The Digital Hydrostatic Profile Gauge is used to monitor the profile of settlement or heave and is predominately used for monitoring beneath embankments or structure where access to the surface is not possible.
For the remote measurement of vertical movement at discrete and inaccessible site location.
The Magnetic Extensometer system comprises a probe, a graduated tapes on a reel and an access pipe along which magnetic targets are positioned. As the prob moves along the access pipe, it detects the magnets by way of a reed switch circuit closing.
The vibrating wire settlement cell measures settlement and heave in soil and rockfill. The cell consists of a vibrating wire pressure transducer connected via a pair of water filled nylon tubes to a hydraulic datum pot located on stable ground.
