A copper constantan thermocouple temperature measurement data with res

A copper constantan thermocouple temperature measurement data with respect 0oC as Temperature 30 60 70 ... 200 220 230 Voltage (mV) 0.5 0.75 0.93 ... 9.7 10.2 11.0 The copper constantan thermcouple is connected to a potentiometer whose terminals are at 30oC, the potentiometer reads 9.7 mV then the open circuit temperature of the thermocouple at 0oC is220

Answer» A copper constantan thermocouple temperature measurement data with respect

0^{o} C

Temperature	$30$	$60$	$70$	$. . .$	$200$	$220$	$230$
Voltage $(m V)$	$0.5$	$0.75$	$0.93$	$. . .$	$9.7$	$10.2$	$11.0$

The copper constantan thermcouple is connected to a potentiometer whose terminals are at

30^{o} C,

the potentiometer reads

9.7 m V

then the open circuit temperature of the thermocouple at

0^{o} C
