Pi-shape Displacement Transducer
PI Pi-shape Displacement Transducer ±2mm to ±5mm
The PI displacement transducer has a simple structure; which considered an arch-shaped spring plate with strain gauges mounted on it.. Six models designed for gauge lengths of 50 mm to 300 mm are available. This transducer is used to measure the crack opening displacement occurring within each gauge length on the surface of concrete or to measure the displacement of various structures.
