Sensors and DAQ
Sensors and DAQDynamic Versus Static Strain Gauge Measurement: Range, Fatigue, and Zero Drift
Compare dynamic versus static strain gauge measurement across monotonic microstrain range, cyclic S-N fatigue life, thermal output zero drift, and excitation limits.
Sensors and DAQDMM vs Oscilloscope vs DAQ: Automated Test Bench Architecture
Partition 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 DAQStrain Gauge Amplifier and Signal Conditioning: Gain, Excitation, and Bandwidth
Size 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 DAQThermocouple vs RTD vs thermistor for a DAQ input
Match 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 DAQStrain Gauge Rosette: Principal Strain and Orientation
Reduce rectangular 0/45/90 and delta 0/60/120 strain gauge rosette readings to principal strains and direction, with an assumed-reading angle example.
