EDS-40D weldable strain gage, a precision strain gage with high frequency response, suitable for dynamic strain/stress monitoring. It is commonly called dynamic strain gage.
 
Dynamic strain gages play a vital role in measuring structural health monitoring. They are specially designed for installation on the structural steel membrane, on which the stress/strain needs to be monitored, by spot welding.
 
The strain gage generates a bridge signal output (mV/V) proportional to the stress on the structure. Model EDS-40D weldable strain gage is a strain gage of choice over vibrating wire strain gages in applications where stress changes very fast and dynamic monitoring is required. With the provision of waterproof installation, the dynamic strain gage are most suitable ones for long term reliability, when installed in hostile environments such as in bridge applications.
