Draw-wire displacement sensor NOVA TRF100

potentiometeranalogIP67

Wire displacement sensors are used to detect and control any movements that occur in landslides or in unstable rock masses. The tool essentially consists of a box containing a rotatory potentiometer and tensionator for the steel cable, and an anchor that has to be fixed at the second reference point. A steel cable is stretched with constant voltage between the two reference points of the instrument. The maximum length of the steel cable may be up to 10 metres. • Monitoring large displacements • Testing of floors and coverings • Monitoring topple landslides • Convergence measurements • Reliability on long time monitoring • High resolution and accuracy • Class of protection IP67 • Sturdy construction, also suitable for harsh environments • Easy to install
