Abstract: The present invention provides a water tension sensor with a non-sintered core that allows batches of similar and standard sensors to be manufactured in a simple manner, for operation with air and with an air flow outlet, which sensor can be used to read water tension and trigger dripping. The sensor according to the invention is ideal for manually reading soil water tension and for automating irrigation systems based on a static pressure or gas propulsion mechanism.

Abstract: A pressure measuring and flow-rate controlling device includes: a flattening plate including a fluid cavity in the flattening plate; a flexible contact membrane provided on said flattening plate; a support member configured to secure the flattening plate against a sample; a pressure adjuster; an inlet tube connected to the pressure adjuster at a first end of the inlet tube, the inlet tube connected to a first end of the fluid cavity at a second end opposite to the first end of the inlet tube; and an outlet tube connected to a second end opposite of the first end of the fluid cavity, where the pressure adjuster is configured to control a flow rate of a fluid passing through the fluid cavity based on cell pressure of the sample.

Abstract: The invention relates to a system for measuring cell turgor pressure (dendroturgometer), which can also operate as a firmometer. The system can also be used as an automatic dripper, wherein in this embodiment it is kept pressed by means of a flattening plate (1) against the organ (4), as well as by employing a brace (6) provided with a spring (5) that applies stable force of a magnitude higher than the product between the water pressure, regulated by a pressure adjuster (10) and the fluid layer (2) under the membrane (3), on which the plant exerts compression and obstructs the water flow. The dripping is started when the transpiration provides a drop in the cell turgor pressure of the plant, so that the resulting pressure will be lower than the adjusted water pressure. This system may also be miniaturized and used for measuring the vegetable turgor pressure by using water pressurization with an plunger (11). The cell turgor pressure is achieved with a pressure transducer (12), as the lower pressure applied that forces the passage of water through the layer (2). Alternatively, the system may be mounted for operation as a dendroturgometer in a closed system with a cover (13), and a pressure transducer (12), while a brace applies press force with a spring (5) to enable continuous reading of the turgor pressure in the stern.
