Large
central
air
conditioning,
refrigeration
equipment,
in
order
to
achieve
automatic
control
of
the
machine,
the
lowest
energy
consumption
ratio,
the
operation
of
the
equipment
needs
to
be
fully
monitored,
such
as
temperature,
refrigeration
medium
pressure.
The
pressure
sensor
mainly
measures
the
pressure
of
the
refrigerating
medium
online
on
the
refrigerating
equipment,
and
transmits
the
pressure
to
the
control
system
of
the
main
machine
in
the
form
of
electrical
signals,
so
as
to
reflect
the
compression
operation
state
of
the
equipment,
to
realize
the
automatic
control
of
the
product,
and
to
reflect
the
consumption
of
the
equipment
as
soon
as
possible.
