Stand-alone wireless crackmeter for remote crack monitoring. Resolution: 0.01 mm / 0.1°C / 1% RH.
Record the maximum/minimum variation on graduated scale. Accurate to 1/10th of a mm.
For graphic recording of structural yielding. To be mounted on the G3 Gauge. This new device records the maximum and minimum distortion on the graph.
Saugnac Gauges, experts in precision crackmeter for the building industry, offer specific tools for measuring and monitoring cracks remotely.
In a conventional crack monitoring operation on a building, the expert inspects the site regularly to check the state of the crack and record the crack indicators.
During these regular inspections, the professional takes measurements and photos to document the progress of the disorder. All this data is taken in the field, which means that you have to travel to the site, which is expensive. Are there any alternatives? The answer is yes.
Remote crack monitoring is entirely possible with the right equipment in the area to be monitored.
One solution is to use a connected crackmeter to monitor changes in crack spacing remotly. The device takes measurements using its sensors and sends its data by connecting to the network. The data can be viewed from a computer or a connected mobile device. Remote monitoring of cracks can therefore be carried out without constraint for several years. The solutions offered by Saugnac Gauges have a battery life of up to 7 years.
A second mechanical solution consists of using a mechanism that uses a graphite lead to record changes on a scale. This solution, which has the advantage of being less expensive, does not record every point, but only the minimum and maximum values.
The recording of the evolution of a crack remotely with a connected device can be set to a frequency of every 4h, 6h, 8h, 12h or 24h. Depending on the data sending frequency set, the connected crackmeter then wakes up to transmit the stored data from the 3 sensors into the app.
Disorders also appear on structures that are difficult to access: on a high façade, on a bridge or viaduct, or on the vault of a building with a high ceiling… In these conditions, each measurement taken with the naked eye requires either a specific intervention by rope access technicians or the use of equipment such as a cradle or scaffolding.
In order to reduce intervention time and costs, it is possible to use a remote crackmeter with sensors to carry out remote monitoring.
