Encardio-rite crack meters and joint meters are ideally suited for the measurement of movement. These measurements are important for monitoring the behaviour of civil structures and buildings
The crack meter is used to measure the change in width of a surface crack. It is used to monitor cracks in concrete structures, rock, bridges
, pavement slabs, etc. The joint meter is ideally suited for the measurement of displacement/movement across joints, such as a joint opening between two concrete/masonry blocks in a dam
Encardio-rite offers the following type of mechanical type crack/joint meters. The electric versions are also available for automatic readings and wireless data transfer.
The EDJ-40C crack meter is ideally suited for measuring the change in width of a surface crack to a resolution of 0.5 mm. It is integrated with a graduated scale and a transparent acrylic plate with a hairline cursor mark. The assembly when installed across the crack, the graduated scale and cursor move relative to each other depending upon the crack opening or closing.
Model EDJ-40C2 is a biaxial mechanical crack meter with a marking of ±25 mm (x-axis) and ±10 mm (y-axis). It is ideally suited for measuring the change in width of a surface crack to a resolution of 0.5 mm, or shearing.
The model EDJ-41M is used for monitoring cracks, joints and fissures. It consists of two stainless steel round datum blocks that are installed on either side of the opening. Each datum block has a groove on the surface along the circumference to assist in taking readings.
Encardio-rite model EDJ-40TJ triaxial crack/joint meter is used for surface measurement. Surface crack/joint measurements can be made either on the surface or at locations accessible from galleries (in case of dam).
