FORCE OF RAM PRESSURE HOW TO
How To Calculate The Force Applied By The Hydraulic Ram 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. The formula for this is: Area = pi X radius squared. In this case, the force is calculated by determining the area of the bore/piston side as this is where the hydraulic fluid pressure is concentrated by the hydraulic pump. 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. How to Calculate the Area of the Hydraulic Ram When not provided, the area will need to be calculated.
The manufacturer of the hydraulic ram will sometimes provide the area. Then, the multiplier for converting psi to lbs needs to be determined, using the area where the force is applied. 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. Lbs of force, however, is not a unit of pressure displayed by our gauge therefore, the custom unit converter function that is built into all of our gauges needed to be used. Years ago, a motorcycle design and manufacturing company approached us about using one of our 5000 psi PG7 Digital Pressure Gauges to measure lbs of force from a hydraulic ram. How to Convert PSI to lbs Using an APG Digital Pressure Gauge: To convert PSI to lbs, simply multiply the pressure by the area over which the force is applied. PSI is a unit of measure for pressure, and pressure (PSI) is the amount of force (lbf) applied per unit of area (in2). The trick to understanding how this conversion works is to break it down into its base units. 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. APG gauges are able to display the pressure readings in a few industry-standard units as well as many other units for force by using a simple conversion factor or multiplier. This could be simply to display the actual force being exerted by a hydraulic ram in a familiar format. In a hydraulic system, it is often beneficial to not only display the pressure in the system but to also display the force being exerted by a hydraulic ram.
