuring instrument, the industry, and the country's preferences and measurement standards. As in Japan and other Asian countries, Mpa,,,, is commonly used.

To understand which pressure gauge to use for a particular application, one must understand the different types of pressure.
All pressures are measured relative to a reference pressure. The difference in pressure types is what the reference pressure is defined as.
Pressure gauge – psig Pressure is measured relative to the local ambient pressure. This type of pressure is not referenced to the surrounding air (or atmospheric) pressure – meaning that the pressure measured includes the pressure from the weight of the atmosphere. Therefore, the pressure measured varies with altitude above sea level as well as weather conditions.
Absolute pressure Absolute pressure is pressure relative to a perfect vacuum.
Pressure difference – psid Differential pressure is a measurement of pressure between two pressure points. While all pressures are essentially differences – gauge pressure relative to atmospheric pressure and absolute pressure relative to a vacuum – differential pressure measures pressure where the reading and reference values can vary.
Pressure Mixture Gauge Pressure Mixture measures both positive and negative pressure (vacuum).

Digital pressure gauge
Digital pressure gauges are becoming increasingly popular, providing quick results with clear readings and very high accuracy. These sensors are much more durable than analog sensors and are capable of operating in harsh conditions with heavy mechanical vibration. Additionally, digital pressure gauges are calibrated for longer periods of time and are much more accurate than analog sensors.
Another big advantage of digital pressure gauges is the data they are capable of providing. What types of High precision pressure gauge This can send results to computers, data loggers, and other instruments for analysis. Digital pressure gauges are ideal for very low pressures or small incremental pressure changes that cannot be detected with analog gauges.
Digital pressure gauges also offer more control – units can often be changed, min and max data can be recorded, backlighting can be added, and some DPGs even have alarms.
