Page 15: Measurement Accuracy
MU-Thermocouple1 CAN FD – User Manual Measurement Accuracy The absolute measurement accuracy is based on the internal measurement electronics, the reference temperature sensors, and the thermocouples. Note: If an absolute temperature value and a percentage value are specified for a measurement error, the larger measurement error or the largest error deviation regarding to the measurement result applies. -
Page 16: Measurement Error Due To Thermocouples
MU-Thermocouple1 CAN FD – User Manual ±3 K at ambient temperature from -40 to 125 °C (device is specified up to 85 °C) Note: The ambient temperature should change slowly so that the contact point of the thermocouple in the socket actually corresponds to the measured reference temperature. -
Page 17: Example For Determining The Total Accuracy
MU-Thermocouple1 CAN FD – User Manual Example for Determining the Total Accuracy The following data is assumed for the example: Thermocouple type = J, class 1 Ambient temperature = 40 °C Measured temperature = 100 °C Measurement Errors due to Measurement Electronics The measurement error due to measurement electronics is 1 K or 0.2 % of the measured value. - Page 18 MU-Thermocouple1 CAN FD – User Manual The larger measurement error applies. In this case, the resulting measurement error is 1.5 K. Total Accuracy The total accuracy results from the measurement error components of the measurement electronics (1 K), reference temperature sensors (1 K), and the thermocouples (1.5 K): Total accuracy = 1 K + 1 K + 1.5 K...
