Wire crackmeters enable precise monitoring of changes in distance between two fixed points of up to 30m with a range of 2000mm.
Due to its ability to monitor displacement variations, it is commonly used in applications to monitor landslides, mass rock movement, embankments along with surface and foundation faults and cracks, associated with settlement and horizontal displacement.
This type of crack measuring device, also known as a wire extensometer, operates using rotary electronic sensor (transducer) connected to a tensioned wire that extends to an opposing fixed anchor point, commonly an eye bolt. Both transducer enclosure and wire are supplied in stainless steal accompanied by a galvanised base plate for mounting, providing a robust crack measurement tool able to be installed in a variety of applications.
