The crack measuring device is used for accurate and easy crack detection, developed on the concrete's structures because of deterioration. These devices are bonded onto the structure, and then an optical fiber is connected to switch on the light source. Unfortunately, the optical fiber gets disconnected when the structure develops, and the light leaks from that part. Light leakage allows users to know the exact position and occurrence of the crack.
Features of Crack measuring device
· Easy to discover the cracks – No additional knowledge is required to control or manage structures to check the cracks.
· The device’s light emission indicates cracks generation even from those areas where it is difficult to check visually, such as a dark place, an elevated area, etc.
· Detecting the size of the crack accurately. The device can measure cracks as small as 0.05 to 0.3 mm. It allows engineers to detect and repair the cracks before they grow bigger.
· Ideal for concrete structures
Crack measuring device benefits
· Fully-automated and eco-friendly device
· Identifies the cracked parts at their initial stages
· Durable and solid design
· Easy to integrate into the production line
· Automation with the help of gantry, conveyor, shuttle, or inter-linkage
· Extendable to accommodate the test criteria like pores, shrinkage cavities, etc.
· It can also be used for external control measuring system
Measuring Method
The device is bonded onto a structure, and then optical wirings are connected. During the regular check, one of the light sources is connected to a fiber cable connector to observe the cracked point visually. There is no need for a power supply here. The light source is too light and small, and the object can be checked easily without any damage.
Application of Crack measuring device
The Crack measuring device has multiple applications. It is efficient in cracks because of the deterioration of RC or PC bridges. It can also detect cracks in the tunnel's lining concrete, connection section of the tunnel's rigid frame, and box culvert structure. You can also use it for detecting cracks in concrete structures, large concrete piles, and more.
