Soil tensiometer with transducer A420

An Analog Tensiometer, is principally identical to any other Tensiometer, with one major difference: Instead of having a mechanical gauge there is an Electronic Vacuum sensor which we also name Analog Transducer, that transmits, via cable, vacuum readings to a computerized monitoring or control system. Main uses: -Continuous, long term follow-up of soil moisture changes with no need of physically being on site. -Viewing data anywhere, anytime, by various devices, Such as P.C. Smartphones, Tablets etc.. -Optional Automatic irrigation start/stop according to soil water condition. Ami-Tens' Analog sensors are using standard electronic outputs (4-20mA or 0-2V), which are compatible to most monitoring or control systems available in the market. Specifications: The device's body – it is the same as all Ami-Tens' tensiometers, whereas beneath the transparent window there is a TEE connector in which the Analog Transducer is screwed. ​ On top of the device there is a screwed cap for refilling water. The Analog Vacuum Sensor (Transducer) Its body is a stainless-steel Cylinder (L=6cm or 10 cm, D=2 cm), with a G1/4" threaded connection. Electro-Mechanical details: The Transducer converts Physical values (water tension) to electrical standard outputs. There are 4 basic models, differing from each other by the output mode and the measuring range: For most mineral soils: a) 4-20mA output, range of 0-100cb b) 0-2V output, for range of 0-100cb For soilless media or sand: c) 4-20mA output, for range of 0-20cb. d) 0-2V output, for range of 0-20cb.
