The Crackr is a product for online monitoring of buildings where cracks have formed, or for monitoring expansion joints.
The two parts of the Crackr are applied on either side of the crack
We have designed the two parts of this product to mount with the correct initial distance from each other. The orange spacer is removed after both parts are screwed to the wall.
A set of shims can be used if there is an uneven surface.
StabiAlert has placed a number of magnetic sensor elements in a specific array above a magnet. Using mathematical algorithms, three vectors are calculated that show the 3D movement of a crack. The CrackR wakes up at an adjustable measurement interval and transmits the collected sensor data. In this way, the battery can last up to ten years, depending on the interval. By using the sensors, the costs are significantly reduced.
