The
FCO501 Pressure Supply Unit is a self
contained pressure source. It is designed to supply
very stable differential and gauge pressures for calibration,
typically with the Furness Controls PPC500 Pressure
Calibrator.
The FCO501 has an internal air pump to supply a constant
flow to two manual control valves. the Coarse Adjustment
valve sets the full scale pressure, which may be as
low as a few Pascals up to a maximum of 20kPascals.
The Fine Adjustment valve is then used to set the required
calibration steps. the ON/OFF valve allows the output
to be zeroed without disturbing the setting.
When the unit is used in differential mode a special
system, developed by Furness Controls, greatly reduces
pressure instability caused by external pressure variations
due to either unstable atmospheric conditions or to
local effects such as doors being opened and closed.

The
PPC500 provides an outstanding solution
for calibration of pressure instruments. It is independent
of external pressure sources, incorporating a static
dual piston pump, which is matched to the FSD of the
particular model.
Since the PPC500 provides the calibration pressure,
readout of the pressure and readout of the signal from
the test instrument, it can be used for calibrating
transducers, transmitters, or micromanometers within
its pressure range.
An optional built in data logger allows storage of instrument
calibration results within its memory. Results in memory
can then be downloaded to a PC or printed.
The display shows the pressure generated by the PPC500.
Simultaneously it displays the reading from the instrument
under test. This second display can be the actual voltage
or current being produced by the instrument, or it can
display the pressure reading in whatever units the instrument
under test uses. A third display shows the actual percentage
error between the calibrator pressure and the instrument
under test pressure. All this is shown on a large, easy
to read Liquid Crystal Display.
