Draft range pressure sensors are used
to measure low gauge and differential
pressure in a wide variety of industries,
including hospitals, pharmaceutical
production facilities, semiconductor
and fiber optics manufacturing, as well
as in research and development. Such
low pressures are referred to as draft
range because they are pressures that
can be produced from a draft. Most of
the applications involve preventing an
environment or manufacturing process
from being contaminated. Because the
pressures measured by these types of
sensors are very low, calibrating them
accurately can be a challenge.
