Sensors and DAQPartition an automated test bench across a precision DMM, digital oscilloscope, and modular DAQ using IEEE 1241 ENOB, NPLC power-line rejection, CAT II isolation, and sensor bandwidth.
Sensors and DAQSize strain gauge amplifier gain, excitation power density, 6-wire Kelvin remote sensing, DC vs AC carrier demodulation, anti-aliasing filters, and shunt calibration.
Sensors and DAQMatch a thermocouple, Pt100, or NTC to the DAQ using IEC 60751 ranges, ASTM E230-87 tolerances, and the excitation current that heats the sensor.
Sensors and DAQReduce rectangular 0/45/90 and delta 0/60/120 strain gauge rosette readings to principal strains and direction, with an assumed-reading angle example.
Sensors and DAQCompare quarter, half and full strain gauge bridges by output, gauge placement, temperature cancellation and bending rejection, with a worked voltage-ratio example.
Sensors and DAQCheck leadwire resistance symmetry, terminal roles, bridge offset nulling, and shunt calibration placement on a three-wire quarter-bridge strain gauge channel before logging.
Maximizing Value at NI is an independently operated information site about test and measurement. It offers vendor-neutral explainers on data acquisition, sensors, embedded systems and industrial automation for engineers choosing and using test equipment.
