2 T-5312 Product Bulletin
The system consists of a
remotely located transmitter, a
receiver-controller and an
indicator all connected by air
pressure piping. A double fitting
for supply air is used to provide
air pressure to the receiver-
controller and, through a field
supplied .007 in. (.18 mm)
restrictor, to the remote
transmitter. Variables such as
humidity, temperature, electrical
current and voltage fluctuations
which may affect electric and
electronic transmission signals
have no effect on pneumatic
transmission.
Operation
As the pressure signal from the
remote transmitter increases or
decreases, it is measured by the
element diaphragm of the
T-5312. The pressure change at
the diaphragm is transmitted to
a system of levers that open and
close the control port. This
causes the output pressure of
the T-5312 to change according
to the transmitted pressure
signal change.
The sliding control port rail is
marked DA (Direct Acting) at the
top and RA (Reverse Acting) at
the bottom. Moving the sliding
control port upward (DA) or
downward (RA) from the mid-
point on the slider rail increases
the gain for proportional action
applications and decreases the
differential for two-position
applications.
Mounting
The T-5312 is designed for
surface mounting; use barbed
fittings provided for air
connections.
