Consider The Bridge Circuit And Rtd Of Example 8 1 To Select Or Design A Bridge Circuit For Measuring The Resistance Of 1 (154.52 KiB) Viewed 84 times

Consider the bridge circuit and RTD of Example 8.1. To select or design a bridge circuit for measuring the resistance of the RTD in this example, the required uncertainty in temperature would be specified. If the required uncertainty in the measured temperature is < 0.5°C, would a 1% total uncertainty in each of the resistors that make up the bridge be acceptable? Neglect the effects of lead wire resistances for this example. KNOWN A required uncertainty in temperature of +0.5°C, measured with the RTD and bridge circuit of Example 8.1. FIND The uncertainty in the measured temperature for a 1% total uncertainty in each of the resistors that make up the bridge circuit. ASSUMPTION All uncertainties are provided and evaluated at the 95% confidence level.
