The SE-86 Static Strain Test and Analysis System, a compact and intelligent data acquisition system with channel self-checking function, can be used to build a comprehensive test system with tens of thousands of channels, suitable for the measurement of various signals, such as stress, strain, voltage and displacement, easy to use, suitable for indoor and outdoor measurement and test.
Modular design, used for distributed measurement or the construction of thousands of channel test system
Advanced isolation and reasonable grounding technology are used to realize strong anti-interference ability
Software-settable of full-bridge, half-bridge, public compensation quarter bridge and three-wire quarter bridge
Support the function of auto measurement and correction of wire resistance, intelligent wire identification and self
check of bridge configuration
