Part 10: How Do I Rescale a Sensor to Use With an Oscilloscope?

Sensors are commonly used in automotive, motor, and other applications to measure rotational speed, shaft angle or position, torque, pressure, wheel speed, crankshaft speed, oxygen levels, anti-lock braking system (abs) parameters, temperature, magnetic or electrical fields (Teslas, Webers, Siemen, Volt/meter, etc.) and many others.

In this coffee break webinar, we will describe various techniques used to take sensor outputs and rescale them into appropriate and useful non-voltage scientific units, such as Pascals, Volt/meter, Webers, Newton-meter, revolution/minute (RPM), etc. for display as an easily understandable waveform on an oscilloscope.

Topics to be covered in this webinar:

  • Principles of unit conversion in an oscilloscope
  • Simplest use case – converting to Ampere (A) units
  • Converting to other units for sensors with voltage outputs
  • Complex sensor unit conversion (Resolvers, Quadrature Encoder Interface or QEI)
  • Sensor unit conversion with serial data outputs and digital-to-analog conversion (DAC)
