How is psi measured

OK close. What is PSI? Come on, Fullbay, you may be saying, everyone knows what PSI is. Dude, Fullbay…we know that, too. We know that you know. And we know that you know that we know.

For reference, 1 PSI equals 6, Pressure measurement instruments such as pressure gauges and sensors typically display measurements in PSI. PSIG is the term for pressure specified by a gauge or other pressure measurement device.

It gives the difference between the pressure in a pipe or tank and the pressure of the atmosphere atm. You can use the actual atmospheric pressure value for your location if it is available, or you can also use Unless you live at high altitude or in a deep valley, the sea level value will work. In other words, since atmospheric pressure at sea level is As an example, absolute pressure at sea level is It is important to note, however, that depending on the maximum pressure of your gauge, the measurement might be too long to fit on the 4-digit digital display of the.

You will need to do some quick math to ensure the maximum measurement will fit on the pressure sensors display. To do this, we multiple the maximum PSI of the digital pressure gauge by the previously calculated area. In our example with the motorcycle company, we would multiply the maximum output of the PG7 PSI by the area of the hydraulic ram To determine the scale factor for tons, we convert the full-scale psi pounds of force per square inch to full-scale pounds.

To convert this to tons, we will divide 98,by lbs, or one ton, to get 49 tons. So, when our hydraulic ram is pressing down to full-scale measurement on our psi gauge, we want it to display 49 tons. To get the multiplier that you'll enter into the gauge to display tons, divide the tons calculated above 49 by the psi full scale This equals 0. You can now move on to the programming steps. Once you have determined the correct multiplier for your gauge and application you can set up the gauge to display the desired units.

Step 5: Press Select to access the Custom Units setting. A 5-digit conversion factor will appear with the first digit flashing. Step 6: Press the Zero button to change the value of the flashing digit options:
