The EDS-91 measures settlement or heave in foundations, embankments, fills, excavations etc. This magnetic settlement recorder is accurate, robust, light weight and convenient to use.
The system consists of an access tube, magnet assemblies and a portable magnetic probe with a reed switch. The probe is inserted inside the access tube installed with magnet assemblies at various depths, to detect the change in position of the magnet assemblies due to vertical soil movement. Magnet assemblies suitable for the inclinometer casing are also available. A similar system for monitoring horizontal displacement in embankments is available with a pull cable reel and dead end pulley assembly.
Available with plate and spider magnets to suit different applications and Magnetic probe for taking readings
