IA System Measures Multiple Structure Movement
Inertial Aerosystems (IA) has introduced a solution to monitoring and measuring movement of multiple structures and machinery. The system consists of a portable tiltmeter (Model 800P) and a hand-held, battery-powered readout module. The 800P has no moving parts, so needs no maintenance and virtually no calibration. When continuous monitoring is not required, the 800P can be used to make scheduled measurements at an unlimited number of points.
Applications include the long-term movement of structures, foundations and machinery, measuring mechanical response to applied loads, as well as surface levels. Angular position measured with the 800P is referenced to the unchanging vertical gravity vector. The system can operate primarily in two modes; the first is the Tilt Plate Option, where measurements are taken from tilt plates that have been attached to any horizontal or vertical surface. The second mode is the Metrology Option, where the instrument can be manually leveled, enabling the continuous monitoring of any horizontal or vertical surface. Software is available to convert a set of inclination measurements into a contour map of surface relief.
The tiltmeter has an angular range of + or - 5deg from null position with linearity of one per cent of full scale and a resolution of .36 arc/sec. Operating temperature range is -25 to 70C. Measuring 143 x 102 x 127mm, it weighs 2.7kg and is constructed from stainless steel with plastic sensor housing. The readout module powers the tiltmeter and switches the tiltmeter output to the digital display. It measures 111 x 62 x 32mm and weighs 285g. A single 9V battery provides up to 24hrs of continuos tiltmeter operation. This system can be used for surveying surface flatness, settlement, retaining walls, bridges, columns, roofs, tunnels, tanks and machinery.
