VK702NH-BRG Ethernet 24-bit Strain/Bridge DAQ 1.Features The VK702NH-BRG is an Ethernet-type high-speed strain gage pressure bridge signal acquisition card with 8-channel (4-channel for the -4 type) true differential inputs, 24-bit resolution, a maximum single-channel sampling rate of 102.4ksps eight-channel synchronization for a total of 819.2ksps (409.6ksps for the -4 type), precision preamplification, and the excitation source required by the integrated bridge transducer. Hardware support features. This product uses a number of high-precision 24-bit ADC units and with the company's many years of accumulated development of the front differential amplification module, so that the product has a high speed, high resolution, high accuracy, ultra-low noise, high rejection ratio, wide measurement range, low temperature drift advantages, suitable for precision and high speed acquisition of a variety of occasions to use. LAN communication adopts TCP/IP and original exchange communication protocol and built-in anti-packet loss algorithm, which can ensure the stable transmission and acquisition without losing data for a long time. Acquisition card expansion for series version, USB type, WIFI wireless type and so on. VK702NH-BRG acquisition card all components are industrial grade, using all-metal shielding, can adapt to the strong industrial interference occasions, and has the advantages of moisture-proof, shockproof and anti-interference. 1.2 Property Listhigh precision high resolution24bit resolutionUltra-Low Noise Pre-Differential Amplifierminimum measurableuVhigh-rate synchronous acquisitionsingle channel highest102.4ksps(102.4kpoints per second),8channel is819.2kspssupportSDstorageonline/Offline/timing/Condition Triggered Storagemultiple measurement modesbridge sensor/voltage/currentsupports multiple inputsstrain force sensor,Full bridge sensor,voltage, IEPE/ICPacceleration/Audio Sensor, 0 ~ 20mALoser Range20mV, 100mV, 1V, 5V, 10Vmultiple rangesIntegrated Excitation Source Convenient direct precision power sensormultiple trigger modes IOPort/analog quantity/timing/software triggercount/frequency measurementcounting or frequency measurementmetal shielded enclosure Strong anti-interference ability ​ ​ ​​​​​​​Common Problems and TroubleshootingProblem Descriptionexclusion methodOther instructionsUSBdriver installation relatedfirst useUSBconnect the computer, make sure the light is on.
