How to Choose the Best Pressure & Vacuum Gauges
Gauge Type
Consider whether you need a pressure gauge, a vacuum gauge, or a compound gauge that measures both. Pressure gauges are used for positive pressures, while vacuum gauges measure negative pressures (below atmospheric). Compound gauges offer versatility for systems that operate in both ranges.
Range and Accuracy
Determine the expected operating pressure or vacuum range for your application. Gauges are rated for specific ranges, and choosing one with a range slightly above your maximum expected value is advisable for longevity and accuracy. Also, consider the required accuracy level. Higher accuracy may be necessary for sensitive processes.
Connection Type and Size
Ensure the gauge's connection type and size are compatible with your existing system or fittings. Common connection types include NPT (National Pipe Thread), BSP (British Standard Pipe), and flange connections. The size of the connection (e.g., 1/4", 1/2") is also critical for a proper seal and secure installation.
