Pressure / volume maintainer - Soilmatic E

Pressure range: 0 - 1MPa (0-10 bar)

Volume capacity: 230cc

Interface: Touchscreen or USB connection

The Proeti Pressure/Volume maintainer is a general-purpose water pressure source and volume change gauge for the precise regulation and measurement of fluid pressure and volume change. Available in one configuration, maximum pressure of 1000kPa and a volumetric capacity of 230cm3

The pressure / volume maintainer 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.

The unit does not require a supply of compressed air to function. Configured both with or without the touchscreen, the device can be controlled directly from a computer using its own full speed USB 2.0 / 3.0 interface.

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 mm3.

The reduced size compared to any other controller in the Proeti range makes it ideally suited for life in a commercial testing laboratory where bench space is usually at a premium. The pressure / volume maintanier automatically protects itself from pressure and volume over-ranges.

EDS software supplied allows full controller functionality to be accessed by means of the full speed USB 2.0 interface. The software allows the user to program “n” pressure steps that can be either incremental or decremental, this is very useful to program a saturation.

The instrument may also be controlled via the touchscreen without the need of a PC.
