1 NE48 spring 07 HW#3 (Total 60 points), Tuesday March 4 th Due Tuesday, March st by class time - (0points) Thermocouples measure the temperature as a result of the voltage across the two-wire contact, known as the Seebeck voltage. The relation between the voltage changes as a result of the temperature change is known as the Seebeck coefficient a -. a) If the temperature T= 600 o K, find the value of the resistor R of the OpAmp that produces the same exact output on the readout unit for each of the listed thermocouple types if =kω. TC Type Contact Materials (m/ o K) E Chromel/Constantan 60 J Iron/Constantan 5 T Copper/Constantan 40 K Chrole/Alumel 40 N Nicrosil/Nisil 38 S Platinum 0% Rhodium/Platinum B Platinum 30% Rhodium/Platinum 6% Rhodium 8 R Platinum 3% Rhodium/Platinum = = a T R output T b) If changing the feedback to a capacitor C=0μF, what is output, in m, for each thermocouple if the input is fluctuating at a frequency f=0hz Worked Solutions: oltage equation: = a T Then all voltages are obtained in m for all thermocouple types. a) To have same output for all sensors, then we can select one of the sensors as the reference. As E-type has the largest Seebeck coefficient then we can select it as the reference. We calculate the ratio between all types to that of the E-type, which yields the needed OpAmp amplification then we calculate the value of R. The other option is to
2 select a voltage value to be the standard and amplify all thermocouples voltages to the selected value. Amplification = R / R R = Amplification R R = Amplification R ( kω) ( kω) 0 TC Type Contact Materials (m/ o K) = alpha * T =c *600 (m) Setting E-type as the limit for the voltage Amplification needed R (kω) for same output E Chromel/Constantan J Iron/Constantan T Copper/Constantan K Chrole/Alumel N Nicrosil/Nisil S Platinum 0% Rhodium/Platinum B Platinum 30% Rhodium/Platinum 6% Rhodium R Platinum 3% Rhodium/Platinum Alternative solution: = a T so one3 can decide on the output voltage to be displayed as a measure of temperature, for example choosing an output voltage of 4,000μ to be the standard voltage to display then = a T = a 600 = 4000m from which it indicates α = 40 which is the K-type thermocouple. Then scale the output of each thermocouple to the same 4,000μ, which will determine the ration of amplification TC Type Contact Materials (m/ o K) = alpha * T =c *600 (m) Ratio with respect to 4000 R (kω) for same output E Chromel/Constantan J Iron/Constantan T Copper/Constantan K Chrole/Alumel N Nicrosil/Nisil S Platinum 0% Rhodium/Platinum B Platinum 30% Rhodium/Platinum 6% Rhodium R Platinum 3% Rhodium/Platinum b) Changing feedback to a capacitor will turn the OpAm to integrate the input.
