VS-Pro Vacuum System
The VS-pro series of vacuum systems from UMS are capable of applying a constant or tension-controlled vacuum for long-term monitoring projects. Keyboard display allows for status checks and configuration without hooking it up to your PC.
The Constant Vacuum Method
The constant vacuum method is continuously maintained by a regulated vacuum pump. The vacuum can be set between atmospheric pressure and 85 kPa.
Tension Controlled Extraction
A tensiometer measures the soil water tension. The programmable vacuum station VS automatically supplies a vacuum in correspondence to the measured tension. Due to the numerous functions of the unit an optimal adaptation to the sampling task is possible.
Applications
Long term monitoring
Defined pore water sampling
Defined leachate measurements
Lysimeter sites
Tension controlled sampling
Benefits
LCD Display and keypad for basic status check and configuration
Continuous display of readings and status on the LCD
LCD backlight and multicolor LED
High accuracy vacuum pump
Two vacuum outputs
Selectable constant or tension controlled vacuum
Optimized for use with batteries or they can be hardwired and plugged into your power supply.
Option for tensiometer input: T8, T4, or T5
Multiple configuration options
Integrated datalogger

TensioLINK USB converter
The tensioLINK USB converter is used for directly connecting sensors and devices with serial tensioLINK to a PC. One can configure features and read out measured data.
UMS devices with 8pin M12 connectors (e.g. TS1 or T8 tensiometers) could be directly connected to the converter without the need for a further power supply. The sensor is powered through the USB interface.
Use with the PC-Software tensioVIEW. Manual Software and Driver come along with supplied CD.
| Sensor Supply | 9 VDC / 100 mA tolerance +1 V |
| Short circuit | 2 Min. |
| Galvanic isolation | 1 kV |
| Serial sensor interface | RS485-2 wire, ESD protection 15 kV |
| USB interface | compliant to USB 1.1 und 2.0 |
