The following differential pressure sensor uses a matched pair of strain gauges. As the differential pressure increases, one strain gauge…
A strain gauge is a device used to measure the strain (compression or expansion) of a solid object by producing…
A strain gauge is an array constructed from thin metal film designed to increase resistance as it is stretched and…
A pressure gauge is supposed to accurately indicate applied pressure over its full calibrated range. Bourdon Tube Pressure Gauge In…
Some bourdon tube gauges are equipped with a very small spiral spring attached to the pointer shaft: Bourdon Tube Gauge…
Suppose a pressure gauge uses a diaphragm as its pressure-sensing element, like this: Pressure Gauge This mechanism will work, but…
One challenge technicians face when calibrating low-pressure instruments is how to generate very low air pressures to simulate different low-pressure…
A very useful principle in physics is the Ideal Gas Law, so called because it relates pressure, volume, molecular quantity,…
A device called a manometer is a very simple and yet very precise pressure measuring instrument. It works on the…
Shown here is a diagram of a standard pressure gauge, based on the pressure-sensing action of a hollow, C-shaped metal…
