Data loggers are designed to measure static strain, a phenomenon where the subject strain does not change at all or slowly changes as seen in load tests on large-scale structures. Static strain is often measured in several hundred channels and under dozens of load conditions. These systems can be provided in stand-alone or PC-controlled systems depending on the application.
- Simultaneous measurement of various static variables
- Visual presentation of the status of measurement and function
- Compact and lightweight design
- Data collection through internet or Ethernet LAN
Strain amplifiers are usually used for dynamic strain measurements. Dynamic strain measurement requires response, stability, SN ration and high resistance against external noise.
