Question
What is linearity of Ultrasonic Sensors?
Answer
Linearity is the error in the linear output compared to the ideal value that describes the relationship between the distance and the linear output when the temperature and voltage are at fixed values.
 
      (Example)
The linearity of E4PA-LS50-M1 Ultrasonic Sensor is ±1% FS (FS: 500 mm − 60 mm = 440 mm). 
Converting this to a dimension,
Dimension error = ±1% × 440 mm= ±4.4 mm
Therefore, compared with the ideal direct line, there is an error of ±4.4 mm max.
