Pressure gauges are mechanical or mechatronic instruments that measure and display the pressure of a liquid or gas using one of several measuring technologies: Bourdon tube, diaphragm element, capsule element, etc. The type of technology used depends on the medium being measured, the type of pressure to be measured, and the application. Pressure pu...
Different gauges measure different pressures: • Gauge pressure, or the pressure of a system above atmospheric pressure (positive gauge pressure) or below it (negative gauge pressure or vacuum pressure). • Absolute pressure, or the sum of atmospheric pressure and applied pressure (gauge pressure). • Differential pressure, or the difference between t...
A pressure gauge has wetted parts and non-wetted parts. Wetted parts are components that come into direct contact with the media. In a Bourdon tube gauge, this includes the tube, movement, and pressure connection. The non-wetted parts are everything else: case, bezel (ring), window, pointer, etc. • For standard applications with non-aggressive medi...
The accuracy class of a pressure gauge defines the permissible deviation of the display in percent of the full scale value. Example: For a gauge with a measuring range of 0 … 100 psi and an accuracy class of ±1.0%, if the pressure is 50 psi, the reading could range from 49 to 51 psi. These are the accuracy classes per ASME B40.100: • Grade B: ±3/2/...
Even the most robust gauges aren‘t immune to failure. Here are the eight most common causes of gauge failure: • Mechanical vibration • Pulsation • Extreme temperature • Pressure spikes • Overpressure • Corrosion • Clogging • Mishandling and abuse You can minimize or even prevent pressure gauge failure by using the right type of instrument for the a...
WIKA offers more than 120 models of pressure gauges, and that‘s not counting digital gauges or the variants of mechanical gauges, such as dry vs. liquid-filled, different materials and design features, etc. Some of the criteria to consider include: • The gauge’s nominal size • The media’s temperature • The type of application the gauge will be used...
