Precision crack meter for monitoring joint and crack movements in concrete structures using vibrating wire technology.
The Geolook Vibrating Wire Crack Meter is designed for long-term monitoring of crack width changes and joint movements in concrete, masonry, and rock structures. It provides highly accurate, stable measurements essential for assessing structural integrity over extended periods. The sensor features a robust stainless steel construction with mounting anchors for easy installation across cracks or joints. The vibrating wire transducer ensures excellent long-term stability with minimal maintenance, making it ideal for inaccessible areas or harsh environments.

A Vibrating Wire Crack Meter is a displacement sensor specifically designed to measure the widening or closing of cracks and joints on structural surfaces. It consists of a sensor body and a target (or two anchors) installed on opposite sides of a fissure.
As the distance between the anchors changes due to structural movement, the tension in the internal wire changes. This change in tension alters the wire's resonant frequency, which is measured by a readout unit or datalogger and converted into millimeters of displacement.
A vibrating wire crack meter operates on the principle that the resonant frequency of a tensioned wire changes when the tension in the wire changes. The instrument typically consists of a sensor body containing a stretched magnetic steel wire and a spring mechanism, which is anchored across a crack or joint.
As the crack opens or closes, the relative movement between the anchors causes a change in the tension of the internal wire. If the crack widens, the tension increases; if it closes, the tension decreases. This physical change is directly proportional to the displacement being monitored.
To take a measurement, an electromagnetic coil within the sensor plucks the wire, causing it to vibrate at its natural resonant frequency. This frequency is then detected by the coil and transmitted to a readout unit or datalogger. The readout converts the frequency signal into a precise displacement measurement (typically in millimeters) using calibration factors specific to the sensor.
Since the output is a frequency signal rather than a voltage or resistance change, the data is immune to electrical noise and cable resistance effects. This makes vibrating wire crack meters exceptionally stable and reliable for long-term monitoring over long cable distances.
