It turns out that plenty of types of infrastructure, especially those that have serious implications for public safety, are equipped with instruments to track their performance over time and even save lives by providing an early warning if something is going wrong. Engineers keep an eye on strain, vibrations, temperature, pressure, tilt, flow rate, and more to make sure that structures behave like they were designed and to keep people safe from disaster.
