Vibrating Wire Crack Meters are an essential tool used to monitor the size and development of cracks in various building materials. Surface cracks and joints in concrete, rock, brick, and other building materials are important for ensuring structural integrity. Therefore, accurately measuring and monitoring the size and movement of cracks is critical for the safety and durability of structures. The anchoring fixtures at both ends of the sensor are used by attaching them to both sides of the crack to accurately measure its size and movement. Equipped with vibrating wire technology, these sensors provide extremely precise measurements for examining cracks.
The operating principle of the sensors is based on the vibration of a tensioned wire at its resonant frequency. As the crack size increases or changes shape, the distance between the two ends of the sensor changes, causing a variation in the resonant frequency of the vibrating wire. This change is measured with high accuracy through a magnetic coil to determine the size and movement of the crack.
Moreover, VW Vibrating Wire Crack Meters are easy to use and have a wide range of applications. They are commonly used not only in buildings but also in dams, bridges, tunnels, and other infrastructure projects.
