Details Specifications Ordering Information Documents Geosense Features MEMS In-Place Tilt Meters are designed to measure uniaxial or biaxial tilt, which is measured from the plane(s) perpendicular from the base unit. It is designed to be installed permanently in either the vertical or horizontal position by either bonding or bolting directly to a structure or mounting plate. Data is read via...
Details Specifications Documents Ordering Information Fully grouted installation permits multiple piezometers to be simply and reliably installed in a single borehole. The piezometer string and grout pipe are placed in the borehole and cement-bentonite grout is pumped until the borehole is filled. Multi-point Piezometer Strings allow for multiple Vibrating Wire Piezometers to be connected on a single cable. This facilitates...
Details Specifications Documents The SGP-3400 Series of strain gauge piezometers are designed for monitoring soil pore pressure or changes in water level. They are accurate, highly reliable and suitable for use in harsh environments often found within civil engineering applications including water wells, boreholes, dams, reservoirs, rivers, tanks or any other body of water. The sensor is housed in a...
Details Specifications Documents Simple and economic measurement of groundwater pressures in soil and rock can be carried out using Casagrande type piezometers. Geosense® piezometers are made up of low air entry porous plastic or ceramic elements which are connected to standpipe tubing and lowered into a predrilled borehole. Alternative types may be driven or pushed into soft soil. Where Casagrande...
Details Specifications Documents Ordering Information Geosense TPC-4000 series Total Earth Pressure cells are designed to measure total pressure (effective stress and pore water pressure) in soils and at the interface between structures and the wall of excavation. They are constructed from two stainless steel plates welded around their periphery with the narrow gap between the plates filled with hydraulic fluid....
Details Specifications Documents System Components Ordering Information The Tunnel Profile Monitoring System is a series of linked rods, fixed to the tunnel wall, to monitor deformation. A data logging system and related software is available to provide near real time displacement and generate a graphical representation of tunnel performance. A system of linked arms is affixed to the tunnel wall....
Details Specifications Ordering Information Documents Geosense/RST Vertical In-place inclinometers (IPI) are used to measure lateral displacement of soil and rock or deflection of structures such as diaphragm and retaining walls and piles. They are installed within inclinometer casing which is either placed in a borehole, concreted in or attached to a structure. They consist of a series of wheeled sensors...
Details Specifications Documents The Vibrating Wire Jointmeter is used to monitor joints of mass concrete structures. The instrument consists of two parts, a socket and the main body with a waterproof vibrating wire sensing gauge. During construction of the structure, the socket is secured to the form and embedded into a lift of the block to be constructed. After removal...
Details Specifications Documents The Vibrating Wire Soil Extensometer monitors lateral and longitudinal deformation of soil and different types of embankments and embankment dams. The instrument consists of a vibrating wire displacement sensor encased in a sealed body. The body contains a telescopic outer PVC pipe fitted with two flanges and an inner stainless steel rod. One end of the rod...
Details Specifications Documents VWCM-4000 crack meters are used to measure movement across surface cracks and joints in concrete, rock, soil and structures. They are accurate, highly reliable and suitable for use in harsh environments often found within civil engineering applications including water wells, boreholes, dams, reservoirs, rivers, tanks or any other body of water. The sensor consists of an outer...
Details Specifications Documents The VWDT-5000 series of vibrating wire displacement transducers cover displacement ranges up to 300 mm and are fully waterproof to a minimum of IP68 (16 bar external pressure). They can be incorporated into many displacement products such as crack and joint meters, rod extensometers, convergence meters, soil extensometers and displacement meters. VWDT-5000 transducers are particularly rugged, and...
