DYNA Force® Elasto-Magnetic Sensor
DSI supplied 240 DYNA Force® Sensors for Penobscot Narrows Bridge, Maine, USA. Each cable had six sensors, allowing the cable forces at each stage of construction to be monitored. Periodic lift-off operations were additionally carried out on the strands with sensors, and a good correlation was observed. The bridge is now open to traffic, and the forces in all cables can be monitored anytime using DYNA Force® Sensors without any disruption to traffic.
