Instrumentation: Test and Measurement Methods and Solutions

Tilt Measurement: Tilt measurement is fast becoming a fundamental analysis tool in many fields including automotive, industrial, and healthcare. Navigation, vehicle dynamic control, building sway indication, and motion detection systems
all rely on this simple, cheap, and precise way of angle monitoring. MEMS accelerometers are better suited to inclination measurement than other methodologies. This session will address the challenges encountered when designing a dualaxis tilt sensor using a MEMS accelerometer including measurement resolution, signal conditioning, single- vs. dual-axis, angle computation, and calibration.

Impedance Measurement: The measurement of complex impedance is widely used across industrial, commercial, automotive, healthcare, and consumer markets, and can include applications such as proximity sensing, inductive transducers, metallurgy and corrosion detection, loudspeaker impedance, biomedical, virus detection, blood coagulation factor, and network impedance analysis. This session will cover the concepts, approaches, and challenges of performing complex impedance measurements and will present a system-level solution for impedance conversion.

Weigh Scale Measurement: Most common industrial weigh scale applications use a bridge-type load-cell sensor, with a voltage output that is directly proportional to the load weight placed on it. This session examines the basic parameters of a bridge-type load-cell sensor, such as the number of varying elements, impedance, excitation,
sensitivity (mV/V), errors, and drift. It will also discuss the various components of the signal conditioning chain and present solutions with high dynamic range.
