A Wheatstone bridge is calibrated in an environment at a temperature of 30 C. Resistance R is replaced by an active strain gauge such that the following linear Load/resistance characteristic is recorded: a- b- d- Load (N) Resistance Change (0) e- Calculate the zero drift. Which AR is the change in resistance R2. It is then used in an environment such that the temperature is increased by 50% at which the zero drift per temperature found to be 0.3 0/C. While the sensitivity drift per temperature is found to be 0.3 (02/N)/C. It is noticed that the sensitivity became 115 % of its value at 30 C. Calculate the sensitivity drift. Determine the sensitivity at 30 C. The value of AR in Ohm. 0 Load (N) 0 Resistance Change (0) 1 0 5 Find the new Load/resistance characteristic values for the new temperature. 3 10 20 AR 7 13
