UMS T5 TENSIOMETER

The T5 Tensiometer is specially made for punctual measurements, for example in soil columns, small lysimeters or pots. With an active surface of only 0, 5 cm2 and a diameter of 5 mm the ceramic tip has all advantages of small dimensions: little soil disturbance, punctual pick-up and fast response. The special version T5x can achieve a measuring range of 200 kPa. The T5 can be installed in any position and orientation. Bubbles are easily detectable through the transparent shaft. Output signals are balanced. Typical Applications Punctual measurement of water potential Miniature lysimeter studies, together with micro samplers and soil temperature probes Determination of pF/ wc and K/ Psi in soil columns, soil cores or soil sampling rings Determination of leachate and capillary water movements Controlling irrigation Pot experiments Measurements in the upper soil horizons in the field Monitoring with data loggers Spot readings with the INFIELD7 Advantages Accurate zero-tension reading Fast response: With sufficient fillingthe T5 responds within 5 seconds to an applied air pressure change of 0 to 85 kPa Most standard T5 reach a range of at least 150 kPa when delivered. Limitations Not for dry soils Not frost resistant In the field applications require impact protection Technical Information Measuring range + 100 kPa ... -85 kPa Output signal -100 ... + 85 mV Accuracy ± 0.5 kPa Supply typ. 10.6 VDC / 1.3 mA Shaft Ø 5 mm Shaft length 2 ... 20 cm Corpus Ø 20 mm, length 3.5 cm Cable 1, 5 m; 4-pin plug M12 Included in Delivery T5 in carrying case refill tools Manual
