Pneumatic Drive System [PDS]

            The Pneumatic Drive System [PDS] is used to control the force applied to the MDAC anvil by varying the pressure in its membrane.

          The small size, weight, and portability of the [PDS] allow its use in a variety of environments.

Features :

0 to 200 bars Pressure range.

Digital Pressure display with a 0.01 bar resolution.

Fine and continuous Pressure control with 2 valves ( " IN " and " OUT " )

0.4 l Bottle filled with helium (200 bars) allows for many pressure cycles before reloading.

High pressure connection for the output (on the rear panel): Nova Swiss female for 1/16’’ capillary.

High pressure connection for loading (on the rear panel): Tube ¼’’ Gyrolock female.ortable Size : 260 x 150 x 400 mm; Weight : 6,300 Kg

PDS Accessories


[MEM01(S)] : Membrane (Screw) capillary 1/16" without micro-valve.

[MEM02(S)] : Membrane (Screw) capillary 1/32" without micro-valve.

[MEM03(S)] : Membrane (Screw) capillary 1/16" with micro-valve.

[MEM04(S)] : Membrane (Screw) capillary 1/32" with micro-valve.

            A micro-valve attached to the membrane allows to disconnect the cell from its pressure controller while maintaining the pressure in the membrane.

You work a long distance from your sample. We sell the capillary to lengthen your installation.

            Capillaries of small diameter and low volume can work in cryogenics, they avoid thermal shock on the volume of gas being pressurized.

Automatic Pneumatic Drive System MDAC high pressure cell  [APDS]




BETSA® is in partnership with General Electric® to integrate their Modular Pressure Controllers

in Membrane DAC-based high-pressure setups.

The Automatic Pneumatic Drive System is a modular pressure controller. The APDS controls the force applied to the MDAC anvils by varying the gas pressure applied on its membrane.

The small size and weight, and the portability of the APDS allow its use in narrow spaces.
