User Manual

• Pump out the air between the plates.

• The force acting on the Magdeburg plates can be

determined by the equation Force = Pressure x

Area. It should be noted that some residual air

remains between the plates that acts against the

atmospheric pressure. This should be considered

when calculating the force:

Force = (Atmospheric pressure – Residual pressure)

x Area

• Use the pressure sensor to work out the pressure

due to the residual air between the plates.

• Measure the atmospheric pressure using a barom-

eter.

• Calculate the area in m² from the inner diameter

of the ring.

• Perform your calculations.

• Repeat the experiment using the second sealing

ring and compare the results.
