Type K Thermocouple Linearity Graph
If accuracy linearity.
Type k thermocouple linearity graph. Typical low cost type k thermocouple with standard type k connector. While the wires can survive and function at high temperatures. Application notes practical temperature measurements. Type t thermocouple and look at the voltage output.
We would like the voltmeter to read only v 1 but by. Type k thermocouple calibration equation coefficients and k type thermocouple temperature measurement using. The following graph shows residual errors after. Convert thermocouple voltage to temperature using rational polynomial functions curve fitted to nist temperature data for b type e type j type k type n type r.
Thermocouples thermocouple types type j thermocouple type k thermocouple type e thermocouple type t thermocouple. Non linearity must be corrected. Type k type j type e type t type r type s etc. Thermocouple type comparison chart.
The following curve is the standard response curve for a type k thermocouple. The deviations from perfect linearity are significant however. For example a type k thermocouple has an accuracy of 22c above 0c. Lets say the meter has an accuracy of 1c.
