Cracks Tell monitors are simple analog monitoring devices designed to track crack development over time. Key specifications and benefits - Horizontal range: ±20 mm (±0.79") and vertical range: ±10 mm (±0.38") - Provides a clear, defined measurement window for crack monitoring in both directions. - X-Y marks and precision - ±1 mm (±0.04") marks on the X-Y axes - ±0.5 mm (±0.02") discrimination - Enables precise reference points for crack location and growth assessment. - Time-based evolution tracking - A scale is used to quantify cracks and how they evolved over time along the measured axes - Facilitates straightforward trend analysis and historical comparison - Simplicity and form factor - Simple analog design for quick setup and interpretation - Lightweight and unobtrusive for use in lab or field settings What makes it useful - Clear measurement references - The combination of defined horizontal and vertical tolerances with precise axis marks helps users reliably document crack position and progression. - Time progression insight - The built-in scale for tracking changes over time supports monitoring crack growth rate and progression without complex instrumentation. - Easy to use - Designed as an analog monitoring solution, offering an uncomplicated, straightforward approach to crack tracking. Potential use scenarios - In-lab crack propagation studies - Use during controlled loading tests to document crack initiation and growth over time in test specimens. - On-site inspection and monitoring - Deploy for periodic checks of structural components to observe crack evolution and inform maintenance decisions. - Manufacturing quality control - Apply to logs of crack initiation and progression during production or post-process checks to ensure consistency and identify trends. Notes - The description preserves the original terminology and measurements: Cracks Tell monitors are described as simple analog monitoring devices with the specified horizontal and vertical ranges, axis marks, discrimination, and time-evolution scale.
