Description
Measuring pressure is important in the engineering industry,
e.g. in plant, turbomachine and aircraft construction and in process
engineering. Other fundamental factors such as flow rate or flow velocity can
also be determined based on a pressure measurement.
The experimental unit enables the user to measure the
pressure with two different measuring methods: directly by measuring the length
of a liquid column (U-tube manometer, inclined tube manometer) and indirectly
by measuring the change of shape of a Bourdon tube (Bourdon tube pressure
gauge). In a U-tube manometer, the pressure causes the liquid column to move.
The pressure difference is read directly from a scale and is the measure for
the applied pressure. In inclined tube manometers, one leg points diagonally
up. A small height difference therefore changes the length of the liquid column
significantly.
