Find a linear approximation of methyl chloride pressure versus temperature from 70° to 90°C. Find the maximum error between the approximation and actual pressure in this range.
Using an RTD with
α = 0.0034 / °C and R = 100 Ω at 20 °C,
design a bridge and op amp system to provide a 0.0- to 10.0-V output for a to temperature variation. The RTD dissipation constant is 28 mW/°C. Maximum self-heating should be 0.05°C.
