altimeter
An altimeter is an instrument used to
measure the altitude of
an object above a fixed level. The measurement of altitude is
called altimetry, which is related to the term
bathymetry, the measurement of depth underwater.
and
Altitude is the elevation of a point or object
from a known level or datum (plural: data).
and the relation between altitude and pressure is
Atmospheric pressure decreases as altitude increases. This
principle is the basis of operation of the pressure altimeter,
which is an aneroid barometer calibrated to indicate altitude
instead of pressure.
So in actual fact, barometer can be used as an altimeter. Your
question is a bit too general. There's no such thing as the
barometer cannot handle too much pressure; the maximum is designed
manually by humans.
May I know where you get your question from? Is it from any exam
papers? If so, post the whole question.
