ISSO-CR Vibrating Wire Crackmeters
The ISSO–CR displacement sensors are designed to monitor linear movements on structural surfaces. Sensors allow you to control the opening of cracks, expansion joints, and the movement of movable structural elements relative to each other. The sensitive element is a metal string. The sensor housing is made of stainless steel. The movement of the sensor rod leads to a change in the tension force of the string. Two electromagnetic coils located inside the sensor excite the string and read the resonant frequency of vibrations from it.
The case is cylindrical, sealed, designed for operating pressure up to 1 MPa.
The measurement accuracy is 0,5%. The displacement is measured by stretching the rod, which causes an increase in wire tension proportional to the linear displacement.
