The GDS Entry Level Pressure/Volume Controller
(ELDPC) is a general-purpose water pressure source and volume
change gauge. With a maximum pressure of 1000kPa and a volumetric
capacity of 200cm3, the ELDPC fits neatly in the GDS range of
pressure controllers below the premiere product namely the Advanced
Pressure Controller (ADVDPC) and the
mid-range Standard Pressure Controller (STDDPC).
A table of comparison between these controllers can be found on page
2 of the datasheet.

What are its
uses
The ELDPC provides an extremely cost-effective replacement for
conventional soil mechanics laboratory pressure sources and volume
change gauges. It is ideal as a back pressure or cell pressure
source where it can also measure the change in volume of the test
specimen.
In line with existing GDS pressure controllers the ELDPC does not
require a supply of compressed air to function. Configured without
the optional keypad, the device can be controlled directly from a
computer using its own full speed USB 2.0 interface
Using the
Smart Keypad
Configured with or without the smart keypad, the ELDPC may be fully
controlled and data acquired through the USB interface.
With the addition of the optional Smart Keypad the ELDPC can be configured as
a completely stand-alone device. In this stand-alone mode, the
instrument is a constant pressure source which can replace
traditional laboratory pressure sources such as mercury column,
compressed air, pumped oil and dead weight devices. It is also a
volume change gauge resolving to 1 cu mm.
Advantages
The reduced size of the ELDPC compared to any other controller in
the GDS range makes it ideally suited for life in a
commercial testing laboratory where bench space is usually at a
premium. The ELDPC automatically protects itself from pressure and
volume over-ranges.
The ELDPC is fully RoHS Compliant.
