The selection features discussed here, though not exhaustive, are surely helpful to select the right manufacturer of pressure gauges and other related tools.
Pressure gauge accuracy ranges are defined either as a fraction of the full-scale range or as a proportion of the length. With the increase in the accuracy of the gauge, the price differs. Therefore, the application where the gauge is necessary should be decided carefully.
Gauge dials come in a range of sizes from 1.5″ to 16 ” diameters. The space limitations and accuracy requirements determine the dial size.
You also have to think about the connection size when choosing the manufacturer of pressure gauges. If you’re going to replace a gauge, you want to be aware of the existing connection size.
Environmental factors can determine performance. So, to select a pressure gauge, you must take into consideration the airborne particles, the surrounding temperature, compression, moisture, water part, and chemicals.
Process Media/Wetted Parts
Proper selection of the pressure gauge material is dependent on the process fluid to which the gauge is liable. The manufacturer of pressure gauges takes care of materials of the gauge that should be well-matched with the fluid process so that corrosion will not occur.
Apart from all these said above, there are other factors that the manufacturer of pressure gauges takes care of: connection location, pressure sensor elements, and many more.
