The temperature of cold junction and neu...

The temperature of cold junction and neutral temperature of a thermocouple are `15^(@)C` and `280^(@)C` respectively. The temperature of inversion is

A

`295^(@)C`

B

`265^(@)C`

C

`545^(@)C`

D

`575^(@)C`

Text Solution

Verified by Experts

`theta_(n)-theta_(c)=theta_(1)-theta_(n)`
`280-15=theta_(i)-280`
`theta_(i)=560-15`
`=545^(@)C`.
