A digital pressure gauge is a device that is used to measure pressure, displaying the findings in different decipherable numerical units. These pressure gauges like digital multimeters are available in many different forms as per the technology used in their operation.
Digital Pressure Gauge varieties as per technology used
Among the various digital gauges available today, there are different varieties that offers different output, as per individual consumer requirement. There are devices using mechanical deflection that includes an elastic or flexible element such as a diaphragm. This in turn helps in responding to the changes in pressure. Generally, all digital gauges that include a bridge circuit also use a diaphragm. This is to detect capacitance changes in a better way. Some of the gauges also use strain-sensitive variable resistors in bridge circuits to take measurements. Again some use pistons, vibrating elements, micro-electromechanical systems (MEMS), or thin film to sense changes in pressure. A special range of digital gauge use piezoelectric sensors to measure dynamic and quasi-state pressure.
Digital Pressure Gauge varieties as per measurement units
Each digital gauge has the capability to perform various pressure measurements and display amounts in different units. While some of these varieties display measurements in pounds per square inch (PSI), kilo pascals, bars or millibars, some others do so in inches or centimeters of mercury, or inches or feet of water. Again there is a range of digital gauge that displays measurements in ounces per square inch or kilograms per square centimeter.
Digital Pressure Gauge varieties to satisfy your needs
With so many varieties of digital gauge range available in the market, it is really difficult to zero in the one of your choice. The first step towards this is to select one the one that satisfies your individual needs. Look for all the available specifications and optional features, always go for the ones that offer highest accuracy.
To get the best from your digital pressure gauge, it is always advisable to do a little bit of research to get the optimal benefit.
