Profile: Slope Indicator manufactures a range of geotechnical and structural sensors for monitoring tilt, displacement, pressure & strain. Our products include inclinometers, extensometers, strain gauges, tiltmeters, tape extensometers, c rackmeters, full size data logger, pneumatic indicators and terminal boxes. Our single data logger can read a large number of sensors provided they are concentrated into a small area. Additional loggers should be deployed if sensors are distributed over a wide area. Our tiltmeters are used to monitor changes in the tilt of a structure. Such changes may be caused by excavation, tunneling, dewatering, or loading of the structure. Our tape extensometer is used to detect and monitor changes in the distance between two reference points.
