Device for Measuring the Consistency and the Setting Time of a Grout

Abstract

The article presents the design and construction of a penetrometer, device that measures a material’s resistance to penetration, which helps determine its strength, consistency, or firmness. The device consists of standard components, including a needle, fixed load, and measurement system. The novelty of the design lies in the integration of a microcontroller that controls needle release, measures penetration depth, and displays the results. The lifting and lowering of the loaded needle are performed by an electromagnet, which has an additional function - it is also used to measure the depth of penetration into the material.
