Constant Pressure Source Soil Test Equipment
All GDS controllers are designed for use as constant pressure sources. The stepper motor constantly adjusts itself to ensure the desired pressure is maintained, with the additional advantage that volume change is measured to 1 cubic mm* (*except the pneumatic controller which only regulates pressure and has no capability for measuring volume change or flow).
The following soil test equipment can perform the Constant Pressure Source soil test:-
