 Inertial Aerosystems has added a portable tilt meter to its range for measuring mechanical load responses and movement in structures
Inertial Aerosystems has introduced a new, low cost, solution to monitoring and measuring movement of multiple structures / machinery. The system consists of a portable tilt meter (Model 800P) and a hand held, battery powered, readout module (Model 870). Manufactured by US based Applied Geomechanics, 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. Simply position the tilt meter on the surface to begin measurements.
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 levelled. This enables 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 tilt meter has an angular range of + or - 5 degrees from null position with linearity of 1% of full scale and a resolution of .36 arc seconds. Operating temperature range is -25 to 70 degrees C. 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 tilt meter and switches the tilt meter output to the digital display. A single 9 volt battery provides up to 24 hours of continuous tilt meter operation. Measures 111 x 62 x x 32 mm and weighs 285 grammes.
This innovative system can be used for surveying Surface flatness, Settlement, Retaining walls, Bridges, Columns, Roofs, Tunnels, Tanks, Machinery.
