Hydraulic Anchor Load Cells

Reference products codes: L2M0, L2E0 Hydraulic anchor load cells are used to monitor loads in tiebacks, rock bolts and retaining walls. They consist of two ring-shaped stainless steel plates welded together around their circumference. The anular space between the plates is filled under vacuum by deaired oil. The load is directly measured by a Bourdon […]

Electric Anchor Load Cells

Reference products codes: L200, ELC420 Electrical resistance anchor load cell consists of a ring-shaped stainless steel body which incorporates from 8 to 16 electrical resistance strain gauges in full bridge configuration. Typical applications include performance testing of anchor systems in tunneling or deep excavations. The cell design minimizes the sensitivity to the eccentric load. Anchor […]

Earth Pressure Cells

Reference products codes: L141, L143 Earth pressure cells (or total pressure cells) are used to monitor total pressure in earthfill dams and embankments or placed at the interface between the structure and the wall of excavation. Earth pressure cells are constructed from two stainless steel plates, welded together around their pheriphery. The anular space between these […]

Hydraulic Pressure Cells

Reference products codes: L111, PK45H, P252A, TUNY Hydraulic pressure cells are designed to measure stress in mass concrete or placed at the interface between the structure and the wall of excavation. The pressure pad consists of two steel plates welded together around their periphery and spaced apart by a narrow cavity saturated under vacuum with […]

Flat Jack Testing Accessories

Reference products codes: L100 The flat jack consists of a steel pressure pad filled with deaired oil equipped with two steel tubes, one for pump connection and one for linking another pad or to mount a pressure tranducer. Pressure pad are available in different dimensions; customized pad shape and dimensions achievable under request. The manual […]

Urban Tunnelling: Hakata station of the Fukuoka city subway – Japan

For the tunnel excavation of the Hakata station of the Fukuoka city subway in Japan partial excavation was carried out. A road with heavy traffic and different structures , as subground car park, gas pipelines, important sewers, are situated above the tunnel construction. Taking into account constraints as shallow overburden and unconsolidated ground above the […]

Bözberg Railway Tunnel anchor load monitoring retaining wall

The new Bözberg railway tunnel will serve as a 4-meter corridor that will be added to the Gotthard route in order to promote transalpine freight transport from road to rail. The largest sub-project within this plan is the replacement of the existing Bözberg tunnel in Switzerland with a new twin-track tunnel. Sisgeo has supplied since […]

Optical Pendulum Readout

Reference products codes: S9RTB Optical coordinometer is a device designed to detect the coordinates (X-Y) of the plumb line on a horizontal surface. The measuring principle is based on high-accuracy photecells able to detect the pendulum wire position: the coordinates are read with the IP67 dial gauge fixed on the coordinometer. The instrument can be […]

T-1000 Telependulum

Reference products codes: S911, S912 T-1000 Telependulum was designed to take automatic readings of the coordinates of pendulum’s plumb line. Thanks to the new optical technology, without any moving part, it allows very high accuracy and resolution, wide measuring range and the possibility to measure plumb lines with different diameters. T-1000 can be settled and […]

Direct And Inverted Pendulums

Reference products codes: S911, S912 Hanging pendulums are designed to monitor horizontal movements in dams, dam foundations, abutments and to determine the structural movements of bridges, piers, towers and tall buildings. The direct pendulum consists of a steel wire anchored at the upper end to the structure, with a tensioning weight suspended at the lower […]

Tilli Portable Tiltmeter

Reference products codes: SCLIN TILLI is a portable tiltmeter. It consists of a rugged stainless steel frame with aluminium sensor housing containing the MEMS technology inclinometer. The surfaces of the frame are machined to allow an accurate positioning of the tiltmeter during measurements. Measurements can be done on horizontal or vertical surfaces. Readings in two orthogonal […]

Tilt Beam (TB) sensors

Reference products codes: S700, S7BM Tilt Beam (TB) sensors can be used both in chain to measure a continuous displacement or in stand alone application to measure the tilt-displacement between two point (ends of the beam). As all Sisgeo’s MEMS tilt sensor, they use the latest MEMS technology that grant great performance and low temperature dependance. TB […]
