I’m looking for a gauge that will display force of a hydraulic press when reading pressure and converting based on a 1.75″ diameter ram piston. Is there a gauge that can do this?
We would suggest using the DM01 digital pressure gauge and configure a custom pressure unit via the software which is an optional extra available with the DM01.
The following explanation will walk you through the process of determining the conversion factor to create a custom pressure unit.
Since you will use the pressure and the area of the ram piston to calculate the applied force, you will need a pressure gauge which enables you to configure a custom pressure unit. Since the area is constant, you just need to apply the multiplying factor to the pressure reading to convert it to a force reading.
F(lbs) = P(psi) x A(sq in) = 1psi x π x (1.75/2)² = 2.40528lbs
So the multiplying factor to use to create a custom pressure unit would be 1 lb = 1/2.40528… psi = 0.415752… psi
For some pressure gauges you may need to use a pressure conversion value in different units such as bar or pascals so you will need to convert this value again using a pressure converter. Try to use more digits in your calculations than the number of displayed digits to make sure you do not introduce any significant rounding errors.
Alternatively you could use this pressure and diameter to force calculator and derive the force reading from the pressure reading and ram piston diameter.
For example if you wanted to convert a 3000 psi ranged pressure gauge to read force, these would be the conversion values:
