The hydrostatic pressure is transmitted to the diaphragm by a hydraulic jack associated with a frictionless ballscrew driven by a precision DC motor. The rotational speed and the position of the motor are servo-controlled by means of an optical encoder ensuring a perfect control of the fluid flow rate together with the determination of the displaced volume of fluid.

Sample tightening system:
•A large pneumatic jack enables an accurate and reproducible tightening.
•The tightening surfaces have an adequate profile to minimize the slippage even for difficult materials like textiles for high volume bags.
•The tightening pressure is measured with a precision manometer and may be displayed in metric or imperial units.
•The gripping strength is recalculated according to the geometry of the tightening surfaces, and displayed in newtons.

Bursting pressure measurement:
•The pressure is measure by a metallic gages pressure transducer (0 to 100 bars)
•Accuracy: +/-1% of read value +/-1 digit between 5% and 100% of the FSD.
•Resolution: 2 mbars (50,000 points)

Some important features of this tester include:
•Large graphic LCD
•Software available for easy data transfer to Excel and other spreadsheets
•Pneumatic sample clamping
•Menus allow programming to meet pre-defined test methods and international standards.
•Predefined test methods may be stored and recalled.
