1.What color is the negative lead for a Platinum 100 ice point RTD?
2.What resistance would you expect to see if you connected a Platinum 100 ice point, 0.00385 coefficients RTD to a DMM measuring ohms if the ambient temperature is 21.5°C and the RTD is immersed in a 225.0°C bath? Use both the simple linear formula and the RTD table to find this resistance value. Show your calculation. Which is the most accurate result, the table value or the formula value?
3.What is the temperature of the fluid if the ohms measured by a DMM connected to a Platinum 100 ice point, 0.00385 coefficients RTD in the fluid reads 145.6 and the room temperature is 25.0°C? Use both the simple linear formula and the RTD table to find this temperature value. Show your calculation. Which is the most accurate result, the table value or the formula value?
