The most familiar product ranges supplied at PCTE are NDT and Laboratory equipment for concrete and construction. What our customers may not know is that PCTE supplies a range of instruments for geotechnical applications and structural monitoring, including strain gauges, tilt meters and beams, piezometers, and the focus of todays article portable and in-place inclinometers.
Inclinometers can be used to measure the relative displacement in ground and of structures that lie beneath ground. Inclinometer tubing is cast into boreholes. An inclinometer probe passed through the entire length of the tube records inclination vs depth which is displayed in terms of horizontal or angular displacement.
Some applications are to monitor lateral earth movements to predict landslides in unstable slopes, monitor roadway embankments and retaining walls and they may also be utilized to measure deflection of shafts, piles, excavations, tunnels, etc.
Geosense's Portable MEMS Inclinometer needs only a phone or tablet to enable tilt data from the probe to be saved, emailed or transferred directly to external services using API or FTP. Models are available for horizontal, vertical and inclined applications.
Packages will include an elongation-resistant cable, slimline detachable probe and a lightweight reel with Bluetooth and a storage case for probe components.
The MEMs biaxial sensors and signal conditioning board complies to industry standards and are fitted into the probe to allow calibration factors to be stored in the probe. Double Kevlar reinforced cable and depth markers were designed and tested with weight up to 40kg.
A portable inclinometer does not provide continuous monitoring, information as the slope movement is unknown until the inclinometer is lowered into the borehole.
When using In-place inclinometers the slope movement is monitored continuously and with the right communication hardware can be logged, or presented via web service.
Geosense's in-place inclinometers, extension rods and cables connect with a single twist double lock joint, that links the hardware firmly and connects the data cables between sensors.
If only critical measurements are needed lengths of inclinometer rod and sensor may be extended with wire rope system components to place sensors only are required depths.
