These transducers are used to conduct experiments on or pursue research for general buildings, bridges, ground, tunnels, dams and other civil engineering structures. They measure concrete strain, soil pressure, water pressure, stress displacement, inclination and other various physical quantities and convert them electrically. With the use of data loggers it is possible to build an automated multi-point measurement system that operates unattended to gather data for a long time.
