In-place Inclinometers, Beam Clinometers
Sisgeo In-place Inclinometers, Beam Clinometers

Product Features
 
  • In-place inclinometer (IPI) sensors are designed for automatic monitoring of critical locations.
  • Jointed together and suspended inside the casing where deformation may occur, a string of IPI sensors allows to monitor the continuous profile of the inclinometer casing.
  • Vertical and (sub)horizontal in-place inclinometers are equipped with magneto-resitive contactless pendulum, solid-state accelerometer or forcebalanced servo-accelerometer sensors.
  • Sisgeo In-place Inclinometers, Beam Clinometers separated signal cable is required for each IPI, but also a group of IPI can be linked together to have a single multicore cable output






Digitalized In-Place Inclinometers
Sisgeo Digitalized In-Place Inclinometers

Product Features
 
  • Sisgeo Digitalized In-Place Inclinometers designed for automatic monitoring of critical locations.
  • They use the RS-485 serial communication protocol: this technology allow to use only one cable to connect all the probes in one chain.
  • The performances of this system are amazing, thanks to the self-compensated MEMS technology sensor and to the completely new engineered electrical components.
  • Jointed together and installed inside the inclinometer casing where deformation may occur, a string of digitalized IPI allows to monitor the continuous profile of the inclinometer casing and of the related soil mass.

 







Surface Clinometers
Sisgeo Surface Clinometers

Product Features
 
  • Sisgeo Surface Clinometers essential for the control and security of structures in elevation, both during the construction phase than in operation.
  • Thanks to the new MEMS self-compensated sensor or the force-balanced servo-accelerometer sensors, Sisgeo clinometers ensure high accuracy and negligible dependence on thermal factors.
  • They can be read locally using a portable readout or centralized with a datalogger for remote monitoring.
  • Applications: Monitoring of inclination changes due to civil or industrial activities, retaining walls and diaphragms movement, monitoring of buildings damaged from earthquake, and small dimensions for a lower visual impact on monuments and historical buildings






Pendulums System And Tel-310s Telependulums
Sisgeo Pendulums System And Tel-310s Telependulums

Product Features

 

  • Sisgeo Pendulums System And Tel-310s Telependulums designed for automatic readings of the coordinates of the pendulum plumb lines (direct or inverted).
  • Characterized by high resolution and the possibility of measuring many steel wire simultaneously.
  • Auto-diagnostic functions for measurements validation through a built-in high performance software.
  • Either local readings by portable PC or remote operation via RS-485 serial interface are possible.
  • Also implemented with 4-20 mA output for ADK-100 network application.
  • The new version of TEL-310S Telecoordinometer (3rd generation) offer: wide measuring range: 60x145mm; waterproof components IP68 until 50kPa (5m water head); flexible structures for easy maintenance; remote auto-diagnostic through log file; and high level built-in software for statistical data elaboration and validation.






RDS Railway Deformation System
Sisgeo RDS Railway Deformation System

Product Features
 
  • A non-conventional monitoring system designed by Sisgeo for automatic survey of longitudinal deformation of the rail tracks and the twisting of sleepers.
  • Sisgeo RDS Railway Deformation System to monitor the rail track geometry as: longitudinal level: measured in “mm” as a difference of level between two points located longitudinally at certain preset intervals; transversal alignment: measured in “%” as inclination change of two sleepers located at the same intervals of longitudinal.
  • Compared to the traditional systems, including topographic surveys, RDS offers to the Customers either high performances and significant reduction of the operating costs.
  • In fact when the system is correctly installed there is not field activity required by technicians at site; RDS can be managed also by a single operator on the Web.






BRS Magnet Extensometers
Sisgeo BRS Magnet Extensometers

Product Features
 
  • A system – based on British Building Research technique – for measuring either settlement or heave at various depths in soil, embankments, earthfill dams and dikes.
  • Sisgeo BRS Magnet Extensometers consists of access tube with external corrugate pipe, magnet rings, telescopic bottom section with datum ring and suspension head.
  • Magnet rings (targets) are fixed, externally to the access tube, in the ground where movement may occur.
  • Magnet rings move together with surrounding soil along the axis of the access tube.
  • Readings are obtained with a portable readout, lowering the reed switch probe through the access tube.
  • Comparison of surveys taken over time provide profiles of ground settlement or heave.






T-REX Incremental Extensometer
Sisgeo T-REX Incremental Extensometer

Product Features
