Choosing the Right Pressure Gauge: What to Consider
Choosing the right pressure gauge can cause some confusion, particularly with so many options on the market. To put you on the right track, here are the most relevant considerations for determining the right pressure gauge for your application:
It is ideal to select a pressure gauge that is approximately twice the normal operating pressure of the media. Furthermore, the maximum operating pressure should not exceed 75% of the full-scale range.
The size of the pressure gauge will usually correlate with the gauge's accuracy.Larger pressure gauges will generally have greater resolution or readability.
The material of the pressure gauge is important when considering the environment in which it is going to be used. Assess if the gauge is going to be subject to higher levels of moisture or more severe weather conditions. Stainless steel pressure gauges should be opted for over brass around more corrosive substances.
Accuracy is defined as a percentage of the full-scale range. For example, 63mm gauges will generally have 1.6% full-scale accuracy (FSA), likewise for 100mm and 160mm gauges where they will generally have 1% FSA. The degree of accuracy required should be determined to ensure that a suitable gauge is used. Choosing between an analogue ordigital pressure gauges is also another factor to be considered as they have different degrees of accuracy. A general rule of thumb is that the more critical the application, the higher the accuracy required.
Along with theconnection size, the location should also be considered when selecting a pressure gauge. GTS stock a range of rear-entry and bottom-entry gauges to meet your application needs.
