A load cell is calibrated in an environment at a temperature of 21C and has the

following deflection/load characteristic:

Load (kg) 0 50 100 150 200

Deflection (mm) 0.0 1.0 2.0 3.0 4.0

When used in an environment at 35C, its characteristic changes to the following:

Load (kg) 0 50 100 150 200

Deflection (mm) 0.2 1.3 2.4 3.5 4.6

(a) Determine the sensitivity at 21C and 35C

(b) Calculate the total zero drift and sensitivity drift at 35C.

(c) Then determine the zero drift and sensitivity drift coefficients (in units of mm/C

and (mm per kg)/(C).
