M E 345 Spring 2008 Professor John M. Cimbala Lecture 35 04/11/2008 Today, we will : Do another example problem – temperature measurement with thermistors Finish reviewing the pdf module: Temperature Measurement – Radiative temperature measuring devices Do C a n d y Q u e s t i o n s f o r C a n d y F r i d a y Start to review the pdf module: Measurement of Mechanical Quantities If time, do some example problems – displacement sensors Example Given : A thermistor has a resistance of 16330 Ω at 0.0 o C, and it drops to 6247 Ω at 20.0 o C. This thermistor is used in a simple voltage divider circuit, as sketched. V s = supply voltage = 5.00 V DC. R s = supply resistance = 10.0 k Ω . ( a ) To do : Calculate the output voltage at T = 0.0 o C. ( b ) To do : Calculate the output voltage at T = 20.0 o C. ( c ) To do : Suppose the output voltage is 2.353 V. Estimate the temperature as best as you can, given the limited amount of information provided in the problem statement.
