The following empirical data were obtained for the output from a 4 to 20 mA transmitter connected to a Type K Thermocouple:
| Current (mA) | 5.2 | 6.4 | 7.3 | 8.9 | 10.3 | 11.5 |
| Temperature (deg C) | 0 | 20 | 40 | 60 | 80 | 100 |
Plot the current versus temperature characteristic and hence calculate the sensitivity and maximum non-linearity of the device.
What is the range of this temperature measurement system?
Define the following terms as applied to instrumentation:
The transmitter contains a span and zero adjustment. Explain how you would use these to calibrate this temperature measuring system.
