Enterprise Level Pressure Volume Controller

Product Code : ELDPC

The GDS Enterprise Level Pressure/Volume Controller (ELDPC) is a general-purpose water pressure source and volume change gauge for the precise regulation and measurement of fluid pressure and volume change.
The enterprise level controller is aimed at commercial testing and is available in one configuration, 1MPa pressure and 200cc volume. Liquid (normally deaerated water) in a cylinder is pressurised and displaced by a piston moving into the cylinder. The piston is actuated by a ball screw turned in a captive ball nut by an electric motor and gearbox that move linearly on a ball slide. Click here to read our controller comparison.

Further Information:
Key features of GDS controllers Benefits to the user
Does not require a supply of compressed air to function: GDS pressure controllers do not rely on lab air supplies.
Controlled with or without a PC: The GDS pressure controllers can be controlled directly from a computer using the USB 2.0 interface and GDSLAB or with the Smart Keypad (optional for ELDPC) the controller can be configured as a completely stand-alone device.
Accurate measurement: Pressure is measured by an integral pressure transducer. Volume change is measured by counting the steps of the incremental motor.
GDS controllers automatically protect themselves from pressure and volume over-ranges: All GDS pressure controllers are self-protecting and can also be programmed to protect any attached equipment.
Controllers are an ideal back-pressure source: Allowing the measurement of change in volume of the test specimen with no requirement for a separate volume change device.
Controllers can be used with different media: The ELDPC, STDDPC and ADVDPC run using water or oil and GDS have an ADVDPC (1000cc) specifically for use with Air.
