A compound or composite instrument is a setup that combines multiple interdependent sensors to monitor different parameters simultaneously. Each sensor (child) has its own calculation, while the main (parent) instrument defines the loop and direction of data processing. Examples include inclinometers, shape accel arrays, liquid leveling cells, and extensometers — all used for integrated geotechnical monitoring and analysis.
Load cells measure the force or load applied to structural members by converting mechanical force into an electrical signal, which is later calibrated into engineering units such as Newtons or kilograms. They are widely used for determining load in ground anchors, struts, and props within deep excavations, tunnels, and bridges. Load cells provide real-time data to monitor compressive and tensile forces, supporting safety and performance assessments.
Strain gauges are used to monitor strain — the deformation of a material under stress such as steel or concrete. The gauge converts this deformation into an electrical signal, which is then calibrated to represent microstrain. These instruments can be embedded within concrete or mounted and welded on steel surfaces. They help determine load distribution, stress concentration, and structural behavior in applications like tunnels, bridge decks, and pile tests.
