Transcribed Image Text:Q. An Oil and Gas Company has gave us a contract to design a temperature
measurement instrument
The instrument has to measure temperatures between 0 to 100C using RTD
PT100
1- The Wheatstone bridge must be leaner and proportional
2- Wheatstone bridge must start from zero volts
Design the instrument if you know the following
The resistance of the RTD PT100 is =100 Ohm's at 0°C and 139.5 Ohm's at 100°C
the input of the circuit is 5V and the output is 0.1V
Given the following table is the reading of the instrument for some temperature
values when R1=R2=R3=100 Ohm's
Temp
Vout
20
