• Followings are the specifications of a laser displacement sensor:
  (a) Measurement range: +10 mm
  (b) Measurement centre point: 50 mm
  (c) Resolution: 1.5 μ m
  (d) Linearity: +0.05 % FS
  (e) Response time: 60 μs
  (f) Linear output: 4-20 mA
  Answer the following questions based on Specs given above.
  (i) Draw input output graph for the sensor and properly label it.
  (ii) Evaluate the sensitivity of the sensor in mA/mm.
  (iii) An object is at a distance of 57 mm from the sensor. Determine the output of the sensor in mA?
  (iv) What is the error in the output of the sensor for the case above [part(iii)]?
