You are designing a sensing circuit that uses Platinum RTD sensors (Ro = 100 N at 0°C; a = 3.92×10- 4 °C-1) to measure temperature of the engine coolant in a motor vehicle, in the range 0°C to 100°C. You are going to design a measurement system that will be interfaced to an AD converter (8-bit, 0 to +10 volts). The RTD is located in the engine cavity, and the remainder of the measurement system is remote from the engine to minimise EMI. As a voltage source for your measurement system, you use the 12 volt vehicle battery. After designing a measurement system to obtain a linear relationship between the output voltage input to the ADC and the input temperature variation. Determine the transfer function of your temperature measurement system. %3D
