Displacement Transducers
PI Shape Displacement Transducers
The PI displacement transducer features a straightforward design, consisting of strain gauges mounted on an arch-shaped spring plate.
It is available in three models, with gauge lengths ranging from 50 mm to 150 mm.
This transducer is used to measure the crack opening displacement over each gauge length on concrete surfaces, as well as to measure displacement in various structures.
