- Innovative design: The lower plate consists of overlapping plates that are carefully calibrated to millimeter precision, while the upper plate is transparent and marked with precise crosshairs for accurate monitoring. - Precise measurement scale: Equipped with XY axes offering divisions of +/-1 mm (about +/-0.04 in) and a resolution of +/-0.5 mm (about +/-0.02 in). It provides a horizontal range of +/-20 mm (about +/-0.79 in) and a vertical range of +/-10 mm (about +/-0.38 in) for comprehensive monitoring. - User-friendly installation: The crack monitor features redesigned mounting posts that securely connect the two panels. This design eliminates the need for adhesive and simplifies installation, improving ease of use and stability. - Extended functionality: This standard crack monitor for building walls is designed to track wall cracks and their development over time. It serves as a precise tool for monitoring structural integrity and uses overlapping plates to enable detailed measurements. - Use scenarios: - In new construction, monitor crack formation and movement on exterior or interior walls during early stages. - In retrofit or heritage projects, assess crack progression over time with a noninvasive monitoring approach. - After seismic events or heavy loading, quantify crack evolution and the structural response for safety assessments.
