​Wire deformeters measure the changes in distance between two fixed points, one being the transducer sensor and the other a fixed anchor point connected via a tensioned Kevlar or stainless-steel cable.

A movement in settlement or horizontal deformation changes the distance between these two points and is recorded by the sensor. Resulting in Wire deformeters being used for a range of applications including; displacement measurements, deformation monitoring, convergence monitoring in tunnels, cracks and fault monitoring in historic buildings and monitoring rock and landslide movement.

  • Battery life of 4 years when reading on 1h frequency

Operation

Electrical wire deformeters are available in either a potentiometer (4-20mA) or vibrating wire (frequency / VW) transducer housed in a IP68 Stainless steel enclosure for analog data of deformation. The stainless-steel cable attached to the anchor point is run through a pulley, enabling the transducer and the anchor to be mounted on different planes, even perpendicular, increasing its suitability to a variety of situations and applications.

USB wire deformeters consist of a IP65 aluminium enclosure housing a rotary potentiometer and logger connected to a tensioned steel cable with 80mm of range. Movements between the fixed wire deformeter and the corresponding eyebolt anchor is recorded as a change in distance, stored data in the logger is then received using a mini-USB cable. ​
