An RTD with a=0.003/°C and R=300 Q at 25 °C will be used to measure the temperature of hot gas flowing in a pipe. The disspation constant is 25 mW/°C, and the time constant is 5.5 s. Normal gas temperature is in the range of 100 °C to 220 °C. You are required to design a system by which the temperature variation is converted into a voltage of -2.0 to +2.0 V. Keep self-heating to 0.5 °C. Occasionally a turbulent shock wave will propagate down the pipe, causing a sudden reduction to less than 50 °C. Device a comparator alarm that will signal such an event within 3s of dropping below 100 °C. Answer the following questions: 1. The RTD resistance at 100 °C and 220 °C is: O a. 221.25 Q and 504.75 Srespectively Ob. 378.75 Q and 504.75 2 respectively O c. 378.75 Q and 95.25 Q respectively O d. 221.25 Q and 95.25 2 respectively
