Sensors and DAQ
Sensors and DAQStrain Gauge Wheatstone Bridge: Quarter, Half and Full Compared
Compare quarter, half and full strain gauge bridges by output, gauge placement, temperature cancellation and bending rejection, with a worked voltage-ratio example.
Sensors and DAQThree-Wire Quarter-Bridge Checks: Lead Resistance, Balance and Calibration
Check leadwire resistance symmetry, terminal roles, bridge offset nulling, and shunt calibration placement on a three-wire quarter-bridge strain gauge channel before logging.
Sensors and DAQDAQ Ghosting Test Checklist: Single Channel vs Scan
Compare single-channel and scanned readings, then vary timing, order, and voltage steps to test suspected DAQ ghosting with a blank observation record.
Sensors and DAQCold-Junction Sensor Placement: Checking Terminal Temperature in a DAQ
Locate the thermocouple-to-copper transition, check the selected CJC source, and record terminal temperatures before diagnosing a drifting DAQ channel.
Sensors and DAQConnecting a 4–20 mA Sensor to a DAQ: Current Inputs and Shunt Checks
Copy the wire count and the DAQ input type before you pick a shunt or a supply. Leave ohms, supply voltage, and loop resistance blank until the manual states them.
