Wire Deformeters
The wire deformeters are designed to monitor changes in the distance between two anchor points. Typical applications include monitoring cracks or displacements in civil structures. Electrical wire deformeters are analog devices with either vibrating
wire or potentiometer transducers. A stainless steel wire connects the transducer to the opposing anchor. The USB wire deformeter is a digital device that records readings from a rotary potentiometer. A steel wire connects the device to the opposing anchor.
