Ram pressure5/27/2023 Whatever your needs, H J Kirby Corp provides custom gauge dials for your hydraulic or pneumatic press or for any force application and in any units. The area of that rod has to be deducted from the area of the piston to come up with the “effective area” used to calculate force. However, the pneumatic press on the right has a top rod that reduces the area of the piston that the air pressure can work on. The hydraulic press on the left uses a single rod piston so the hydraulic pressure on top can be applied over the entire diameter of the piston or ram. Obviously, it's important for your dial to be accurate. So 1000 PSI on that piston would generate 28274 pounds of force or just over 14 Tons. Since a circle has an area of πr2 where r is the radius (diameter/2), the area of a piston is not generally as easy as our 18 sq in Ram above. So there might be an 8¼” Ram for instance, or a 10” ram. made presses use round pistons with standard English system diameters, usually measured to ¼”. Either way, that gauge is now married to that press. If your operator needs to read in pounds, then the dial can read 0-36000 pounds force, instead of tons. For our example, we would want a custom dial that displayed BOTH 0-2,000 PSI and 0-18 Tons on 18 sq in Ram. (The force scale is only applicable to that specific area of piston.) If this is normal operating pressure then a custom dial might be necessary.įor safety and longevity of the equipment, the dial should display twice the expected range. So if the piston (aka Ram) has an area of 18 in2 and we put 1000 PSI (lbs/in2) on top of the piston it will exert (1000 x 18) or 18000 Lbs ( 9 tons) of force to the platens. If we know the area of the piston we can solve the above equation like this: F = P x A. However, if we put a gauge on a specific hydraulic (oil driven) or pneumatic (air driven) press, we might like to know how much FORCE is being applied between the platens. Perry’s Engineering Handbook tells us P (Pressure) = F (Force) / A (Area). A Ton is equivalent to 2000 pounds force. Pressure, by definition is force applied over an area. Pressure gauges, by design, measure pressure. Let's explore those Force Pressure Gauges for a moment. While there are many stocked gauges that may meet your needs, sometimes, a custom gauge is needed for a Force Pressure Gauge. Need to understand Tons on Ram or Force Pressure Gauges? We have you covered.
