Page 3: Introduction
Air bubbles are easy to recognize and eliminate through the acrylic head with vent screw. The tensiometers can be installed in any position. They are ideally suited to determine the soil moisture tension in experimental setups in the laboratory. The Tensio 140 is characterized by its long and robust shaft. -

Page 7: Under Which Conditions Can A Tensiometer Be Used
Tensiometer of UGT GmbH, are not bound to these limits and cannot fall dry due to innovative operating principles. The ceramics of the UGT tensiometers have by default an air entry point of at least 85 kPa. This value slightly varies for every ceramic and depends next to the maximum pore size also on the state of the ceramic and on substances dissolved in the water. - Page 8 Umwelt-Geräte-Technik GmbH | Eberswalder Str. 58 | D-15374 Müncheberg | phone: +49 (0) 33 43 2 - 89 575 | www.ugt-online.de Page 8 of 12...

Page 12: Pressure Readings
4.3. Pressure Readings The Tensio 140 provides an analog output signal between 0 and 1 V. To transform the output signal into a pressure value the signal range (0 – 1 V) has to be transferred linearly to measurement range of the pressure transducer (+0.3 bar to –...
