Accurate pressure measurement is essential in many industrial applications. Pressure gauges are devices used to measure the pressure a medium (such as water, air, natural gas, hydraulic fluids, etc.) exerts upon a system. They are used to maintain the efficiency and safe operation of processes in a variety of industries ranging from oil & gas to food processing.
There are two main kinds of pressure valves: those used to measure pressure in pneumatic systems and those used to monitor pressure in hydraulic systems. Some of the different types of pressure valves include:
PNEUMATIC PRESSURE GAUGES
- Bourdon tube pressure gauges are widely used in pneumatic systems for measuring gas pressure. Simple and reliable, Bourdon tube pressure gauges are used in applications that include air compressors, pneumatic tools, and industrial pneumatic systems. They’re also used in hydraulic applications such as hydraulic presses, pumps, and cylinders.
- Diaphragm pressure gauges use a diaphragm to measure pressure changes. Suitable for low-pressure measurements and harsh environments, diaphragm pressure gauges are used in pneumatic control systems, air filtration units, and HVAC systems.
- Digital pressure gauges are electronic gauges that provide digital readouts. They feature high precision, easy-to-read displays, and often include additional features like data logging. Digital pressure gauges are used for calibration, testing, and monitoring of pneumatic systems.
- Capsule gauges are ideal for measuring low pressures with high accuracy. Sensitive to small pressure changes, capsule gauges are often used in laboratory settings, sensitive pneumatic equipment, and environmental monitoring.
- Differential pressure gauges measure the difference in pressure between two points. Differential pressure gauges are useful for monitoring pressure drops across filters or other components. They’re used for applications that include air filters, pneumatic control systems, and flow measurement.
HYDRAULIC PRESSURE GAUGES
- Piston pressure gauges employ a piston to measure high pressures. Robust and capable of withstanding high pressure and vibration, piston pressure gauges are used in heavy machinery, hydraulic presses, and high-pressure hydraulic systems.
- Hydraulic diaphragm gauges are similar to their pneumatic counterparts but designed for higher pressures. Constructed from corrosion-resistant materials for hydraulic fluids, hydraulic diaphragm gauges are used to measure pressures in hydraulic lifts, cranes, and mobile hydraulic equipment.
- Hydraulic digital pressure gauges provide accurate digital readings of hydraulic pressure. They’re used for maintenance, testing, and monitoring of hydraulic systems.
- Sealed Pressure Gauges are designed to prevent hydraulic fluid contamination and feature sealed construction to prevent fluid ingress and egress. Sealed pressure gauges are used in food processing, pharmaceuticals, and other sensitive industries.
- Hydrostatic pressure gauges measure the pressure exerted by a fluid at rest. Often used for static pressure measurements, they are important tools for fluid level measurement in tanks and reservoirs.
- High-pressure hydraulic gauges are specifically designed for very high-pressure measurements. High-pressure hydraulic gauges are ruggedly built and often come equipped with safety features like blow-out backs. They’re used in industrial hydraulic systems, high-pressure testing, and hydraulic fracturing.
TIPS FOR FINDING THE RIGHT PRESSURE GAUGE
