Body
The T-5800 Series Receiver-
Controllers are designed for use
with remote temperature,
humidity, or pressure transmitters
(connected to the controlled
variable “CV” input) to provide
precise control of pneumatic
devices. These receiver-
controllers are capable of
providing restricted supply air to
low volume remote transmitters,
thus requiring only one air line
connection between the two
instruments. In addition, the “CV”
input can accept the transmitted
output of any pneumatic device
which has a calibrated output of
3 to 15 psig (21 to 105 kPa),
such as a process transmitter.
The T-5800 is available in single
or dual input models with
proportional or proportional plus
integral (PI) control. In addition
to the above mentioned
features, all adjustments are
made on the face of the unit.
These adjustments include the
gain, local set point (when
selected), ratio (dual input
models only), master input
balance (dual input models
only), and integral time (PI
models only). The action and
readjustment are field selected
by interchanging the placement
of the tube ends from one lower
spigot to the other lower spigot
(see Fig. 5). The hypodermic
needle test points provide
convenient test pressure checks
for the set point pressure “SP”,
controlled variable pressure
“CV”, and master input pressure
“M” (dual input models only).
Proportional-Only Control:
T-5800-1 & T-5800-3
Over the years, proportional-only
control has been an acceptable
means of controlling variables
such as discharge air
temperature, humidity, water
temperature, and pressure. A
