Dwyer Photohelic Pressure Gauge & Switch. 3-in-One Indicating Gage, Lo-limit and Hi-Limit Control. Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic design. The Photohelic measures and controls positive, negative or differential pressures of air and compatible gases.
The PV diagram shows a gas going from a smaller to a bigger volume, while the pressure stays constant. â¢ Since the volume of the gas increased, we know work was done by the gas. â¢ The arrow has been added to show the way the process went from start to finish. â¢ If you look at how we calculated the work done, you might notice that it would have been the same answer if we had calculated the area under the graph. The area under the line on a PV diagram is the work done! This is true for any PV diagram, so keep it in mind.
