Handheld Dynamic Strainmeter DH-14A – Multi-Channel Dynamic Strain Data Acquisition System
The DH-14A is a handheld and battery-operated dynamic strainmeter having 4 measurement channels. Dynamic strain is easily measured while monitoring numerical values and wave forms. Trigger measurement mode and free-run measurement mode are available. The DH-14A is well suited not only for measurement in fieldwork or on moving object, but also for checking sensors and input noise as a checker.
Developed using strain gauge bridge-based technology, this system allows direct input from quarter, half, and full-bridge configurations, enabling flexible connection of various sensor types such as strain gauges, LVDTs, load cells, and thermocouples.
