pressure sensors. This could be simply to display the actual force being exerted by a hydraulic ram in a familiar format. Popular Pressure Unit Conversions Step 10: Press Zero to scroll until you see EXIT, and press Select to return to the main display. So we multiply π (3.14) by 6.25 inches (radius of 2.5 inches squared) to get 19.625 square inches as illustrated below. COPYRIGHT © 2020 Automation Products Group, Inc. How To Calculate the PSI to LBS Multiplier for an APG Gauge. Pound/Square Inch : Pounds or pound force per square inch (symbol: psi, lb/in², pfsi or lbf/in²) is a unit of measure for pressure based on avoirdupois units. Therefore, 1 atmosphere is approximately 14.696 pounds per square inch. The manufacturer of the hydraulic ram will sometimes provide the area. In order to get the PSI to lbs multiplier for our motorcycle manufacturing friends, we needed to calculate the piston area of the 5 inch diameter hydraulic ram, it is important not to confuse the area of the piston/bore side and the area of the rod side. The formula for this is: Area = pi X radius squared. 19.625 square inches at 5000 psi (19.625 X 5000) equals 98,125 lbs. The principle behind the process is a simple conversion from one unit to another; in this case the APG digital pressure gauge can convert PSI to lbs. 133.3224. Years ago, a motorcycle design and manufacturing company approached us about using one of our 5000 psiPG7 Digital Pressure Gauges to measure lbs of force from a hydraulic ram. FAQ, Contact Us 1 psi = 144 pound-force/square foot. Tradeshows To convert PSI to lbs, simply multiply the pressure by the area over which the force is applied. Step 9: Press Select to accept the desired custom unit and return to the main setup menu. How to convert pound-force/square foot to psi. Step 3: Press the Select button to access the Units setting options. Step 6: Press the Zero button to change the value of the flashing digit (options: 0-9). The equations below illustrate this. So, when our hydraulic ram is pressing down to full-scale measurement on our 5000 psi gauge, we want it to display 49 tons. Datasheets Careers, ISO 9001:2015 Certification This equals 0.0098, which you enter into the custom multiplier screen on the digital pressure gauge. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. Step 2: Press the Zero button to cycle through the options until UNITS is displayed. A 5-digit conversion factor will appear with the first digit flashing. Privacy & Cookie Policy 1 psi = 0.001 ksi 1 ksi = 1000 psi. News How to convert Psi to Pound Force Per Square Inch (psi to PSI lbf/in2)? Step 5: Press Select to access the Custom Units setting. To convert PSI to lbs, APG Sensors’ digital pressure gauges should be set up to use the "Custom Units of Measure" function, which will allow the sensor to read in pounds. User Manuals To determine the scale factor for tons, we convert the full-scale psi (pounds of force per square inch) to full-scale pounds. Inside the car door, the tyre pressure front and back is listed as 220. what pressure would this convert to in the UK? Once you have determined the correct multiplier for your gauge and application you can set up the gauge to display the desired units. Step 4: Press Zero to cycle through the Units options until CUSTOM is displayed. To convert this to tons, we will divide 98,125by 2000 lbs, or one ton, to get 49 tons. Example: convert 15 psi to ksi: 15 psi = 15 × 0.001 ksi = 0.015 ksi. It is widely used in British and American. As always, let our Measurement Experts know if you have any questions about how to calculate your custom multiplier. pound per square inch. Then, the multiplier for converting psi to lbs needs to be determined, using the area where the force is applied. 19.625 square inches at 5000 psi (19.625 X 5000) equals 98,125 lbs. Convert lbs to tons: To determine the scale factor for tons, we convert the full-scale psi (pounds of force per square inch) to full-scale pounds.
