Are you still relying on outdated manual tools for measurements? If so, your workflow is likely inefficient and prone to errors. Thankfully, modern smart technologies can be integrated into your operations to reduce time expenditure and the risk of costly inaccuraciesdramatically. One of the ways to use tech at work is with an electronic crack measuring device, a smart instrument that can reduce complexity, cut costs, and improve performance.
Crack-measuring devices are some of the most important measuring devices widely used in the construction industry today. Crack width is measured using visual inspection within the specified range of the device. In contrast, changes in the width can be monitored using fixed gauge sensors designed to measure movements across surface cracks. Other advanced technologies (such as ultrasonic pulse velocity equipment) can also be used for precise crack depth measurement.
Better technologies for precision and accuracy
A digital position strain gauge deformation metre has a digital dial gauge connected to a bar, with a fixed conical point on one end and a moving conical point on the knife edge pivot at the opposite side. The setting out bar positions pre-drilled discs attached to a structure with appropriate adhesives. Every time the crack measuring device reads, conical points insert into holes in the discs, noting the reading on the dial gauge. Strain changes reflect in the dial gauge’s reading.
The gauge on this crack-measuring device requires only minor temperature corrections for changes in the ambient temperature. A reference bar is available for this purpose.
Advanced crack metres
Some of the best crack meters have a vibrating wire to effectively monitor movement across the joints in soil, rock, structures, concretes, and surface cracks.
The crack measuring devicehas a sensor outer body tube and a free-sliding rod within, linked to the internal end and a vibrating wire sensor with a spring. The sensor on the outer body and external end is attached and may be fixed on either side of the crack you’re monitoring.
The crack metre is installed by bolting, grounding, bonding, or fixing an expandable anchor to the structure. Anchors have ball joints on the gauge to enable differential cross-axis movement and to prevent the internal rod from binding with the outer casing.
