The wire deformometer is usually used to monitor and measure movements in landslides by measuring two points distant from each other.
The instrument is made from the protected sensor in a sturdy aluminum box, by a non-deformable wire constantly kept in tense by a tensioning device and a fixing device to fix the other end of the wire to the measuring point.
The instrument is composed of a sensor protected by a sturdy aluminum box, and a non-deformable wire constantly kept tense by a tensioning device and a fixture securing one end of the wire to the measuring point.
The crackmeters or wire deformometers made by Pizzi Instruments are both with a potentiometric sensors and vibrating wire sensors.
Pizzi Instruments offers both wire deformometers with potentiometric sensors or with vibrating wire sensors.
The choice of sensor depends on the specific requirements of the monitoring project and the type of application If required by our customers, we are able to suggest the best solution for a specific application Instruments with different wire lengths are available, depending on the specific requirements of the installation site.
The wire deformometer, connected to an automatic acquisition system, allows real time monitoring and measuring of landslide movements, together with the possibility of managing local and remote alarms if thresholds are exceeded.
The wire deformometers can be read manually with our portable units (DEC 3000 and handheld unit Dec5 for vibrating wire sensors) or automatically with our dataloggers (CUM3000 or /and VW Brick 2 or VW Brick 8, or CRio VW, depending on sensor type).
Our joint meters can be integrated into automatic monitoring systems and manage phenomena and alarms locally and remotely in real time.
For specific needs and requests, we are able to develop and manufacture customized products different to standard.
