SINGLE FIBER TENSIOMETER
It is made to measure the contact angle of a single fiber to find out how wet it is. It comes with a force sensor with a high level of accuracy. Features: The surface tension and interfacial tension of liquids are measured. Figuring out the weight of liquids.
Working:
The tensiometer measures the contact angles made by the liquid on the fiber as it moves forward or backward. When the fiber comes into contact with the liquid, there is a change in the forces acting on the fiber. The tensiometer records this change as an increase in height, which means that the fiber is at a depth of zero.
An optical tensiometer takes pictures of drops and automatically figures out what shape the drops are. The shape of a drop depends on the surface tension of the liquid, the force of gravity, and the difference in density and humidity between the sample liquid and the medium around it.
Force Tensiometers measure the surface tension, interfacial tension, and density of liquids using a simple and reliable method.
The supposed tensiometer can be used to measure the negative pressure or matric potential. The tensiometer is made up of a liquid-filled porous cup that is mostly made of ceramic. A liquid-filled tube links the cup to a pressure measuring device like a mercury manometer or vacuum gauge.
Advantages:
Tensiometers are cheap and can be used more than once. They’re easy to use, but they do need some maintenance out in the field. To take care of it, you have to add water and use a hand vacuum pump to get the air out of the tube.
How things work:
- The K100SF tensiometer uses the Wilhelmy method, which measures the capillary force that a liquid puts on a solid surface.
- The test liquid is dipped into the substrate, which is then taken out of the liquid. During this process, the forces that the liquid puts on the substrate are measured and used to figure out a series of dynamic contact angles.
- In practice, the substrate is attached to the fixed holder, and the vessel stage moves up (advancing) or down (receding) at a constant speed (between 0.1 and 500 mm/min).
