dConv

A high accuracy displacement sensor that can be calibrated with hardware to monitor roof to floor convergence station in salt and potash mines, but can also be used to measure dilation of crack and joint closure in structures such as walls, bridges and dams.  

Fully compatible with our BluLink solution which transforms it into a wireless instrument and provides local data-logging. For very long range applications involving a distributed array of d-Conv instruments, as are common in salt and potash mines, a mesh network of 900MHz radios are commonly used.
