ExplainerAn HVAC relative-humidity sensor helps observe moisture conditions in rooms, ducts and equipment spaces, but placement and interpretation decide how useful the reading is.
ExplainerAn HVAC zone temperature sensor measures local room or air temperature for building monitoring and control, but its placement and system design determine what the reading really tells you.
ExplainerLearn how a noncontact inductive turbopump shaft-displacement sensor measures shaft movement, why cryogenic conditions complicate the reading, and where the instrument fits in rocket-engine development testing.
ExplainerHow an ESA-proposed rocket-engine leak detector combines electrical conductivity and temperature evidence to identify possible liquid-propellant leakage without treating either signal as proof on its own.
ExplainerA plain-English guide to how a thrust load cell or dynamometer measures engine force on a rocket ground-test stand, and how it differs from pressure, vibration and flow sensors.
ExplainerA plain-English guide to valve-actuator position transducers: what they measure, how test teams record the signal and why position is not the same as valve control.
ExplainerA beginner-friendly explanation of how a propellant flowmeter helps monitor rocket-engine ground tests, what its output represents and why the instrument must be read as part of a larger data system.
ExplainerSee how a magnetic float switch can mark propellant tank-volume intervals during rocket ground testing, and why it is not the same as a continuous flight mass gauge.
ExplainerHow NASA research uses FBG and OFDR fibre-optic sensing to study launch-vehicle strain and temperature, and why the sensor is best understood as part of a larger measurement system.
ExplainerA beginner-friendly explanation of how structural strain gauges capture launch-vehicle deformation during development flight tests, and why strain is not the same as load.
ExplainerA plain-English guide to rocket vibration sensors, piezoelectric and IEPE accelerometers, turbopump monitoring, test data and practical limits.
ExplainerA beginner-friendly explanation of how resistance temperature detectors support rocket-engine test measurements, how their signal chain works and where thermocouples differ.
ExplainerHow a thermocouple temperature probe measures hot and cryogenic locations in rocket propulsion tests, and why wiring, signal conditioning, installation and calibration matter.
ExplainerA beginner-friendly explanation of how a differential-pressure transducer compares two pressure points during rocket propulsion testing, and why the reading needs the right ports, calibration and acquisition chain.
ExplainerA plain-English guide to how a dynamic combustion-pressure sensor helps test teams observe fast pressure changes and combustion-instability signals without confusing it with a static pressure instrument.
ExplainerA beginner-friendly explanation of how static pressure transducers observe propellant tanks, feed systems and rocket-engine tests, including absolute, gauge and differential references.
ExplainerA plain-English explanation of what a GNSS/GPS navigation receiver contributes to a rocket’s navigation data, and how that differs from an IMU.
ExplainerA plain-English guide to the specialist microphone arrays used around rocket-engine static fires to measure acoustic pressure and map where test-stand noise comes from.
ExplainerA rocket IMU combines accelerometer and gyroscope data so onboard navigation systems can track motion and rotation during flight.
ExplainerA rocket gyroscope measures angular rate as part of an inertial measurement unit. Here is how that rotation signal fits into launch-vehicle avionics, and what it cannot measure alone.
ExplainerA plain-English explanation of what a rocket accelerometer sensor measures, how it differs from an IMU, and why navigation and flight-test instrumentation are separate jobs.
ExplainerA laptop display colorimeter measures on-screen colour patches so calibration software can build a profile for more consistent creative work.
ExplainerA plain-English guide to optional laptop magnetometer hardware, derived compass headings, calibration, interference and the difference from a lid Hall sensor.
ExplainerA laptop gyroscope sensor measures rotation rate, not location or absolute heading. Learn where a gyrometer may appear, what Windows can do with it, and why orientation is usually derived.
