For a certain thermocouple ,if the temperature of the cold junctions is ` 0^(@) C ` , the neutral temperature and inversion temperatures are ` 285^(@)C and 570 ^(@) C ` respectively . If the cold junction is brought to 10 ∘ C then the new neutral and inversion temperatures are respectively:

A

`285 ^(@)C and 560 ^(@) C `

B

` 285 ^(@) C and 570^(@) C `

C

` 275 ^(@) C and 560^(@)C `

D

` 275^(@) C and 570^(@) C `

Text Solution

The correct Answer is:
A
Neutral tempereature remains same. Invension temperature `, T_i= 2T_n = T_c`
`" " =2 xx 285 - 10 `
` " " = 560 ^(@) C `
