Tensiometer may refer to one of a number of devices. The two most common are: Tensiometer (surface tension) an instrument used to measure the surface tension of liquids;
The Wilhelmy plate tensiometer requires a plate to make contact with the liquid surface. It is widely considered the simplest and most accurate method for surface tension measurement. Due to a large wetted length of the platinum plate, the surface tension reading is typically very stable compared to alternative methods.
A tensiometer in soil science is a measuring instrument used to determine the matric water potential (soil moisture tension) in the vadose zone. This device typically consists of a glass or plastic tube with a porous ceramic cup and is filled with water .
A classical torsion wire-based du Noüy ring tensiometer. The arrow on the left points to the ring itself. The most common correction factors include Zuidema–Waters correction factors (for liquids with low interfacial tension), Huh–Mason correction factors (which cover a wider range than Zuidema–Waters), and Harkins–Jordan correction factors (more precise than Huh–Mason, while still ...
Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.
A tensiometer is an instrument used to determine the matric water potential (soil moisture tension) in the vadose zone. [10] An ISO standard, " Soil quality — Determination of pore water pressure — Tensiometer method", ISO 11276:1995, "describes methods for the determination of pore water pressure (point measurements) in unsaturated and ...
Bubble pressure tensiometer produces gas bubbles (ex. air) at constant rate and blows them through a capillary which is submerged in the sample liquid and its radius is already known. The pressure ( P ) inside of the gas bubble continues to increase and the maximum value is obtained when the bubble has the completely hemispherical shape whose ...
A tension meter is a device used to measure tension in wires, cables, textiles, Mechanical belts and more. Meters commonly use a 3 roller system where the material travels through the rollers causing deflection in the center roller that is connected to an analog indicator or load cell on digital models.
