The SE-86H High-speed Static Strain Data Acquisition Instrument, with a maximum sampling rate of 100Hz, is widely used in fatigue test and pseudo-dynamic test, which can capture the slow-changing signal of the whole process from the elastic region to the plastic region. In addition to the measurement of stress and strain signals, physical quantities such as voltage, displacement and temperature can also be measured.
The acquisition instrument can be built into a distributed measurement system or a large rack test system as required
RS485 bus is used for data transmission between power/controller and DAQ unit, and network port is used for commu-
nication between power/controller and computer for real-time sampling, transmission, storage and display
External DC power supply is supported to facilitate on-site measurement and test
Software-settable of full-bridge, half-bridge and three-wire quarter bridge, easy to use
Support the function of auto measurement and correction of wire resistance, intelligent wire identification and self
check of bridge configuration
