5. Instructions
Cut the silicone hose into sections of the
required length.
Using the lengths of hose, make the pressure
connections between the sensor box and the
Stirling engine.
Note the "positive" and "negative" labelling of
the hose connections - connect the hoses
correctly according to the effective direction
of the pressure.
During the experiment, check that no elastic
expansion of the hose is occurring – this can
cause the pressure reading to be lower than
the correct value.
