Digital Pressure Gauge
Digital pressure gauges are attached to an instrument that measures the pressure of a gas or liquid and gives numerical readings. They display readings in digital, rather than analog, form. Digital readouts are typically easier to read and provide greater accuracy. They usually run on batteries.
Digital displays are available on most kinds of pressure gauges. Some common types of pressure gauges include air, water, oil, and fuel pressure gauges. Automobiles and machinery require many of these gauges in order to run smoothly. Some digital pressure gauges can make adjustments automatically depending on the reading.
Gauges typically use a Bourdon tube to measure pressures 15 psi or more. A Bourdon tube is a thin walled elastic tube of metal that is flat and formed into a C-shape, which flexes in response to an increase in pressure. When a pressure change occurs, the metal tube flexes, inciting movement of the gauge indicator. Digital pressure gauges are used in numerous industries and can be used to help contain and monitor hazardous materials.
