Thermocouple? Thermocouple type temperature sensor ?
- Two metal conductors of different nature together at two points
- the principle of resistance thermometers => change in electrical resistance of some materials with its changing temperature
- needs no power supply to indicate a temperature
- Hot and cold junction => Alumel and chromel indicating system
- contact point are maintained at equal temperature between these different metals
Thermocouple type temperature sensor :
- two dissimilar metals joined togethter at one end (called hot junction or measure junction)
The red pointer which is normally on the red line in the EGT indicators
Electrical requirements for an alumel/chromel indicating system are:
C ind Fahreneinheit?
F = C x 1.8 + 32
The main advantage of a ratiometer-type temperature indicator is that it:
A millivoltmener measuring the electromotive force between the hoz junction and the cold junction of a thermocouple can be directly graduated in temperature values provided that the temperature of the:
The measurment of the turbine tempaerature or of the EGT is carried out at the:
Iron and brass are commonly used in bimetallic therometers. because
